Our Company
Islandaire is the fastest growing specialty air conditioning and heating
manufacturer in the country. Founded in 1992 by Robert Hansen,
it has grown into a multi-million dollar company in just a few short
years. Islandaire builds a full complement of high quality thru-the-wall
replacement air conditioners and heat pumps, water source heat pumps,
and gas units in East Setauket, New York. Each model fits perfectly into
the existing original wall sleeve assembly, thereby saving both time and
money during installations.
Our Engineering, Production, Sales and Customer Service departments
have been fully integrated to provide the maximum degree of user
satisfaction. We at Islandaire feel that this team approach to manufacturing
produces a superior overall product and assures a larger degree of
flexibility in design and production scheduling to meet tight prototyping
or construction timetables.
The Perfect Fit
Thru-wall air conditioners were developed in the late 1950's. Over the
next forty years many companies engineered, manufactured and installed
a variety of different units throughout the United States and Canada.
Today, a number of these companies are no longer in business or have
discontinued their line of thru-wall air conditioners and no longer carry
replacement parts.
Islandaire offers replacement air conditioners and heat pumps that
are interchangeable with units no longer available from the original
manufacturer. Our units are engineered to fit perfectly within the existing
wall sleeve, thereby reducing installation time and expense. They are
manufactured at our modern 75,000 square foot plant on Long Island in
New York.
Thank you for considering our products,
The Islandaire Team
2
Applications
For new construction, or as a replacement, our
packaged terminal air conditioning (PTAC) units
provide year-round comfort control for hotels, motels,
apartments, dormitories, shops, nursing homes,
assisted living centers, satellite offices, room additions
and other applications that require economical heating
and cooling.
Individually controlled PTAC units are ideal
for rooms that are not occupied during
vacancies,
holidays,
weekends
or
nights.
Individual units allow tenants to choose the
degree of comfort and operating economy.
Thermostat and fan controls are built into the digital
touch-pad, plus all units have the flexibility to convert
to a wall thermostat control, or interface into energy
management systems. Whether you are designing a
new structure or replacing PTAC units in an existing
building, Islandaire will meet your needs.
New Construction
The Islandaire EZNY Packaged Terminal Air
Conditioning (PTAC) unit is designed to meet the
needs of the architect, engineer, and contractor. For
unit installation, Islandaire’s expert support network
will assist in all applicable aspects of the construction
project, from preparing a budget to start-up.
ADVANTAGES FOR NEW CONSTRUCTION
Lower Operating Costs & Reliable Comfort for the
Occupant
Islandaire helps lower utility costs with energy
efficient units that exceed industry standards. Energy
savings are achieved in both heating and cooling
environments through efficient mechanical design
and onboard electronic logic. Separate indoor and
outdoor fans provide lower operating costs. Energy
management software is built into the unit’s standard
digital controls.
These units may also qualify for electrical power
company rebates. (Consult your local utility provider
for rebate opportunities.)
Retrofit/ Replacement
Islandaire PTAC units are engineered to fit perfectly
within most existing wall sleeves, thereby reducing
installation time and expense. There is no time wasted
on redesigning an existing wall opening or removing
an old wall sleeve. Just slide the old chassis out and
replace with a new one from Islandaire.
EZ Quick connections to the control box simplify
electrical hook-up, and our slide-out chassis eases
installation into the wall sleeve. Rapid servicing
reduces downtime: complete chassis can be replaced
in minutes without disrupting other occupants.
Design Flexibility For The Architect Engineer
• Super-quiet performance, indoors and out
• No bulky duct system
• No separate equipment room
• No water towers or additional cooling equipment
• Less sensitivity or building orientation
• Optional architectural grille to permit custom
exterior appearance

Applications (cont.)
Application
Guaranteed Quality
Considerations
Each Islandaire unit is designed to operate quietly and
efficiently and is backed by the best warranty program
available. The EZNY Unit is warranted for 12 months
parts and labor, plus an additional second through 5th
year sealed system part only warranty.
It is important for air conditioning systems to be
properly sized for each application in order to achieve
desired temperature and humidity levels. It is strongly
recommended that a professional engineer match the
PTAC units with the building structure and climate.
The following application considerations are all
important in choosing the proper PTAC system for the
building structure.
UNDERSIZING
If a PTAC unit is undersized (cooling capacity is less
than required capacity for an application), the unit
will not be able to cool the space down to the desired
temperature during very hot days.
OVERSIZING
If a PTAC unit is oversized (cooling capacity is greater
than required capacity for the specific application),
the unit will cool the space down to the desired
temperature too quickly creating a cool, yet excessively
humid, space.
Whether it is an exact replacement unit or a new
construction project, Islandaire is the smart choice for
all your air conditioning and heating needs.
Quiet Operation
The cross-flow tangential fan wheel design used in our
EZNY units provides whisper quiet operation while
delivering maximum airflow required for proper air
circulation. Separate indoor and outdoor fan motors
further reduce operating sound levels and costs.
The galvanized 18 gauge construction of the chassis and
enclosure minimizes vibration for quieter operation.
Vibration isolators on the rotary compressor keep it
running smoothly and quietly. The unit bulkhead is
fully insulated to decrease outdoor sound transmission.
The compressor is isolated to minimize vibration and
sound transmission for quiet operation.
AIR INFILTRATION
Excessive air infiltration can intensify problems
associated with undersizing or oversizing a PTAC
unit. This can be the cause of insufficient cooling,
dehumidification, or heating. Sources of air infiltration
include vents, gaps around windows and doors, and
improperly sealed floors, ceiling or wall joints.

Product Overview (EZNY)
Durable Construction
• Islandaire PTAC/PTHP units are built with durable,
quality components designed for continuous
operation in all environments.
• Our wall sleeves are constructed of thick 18-gauge
steel with a tough baked-on finish for maximum
durability.
• The outdoor fan motor is totally enclosed,
preventing damage from moisture and debris
introduced by extreme weather conditions. Both
indoor and outdoor fan motors are permanently
lubricated for extended life.
• Electrical components are located on the indoor
side of the wall protecting them from driving rain
and humidity.
All Islandaire PTAC units have special corrosion
protection that can help dramatically extend the life of
the unit. Listed below are just some of the components
that feature corrosion protections:
•Wall Sleeve – The entire wall sleeve is constructed
of 18-gauge galvanized steel. Treated inside and
outside with a baked-on based powder coat paint
to protect it from the corrosive effects of salt spray.
•Base Pan – Base pan is constructed of 18-gauge
galvanized steel and has a corrosion resistant
coating to protect it from the elements. Treated
inside and outside with a baked-on based powder
coat paint to protect it from the corrosive effects of
salt spray.
• The compressor is a reliable, high efficiency design
rotary compressor. It is hermetically sealed and
designed for continuous operation.
•Condenser Coil – Protective coating applied to
the coil to prevent corrosion and weathering. The
coils’ header plates are constructed aluminum to
prevent corrosion.
• Wall sleeves and enclosures are 18 gauge galvanized
with baked on powder coat finish. There are many
available color options.
• Condenser Fan Blade – Constructed of strong
engineering plastic that has excellent dimensional
stability over a wide range of service temperatures.
• Rugged decorator style extruded aluminum
discharge grille with matching integral control
door.
•Condenser Fan Motor – Specially coated by the
manufacturer.
All Units Have Seacoast
Construction
Application of air conditioning equipment in a
corrosive environment requires special consideration.
The corrosive nature of salt water vapor, chlorine and
acid vapor, demands a unit that can withstand these
environments. Any metal portion that is exposed to a
corrosive vapor must be specially treated.
•Compressor – Protective coating applied by the
manufacturer on the exterior to enhance equipment
life and performance.
•Outdoor Louver – Made of aluminum, etched
and anodized for maximum corrosion protection.
Available in stamped or architectural styles. Can be
painted in a wide choice of colors.

Installation Data
Installation Notes
1. Units must be installed in accordance with all
applicable codes.
2. Ensure that there is adequate clearance for
servicing and proper operation. A minimum
of 18 inches in front of the chassis is required.
Provide additional space for service technician
to work on the unit.
3. Any gaps between the air discharge outlet
and the discharge grille will cause the unit
to short cycle. This condition will shorten
compressor life. Small gaps should be sealed
with foam rubber gaskets. Larger gaps may
require a sheet metal collar (consult installing
contractor).
4. To prevent damage, this unit should NOT
be operated to provide supplementary
heating & cooling during the construction
period. The unit is designed for operation
in a normal indoor environment. Operating
this unit in unenclosed space and exposure
to construction environment may result in
permanent damage.
5. Be sure that the amperage of the dedicated
electrical service to the unit is correct.
6. After the unit is installed in the sleeve, the
shipping carton can be cut down and secured
to the unit to protect it during the construction
phase.
For Replacement Units
1. Inspect the existing wall sleeve to insure it is
not damaged and that it is securely mounted in
the wall. Use a level gauge to insure the sleeve
is pitched properly. Be sure that any gaskets
originally mounted on the wall sleeve that are
missing or worn be replaced.
2. Certain installations with extended sleeves
will require the use of baffles. These sheet
metal baffles are attached to the condenser coil
flange and have seals on their outer surface.
These seals will seat against the outdoor grill
when the unit is slid into an extended wall
sleeve. It is important that units installed
in extended wall sleeves have these baffles
installed. Without these baffles, compressor
life may be shortened.
3. Inspect the unit specification label in order
to identify the model number. At this time
voltage, capacity, and other special features
should be noted.
4. Be sure that the amperage of the dedicated
electrical service to the unit is correct. Use of
extension cord will void warranty.
Receiving Units
Do not store or transport the unit on end. For
proper storing, each carton is marked with “up”
arrows. In the event that elevator transfer makes
up-ended positioning unavoidable, absolutely
insure that the unit is in the normal upright
position for at least 24 hours before operating.
The units must be handled with care at all times.
Rough handling can damage internal electrical
and refrigeration components.

Condensate Drain Kit
Condensate Drain Kit
NOTE
An indoor/outdoor drain kit is available as an accessory
item. When a drain kit is to be installed, do so before
installing the wall sleeve in the wall.
This drain kit serves only as a link
between the unit and field-supplied
condensate drain system.
During periods of high humidity and/or during heat
pump operation condensate water will collect in the
bottom pan of the chassis. When the chassis bottom pan
is full, the water will overflow into the wall sleeve and out
the drainage holes on the back edge of the wall sleeve.
Installing the kit without connecting
it to a drainage system will result
in inadequate condensate removal,
possible leakage and corrosion.
The Condensate Drain kit contains an overflow tube to
direct excess condensate water from the bottom of the
sleeve to either an internal or external drainage path.
Because heat pumps generate condensate even during the
heating season, it is recommended to always use a drain
kit with heat pump models. Determine whether the kit
should be installed as an internal or external drain system.

ACCORDING TO TEMPLATE
The drain kit can be installed as an internal drain on the
bottom of the wall sleeve to allow condensate to drain into
an internal drain system inside of the building. Locate the
drain so that it will be on the room side of the wall when the
cabinet wall sleeve is installed.
NOTE: The drain kit must be installed prior to the installation
of the wall sleeve.
1. Locate an area on the wall sleeve that will be inside the
room when the sleeve is installed. If a subbase is installed,
locate the kit a minimum of 5 1/2” from the front flange
of the wall sleeve. This clearance will provide adequate
clearance for the subbase.
DRAIN LOCATION FROM SIDE

BUILDING DRAIN SYSTEM
DRAIN LOCATION FROM FRONT EDGE OF WALL
SLEEVE SHOULD BE A MIN. OF 5 1/2 INCHES IF
USING SUBBASE
2. Please refer to Drain Kit instructions.
3. Using figure 13 as a guide, assemble the drain gasket,
drain fitting plate, and indoor drain fitting together.
Install the assembly into the drilled holes and secure
using the two indoor mounting screws provided. The
screws must be inserted INSIDE the wall sleeve and TOP
driven down into the drain fitting plate.
Ensure drain tube is not restricted. Cover the two
screw heads with a good quality outdoor caulking (not
supplied) for additional corrosion protection.

NOTE: If the drain fitting is not connected to an indoor
drainage system immediately after the wall sleeve is
installed; plug the hole with cork (not included) to
prevent indoor water damage in case it rains.
4. Install a 1/2” ID tube or hose (not included) on the drain
fitting and interconnect it to the drain system inside of
the building. Ensure that there are no kinks or traps in
tube or hose. Kinks or traps can cause improper drainage.
5. Install the two drain blank-off plates and outdoor drain
gaskets on the outdoor portion of the wall sleeve as
shown in figure 14. These components can be installed
after the sleeve is secured in the wall opening just prior
to the installation of the condenser grille and chassis.

After the wall opening is checked for location, size,
and clearances, proceed to wall sleeve installation.
1. Install Condensate Drain Kit (if applicable).
2. Slide the wall sleeve into the wall opening. The
unit chassis must fit snugly and uniformly into
the wall sleeve without distortion.
3. Make sure that the sleeve is within the range of
minimum projections as outlined on the next
page.
4. Level wall sleeve side to side. For proper drainage,
the sleeve should be level from side to side and
one-quarter bubble in the sight glass sloping to
the outside.
5. Secure the wall sleeve by anchoring with fasteners
through the sides and top. Drill holes of proper
size and in the proper location so the screws will
engage into strong supporting members of the
wall.
DO NOT DRILL THROUGH BOTTOM
OF WALL SLEEVE. THIS CAN CAUSE
LEAKAGE OF CONDENSATE WATER
WITHIN THE WALLS.
6. Check the level of the wall sleeve and adjust if
necessary.
7. Caulk or seal around the outside of the entire
sleeve.
8. Recycle or dispose of packaging materials per
local codes.

Hydronic Coil
The Hydronic Coil is an economical way to provide
heat to a room. This coil mounts directly to the wall
sleeve, allowing the PTAC chassis to be installed
or removed independently without disturbing the
hydronic connections.
Figure 26
Hydronic Coil
The hydronic coil kit works with a heavy duty valve
motor that is electronically controlled by the PTAC
onboard controls. Also included is an aquastat that,
when installed, delays fan operation until water has
reached a minimum temperature.
The Hydronic Coil Assembly consists of the following
parts:
• Coil Protection Plate- To protect the coil surface
during shipping
• Open Cell Foam- Provides an air-tight seal
between the Room Enclosure and the hydronic
coil
• Hydronic Coil - Engineered to last
Hydronic Coil
Orientation
The Hydronic Coil can be easily re-configured
from Right to Left piping connections.
Orientation can be changed by removing the
screws from the bottom of the assembly and
re-installing the coil in the desired position.
• Coil Frame- Provides a sturdy platform for
mounting and positioning the coil.

Press the MODE button to select the desired
operation mode: Cool/Fan/Heat. Press the TEMP
+ or - buttons to set desired temperature. Press the
Fan Speed button to set the desired air flow rate
(high/med/low).
Setting the Clock
When new batteries are inserted, the default clock
setting is 00:00 A.M.. To adjust the setting to the
current time, open the back cover and push the
CLK button; the clock display will blink. Use the
HOUR and MIN buttons to set the current time.
Then press the CLK button again and close the
back cover.
Terminal connections on the main control board allow
easy conversion from an on-board control panel to a
wall mounted thermostat control (wired or wireless).
See page 40 & 41 for full details
Front Desk Control
Low voltage terminals on the main control board allow
easy connection to a front desk energy management
system. Front desk controls allow the unit to be operated
from a remote location. Front desk controls can reduce
energy consumption by allowing front desk personnel
to turn the unit off when a room is vacant.
36
System Controls and Management (cont.)
SYSTEM MANAGEMENT SOFTWARE
The Islandaire EZNY PTAC is equipped with an on-board control system that contains system management
software and sensors. Built in safety features protect the unit from the damaging effects of freezing temperatures
and power interruptions. Energy management features allow unit performance to be customized and control
power consumption. System monitoring software helps service personnel quickly correct any problems.
Listed below are some of the important control features and a brief description of their functions.
See Performance Specifications section (starting on page 44) for full details of all functions.
Fan Cycle Control
Valve Controls
The indoor fan cycle control allows the unit to operate
more efficiently. This feature conserves energy by
operating the fan only while the compressor or heater
is operating. Constant fan operation in Hi or Lo
settings is also available.
Normally open/normally closed zone valve controls
for hydronic systems.
Hydronic Heat Fan
Lockout Kit
An indoor frost sensor will disable the operation of the
compressor if freezing conditions exist. This protects
the compressor from damage due to airflow reduction
or low outdoor air temperature. When the coil
temperature rises to a safe temperature the compressor
resumes normal operation.
The control system uses an aquastat that senses the
water temperature of the hydronic system. This
aquastat prevents the indoor fan from running until
the temperature in the hydronic system has reached a
sufficient temperature to heat the room.
Room Freeze Prevention
The indoor freeze protection monitoring system
prevents unoccupied rooms from reaching freezing
levels that can damage plumbing and fixtures. This
feature is automatic and does not require any additional
settings. The freeze protection circuit operates without
regard to whether the unit is On/Off or which mode
the controls are set to.
High Temperature
Compressor Protection
The life of the compressor is extended through a built in
temperature protection circuit. The system will initiate
a compressor lockout if the compressor temperature
exceeds 154°F or if the outdoor air temperature falls
below 35°F.
Low Temperature
Compressor Protection
Custom Operation
and Continual Room
Temperature Monitoring
The system controls utilize a built-in temperature
sensor for measuring room temperature. When a predetermined (user defined) temperature set point is
reached, the on-board controls automatically adjust
unit operation to match.
See page 43 for Temperature Limiting details
Diagnostic Software
The system management software performs selfdiagnostic tests that can alert service personnel
to potential problems. Error codes are stored and
displayed on the digital display and can save service
call time during troubleshooting and maintenance.
See page 44 for a list of Error Codes
37
Control Panel
Figure 49
Control panel
Use the control panel to power on/off, select mode,
select fan speed, and adjust the set temperature.
Auto Restart Feature
To prevent multiple units from powering
up simultaneously after a power outage,
there will be a random 5 to 15 second
delay before the unit turns on after power
has been restored.
Memory Recall Feature
The control board utilizes “non-volatile”
memory; computer memory that can
retain stored information when not
powered. This allows all control settings
to be saved and recalled after a power
failure or if power is disconnected while
servicing the unit.
Power Control
The ON/OFF button turns the unit on and off.
If the electronic controls do not respond to touch
pad or remote control commands, you must unplug
the unit from the electrical outlet for five seconds
and then plug the unit back in.
Compressor Short Cycle Protection
Built-in three minute timing delay: If
cycle is interrupted, the compressor will
not restart for three minutes. On all initial
power ups there is a one time 3 minute
time delay before the unit will function.
AUTO
Display
The display shows the room temperature (return air
temperature) when the unit is in operation. When
the temperature is adjusted by pressing the “Warm”
or “Cool” buttons the display briefly shows the set
temperature, for three seconds and then defaults
back to room temperature.
Mode Control - Cool, Fan,
and Heat
A light will indicate which mode is currently being
utilized.
Cool Mode: The unit will circulate and cool the air.
Fan Mode: The unit will only circulate the air.
Heat Mode: The unit will circulate and heat the air.
Heater Safety Feature
When heater is powered off, fan will
automatically stay on and run for 60 seconds
to ensure the removal of residual heat.
38
Control Panel (cont.)
Fan Speed Control Low, High, and Auto
Freeze Protection Feature
If the temperature in a vacant room falls
below 50°F (4.4°C) the freeze prevention
thermostat automatically starts the heating
cycle to prevent freezing conditions. All
other operations will be disabled until the
temperature rises above 58°F.
The fan speed settings are adjusted with the Fan
button. Each time the button is depressed it changes
the setting between Low, High and Auto. A light will
indicate which setting is currently being used.
Figure 50
Fan Controls - Digital Control Panel
When the temperature of the freeze
prevention thermostat rises above 58°F the
system will resume normal operations.
AUTO
OPERATIONAL PRACTICES
If either the Low or High fan settings are selected
the fan will continuously operate in the selected
Low or High speed even if the set temperature has
been reached.
When the Auto feature is selected, while the air
conditioner is in the COOL or HEAT mode, the
fan speeds will change between low and high
automatically as the temperature in the room
changes and the fan will cycle off when the set
temperature is reached.
Temperature Controls
The Warm and Cool buttons are used to raise or
lower the set temperature. By depressing both
buttons at once, the display will toggle between
Celsius and Fahrenheit.
Figure 51
Temp Controls - Digital Control Panel
• Do not block airflow. Efficient operation of the
unit depends on free circulation of air over the
coils.
Paper, leaves, and other debris can reduce
efficiency and cause serious damage to the
compressor.
• Ensure that objects such as drapes, furniture,
or plants are not blocking supply and return
airflow.
• Do NOT operate unit with front panel removed
or without filter, as this will void any warranties.
• Keep doors and windows closed. Leaving them
open will increase the workload on the unit and
will result in higher operating cost and excessive
condensate.
• Do NOT operate unit during construction. Construction dust can clog filter and cause
permanent damage to other components.

Remote Thermostats
Remote Wall Mounted Thermostats
Remote Thermostat
Control
The EZNY can be controlled by any remote electronic
thermostat that can interface with RCBWYG terminals.
A Wiring harness is provided with conductors for
all applications (Heat Cool, Heat Pump, Multispeed
Fan, etc.) see page 41. The Control Selection jumper
must be in T’STAT position. During a call, the remote
thermostat will pass R back to the controller on a
respective terminal. The push buttons on the touchpad
become inactive in the remote thermostat mode.
Note: In terms of outputs, there are two types of
thermostats: Relay Contacts and Solid State.
Manufacturers of solid state output thermostats
include loading resistors in their installation kits. These
(560 Ohm 3W) resistors are meant to load thermostat
solid state outputs in order for the output voltage to
be either 0 or 24VAC, i.e. no floating voltage. These
resistors are connected from W, Y, G to common (C),
respectively
You can wire any type of 24Vac thermostat straight
into the Remote Thermostat Interface on the PTAC
control board (see page 41).
Wireless Wall Thermostat
Wireless wall thermostats are designed to provide
precise temperature control without the installation
labor and expense of wiring.
• Powered by AA batteries
Remote Control Node
Used with a wireless wall thermostat, the RCN
communicates with the thermostat using unlicensed
900 MHz, radio frequency energy.
Energy Saving Options
Automatic
Change-Over
Remote
Mounted
Thermostats can be obtained to switch from heating
to cooling and from cooling to heating automatically.
With automatic change over, the operation of the
heating cycle or the cooling cycle is determined by the
temperature requirement of the space.
Most thermostats with this feature are set to change
over when the room temperature varies 3-1/2°F from
the set-point. The unit is placed in the cooling mode
when the set-point is over 3-1/2°F; 3-1/2°F under the
set point places the unit in the heating mode. This
3-1/2°F variation is usually adjustable from a 1/2°F
dead band to a 5°F dead band. Each cycle is run until
the set point temperature is reached, then that cycle
is de-energized. On some thermostats, the automatic
change over function can be overridden manually by
moving the thermostat selector switch to “heat” or to
“cool.”
The fan operation, with an automatic change over
thermostat, is controlled by the fan selector switch.
When placed in the “fan” mode, the fan runs
continuously. When placed in the “auto” mode, the
fan will only energize when the thermostat calls for
heating or cooling.
• Mounts in any suitable location that will provide an
accurate room temperature reading.
• Large LCD display provides the user with current
room temperature, set point temperature, time,
program interval, and other system status
information.

be ETL listed for safety and tested to ARI 380-82 for
performance. Units should be Islandaire EZNY or
equal.
Overall dimensions for the room enclosure shall
not exceed 52" wide, 22-1/2" high, and 17-3/4" deep.
Overall dimensions of the wall sleeve shall be 16" high,
42" wide and (13-3/4"/24”) deep. All units shall operate
on 115, 208 or 230 volts, 60 Hz, 1 phase power.
The minimum energy efficiency ratio (EER) in BTU
per hour per watt for each PTAC unit must be in
compliance with ASHRAE 90.1 new construction
criteria, for all sizes using R-410A Refrigerant.
Heating/Cooling Chassis –
Chassis shall be slide-in, plug-in type with a selfcontained, hermetically sealed refrigerant circuit. All
chassis sheet metal parts shall be constructed of either
powder-coated G-60 galvanized steel for maximum
corrosion resistance. The chassis shall consist of the
following components:
Vibration isolated compressor; rifled copper tubed
evaporator and condenser coils with high efficiency
raised lance aluminum plate fins mechanically
expanded to the tubes for maximum heat transfer;
and a capillary restrictor type refrigerant metering
device. Coils shall be factory tested at 600 psig. A
positive closing fresh air damper (72 CFM) may be
located within the chassis to provide fresh air during
fan operation.
The evaporator fan motor shall be a two-speed, totally
enclosed and permanently lubricated fan motor. It
must be positioned on the indoor side of the bulkhead.
The indoor blower fan shall be a forward-curved
tangential design to provide even airflow across the
evaporator coil.
During the cooling cycle:
The compressor, the outdoor fan motor and the
indoor fan motor shall be energized. Condensation
accumulated on the evaporator coil shall be drained
into the outdoor section where it is to be picked up by
the condenser fan/slinger ring and evaporated against
the outdoor coil. In the cool mode, the compressor will
cut in if the space temperature is at least 1°F above the
thermostat set point and will cut out when the space
temperature is approximately 2°F below set point,
subject to timing protections.
During the heating cycle:
Hydronic Heat – Control will call for heat when the
space temperature is 1°F lower that the set point. The
control will cease its call when the space temperature
is 3°F or higher than set point.
Only the indoor fan motor is energized. The outdoor
condenser fan motor and compressor shall not be
energized.
Continuous or Fan Cycle setting:
Continuous Fan - Fan runs continuously at pre-selected
Hi or Lo Speed.

Performance Specifications (cont.)
Optional Back Up Electric Heat
Control module –
Heater shall be open wire type with quick response
and high limit cutout. Heaters shall be sized to meet
heating requirements as shown on the schedule.
Electric resistance heaters must be placed behind
the indoor evaporator coil and must not be visible
through the indoor discharge grille. When the heater
cuts out the indoor fan continues to run for 15 seconds
at the set speed, regardless of On or Off mode. After
15 seconds the fan will stop running if unit is in Off
mode, else the fan operation will depend on Fan.
The PTAC Control module is used to control a PTAC
unit that includes both an integral air conditioner
and a source of heat. The Digital Control is operated
with a Touchpad, IR Remote or 24 volt, Wall Mounted
Thermostat.
Hydronic Heat –
When the control is in heat mode and calling for heat,
the indoor fan shall not turn on until the Aquastat
sensor closes. If at any time while the unit is in heat
mode the Aquastat sensor opens, the indoor fan shall
turn off immediately. Control will check if the Aquastat
sensor is closed for 2 seconds before resuming indoor
fan operation.
Hydronic with Back Up Electric heat – Upon the
call for heating and thereafter the Aquastat sensor
temperature will be monitored. A trend in Aquastat
sensor Temperature shall determine which form
of heat is to be used. If during the 90 seconds that
Hydronic is the heat source and the Aquastat sensor is
above 90°F then Hydronic is the heat source. If during
this 90 seconds, the temperature of the Aquastat
sensor is below 90°F then Electric is the heat source.
The hydronic valve is opened for 90 seconds. After 90
seconds whether Hydronic or Electric provides the
heating is determined by the following:
If Aquastat sensor temperature is less that 90°F,
Electric provides the heat.
If Aquastat sensor temperature is greater than 90°F,
Hydronic provides the heat.
Room freeze protection:
When the unit senses temperatures of 50°F or lower in
an unoccupied room, the heat mode is automatically
initiated to prevent freezing. The outdoor fan and
compressor are stopped to help prevent coil freeze.
Compressor protection:
The life of the compressor is extended through built in
protection logic such as:
• High temperature protection if the compressor
temperature exceeds 154°F
• Minimum run time
• Minimum off time
• Random restart after a power outage
• Low ambient lockout when the outdoor air
temperature falls below 35°F
Digital Control:
Shall have solid state digital control operated via a unit
mounted touchpad, handheld infra-red or remote wall
mounted thermostat. Shall include space temperature
control and unit ON or OFF, and the following:
Cooling – Compressor and Outdoor fan, Indoor fan –
HI, LOW, CONSTANT or FAN CYCLE.
