E-Series packaged rooftop unit product line was created to save energy with intelligence by offering some
of the highest energy efficiency ratings available with a powerful, easy to use unit controller. This makes
E-Series rooftop units perfect for business owners looking for an HVAC product with the lowest total cost of
ownership. E-Series rooftop units feature:
•
Hinged Access Panels - Provide quick access to components and protect panels and roof from damage
during servicing.
• Isolated Compressor Compartment - Allows performance check during normal compressor operation
without disrupting airflow.
• Corrosion-Resistant Removable Drain Pan - Provides improved serviceability.
• Thermostatic Expansion Valves - Provide peak cooling performance across the entire application range.
• Scroll Compressors - Standard on all units for reliable, long-term operation.
• Eco-last™ Coil System - Smaller, lighter condenser coil.
• Constant Air Volume (CAV) or Variable Air Volume (VAV) Blower Option - Allows constant or variable
air delivery.
• Auto-Tensioner for Blower Belt - Factory option ensures blower is delivering the proper airflow for comfort, while maximizing efficiency and belt life.
• MERV 13 Filters - Available as factory or field option, provide an enhanced level of indoor air quality, and
can help the building qualify for additional LEED credits.
• Foil-Faced Insulation - Insulation on all internal surfaces that have contact with airflow helps minimize
airborne fibers and improve IAQ.
Intelli-guide™ Control System
Standard on every E-Series rooftop unit, the new Intelli-guide™ unit controller is
the heart of the Allied controls offering. The intuitive user interface makes setup,
troubleshooting and service easier than ever. Each unit tracks the runtime of every
major component and records the date and time when service or maintenance is
performed.
WireRight™ System
The WireRight system simplifies field sensor or thermostat installation through advanced connectors that are
keyed and color-coded to help prevent miswiring. Not only is the wire coloring scheme standardized across all
models, each connection is intuitively labeled to make troubleshooting and servicing quick and easy.

N ECONOMIZER/EXHAUST
OPTIONS
Economizer - Downflow or
Horizontal With Air Hood
Parallel gear-driven action return
air and outdoor air dampers,
plug-in connections to unit, nylon
bearings, neoprene seals, 24volt, fully-modulating, spring
return motor, adjustable minimum
damper position. Outdoor air hoods
for economizer and downflow
barometric relief dampers furnished.
Choice of economizer control
options:
1. Differential Sensible Control
Factory setting. Uses outdoor
air and return air sensors that
are furnished with the unit. The
compares outdoor air and
return air and using setpoints,
enables the economizer when
the outdoor air temperature is
below the configured setpoint
and cooler than return air.
NOTE - Differential Sensible
Control can be configured in the
field to provide Offset Differential
Sensible Control or Single
Sensible Control.
In Offset Differential Sensible
Control mode, the economizer
is enabled if the temperature
differential (offset) between
outdoor air and return air reaches
the configured setpoint.
In Single Sensible Control mode,
the economizer is enabled when
outdoor air temperature falls below
the configured setpoint.
2. Global Control
The unit controller
communicates with a DDC
system with one global sensor
(enthalpy or sensible) to
determine whether outside air
is suitable for free cooling on all
units connected to the control
system. Sensor must be field
provided.
3. Single Enthalpy Control
Outdoor air enthalpy sensor
enables economizer if the
outdoor enthalpy is less than the
setpoint of the board.
4. Differential Enthalpy Control
Two solid-state enthalpy sensors
allow the economizer control to
select between outdoor air or
return air, whichever has lower
enthalpy.
Outdoor Air CFM Control
Maintains constant outdoor air
CFM levels for VAV units with
variable frequency drives on
the supply fan and varying unit
airflows. Using information from a
velocity sensor located in the units’
outdoor air section, the Intelliguide™ Unit Controller changes
the economizer position to help
minimize the effect of supply fan
speed changes on outdoor air
CFM levels. Setpoint for outdoor
air CFM is established by field
testing.
NOTE - Not available with Demand
Control Ventilation (CO2 Sensor).
Downflow Barometric Relief
Dampers
O Allow relief of excess air, aluminum
blade dampers prevent blow back
and outdoor air infiltration during
off cycle, bird screen furnished.

variable frequency drive) have
100% capacity and can be ordered
with an optional VFD bypass. Fans
feature solid-state analog pressure
transducer control which senses
differential pressure between
conditioned space and outdoor
air to regulate fan speed. See
High Static Power Exhaust Blower
Tables.
NOTE - High Static Power Exhaust
is field installed but must be
ordered at the same time as the
rooftop unit so the unit can be
factory configured for this option.

NOTE - Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable
output of motors furnished are shown. In Canada, nominal motor output is also maximum usable motor output. If motors of comparable output are used, be sure to keep
within the service factor limitations outlined on the motor nameplate.
