SIMPLISSIMO SETTINGS
System programming will performed using the Intelli-Hood 2 Simplissimo.
Exhaust Temp Span (01) - This sets up the temperature span for mapping exhaust temperature to the VFD speed reference
signal. The low end of the span relates to 0% VFD speed. It will be set through the Simplissimo in parameter -15, but
will default to 75F (with the exception of settings 9 and 10, which will change the low end to 70F). The high end of
the span relates to max VFD speed. This will be set in the Simplissimo in parameter -01 and have a default of 90F and
maximum of 150F. VFD speed will vary proportionally to the temperature between the min and max. The speed
reference signal will be sent to the VFDs via RS-485 serial communication.
Min Fan Speed (02) - This sets up the minimum speed that the VFD will run. Min speed must be less than maximum speed.
If the operator tries to set up a minimum speed greater than or equal to maximum speed, the error beep will sound. If
Auto is chosen, the minimum speed will start at 20% and automatically adjust up to 50% speed, based on the
monitoring of temperature rise.
Max Fan Speed (03) - This sets up the maximum speed that the VFD will run. Max speed must be greater than minimum
speed. If the operator tries to set up a maximum speed less than or equal to minimum speed, the error beep will sound.
Exhaust Temp Alarm Set Point (04) - This sets up the temperature set point for the exhaust alarm output. When the
temperature alarm set point is reached on a particular hood, the speed reference bars will flash while the hood’s speed
is displayed. If a temperature alarm is selected for either the hood or system 24VAC output, when the set point is
reached 24VAC will be sent to the I/O board terminals specified. If item 6-10 is selected, then when the hood's speed
is being displayed on the bar graph and the exhaust temperature exceeds the temperature set point, the keypad's beeper
will sound. The keypad will go through 12 iterations of beeping the beeper for the alarm. If the fans are turned off
and the high temperature alarm set point is reached, the exhaust fans will automatically turn on.
Hood 24VAC Output (05) - This sets up the function of the auxiliary 24VAC output accessible from the hood menu. For
example, Hood 1 will control Output #1, Hood 2 will control Output #2, etc.
No - The 24 VAC is not used and disabled.
Exhaust Temp - The output is used for the exhaust temp alarm set point and operates according to the setting in
Exhaust Temp Alarm Set Point Menu.
Smoke - The output is used as a smoke alarm. 24VAC will be sent to the I/O board terminals whenever the optic
sensors detect smoke.
Fan On – 24 VAC will be sent to the I/O board terminals when the hood is turned on and operating normally. If a
fault is detected or the hood is not running, the 24VAC will turn off.
MUA Damper - The output is used to control a damper. When the fans are turned on, 24 VAC is sent to the I/O board
terminals. When the fans are turned off, the 24VAC is turned off as well.
MUA Heat - The output is used to control make-up air heat. At default settings, when the kitchen temperature is < 68
F, the output energizes to send a signal to heat. If the supply air is less than 50F, a signal to heat will be given
regardless of the space temperature. The minimum speed shall also change to 50% unless otherwise specified in the
Remote Input Menu, item Thermostat & x%. When the kitchen temperature is > 70 F and the supply temperature is >
50 F, the heat is off and the minimum speed in Min Fan Speed Menu is used. The MUA heat set points may be
changed in parameters 9-29 and 9-30.
MUA Cool - The output is used to call for cooling if the kitchen temperature rises above the setting in 9-31. When the
set point is reached, 24VAC will be sent to the I/O board terminals.
Page 10
Mom Relay - The output is used to control a momentary relay. When the fans are turned off, 24 VAC is sent for 3
seconds and then turned off.
Fault – When the keypad is displaying a fault, then 24 VAC is sent until the fault is cleared.
24/7 –24 VAC will be sent to the terminals constantly, as long as the processor has power.
Number Sensors (06) - This sets up the number of 100 Ohm RTDs in series and/or optics for the given hood. If 10, then there
are no sensors for the hood. The hood can have from 1 to 4 temperature sensors and 1 optics sensor; or it can have
from 1 to 4 temperature sensors only; or it can have just 1 optic sensor. Temperature sensors are always connected via
the hood channel. Optic Channel 1 is the default for Hood 1, Optic Channel 2 is the default for Hood 2, etc; however
optics may be shared between hoods programming the desired optic channel in parameter 13.
Auto Fan On/Off (07) – These settings allow for each hood to be automatically turned on and off. When setting 2 through 6
are used, the fans will turn on when the first temperature is reached in hood parameter 16, and will run at the night
setback (NSB) speed after the temperature has dropped to the second set point in parameter 16 for at least 15 minutes.
While in NSB, the hood will not be displayed on the keypad.
Heat x%: In these settings, the fan(s) will turn on when the temperature reaches 90 F (or the temperature programmed
in parameter 16). The fans will modulate based on the temperature span until the temperature drops to 75 F or less for
at least 15 minutes, after which the hood will not be displayed on the keypad and the fans will either shut off (0%) or
run at the speed programmed for night setback (5-20%).
VFD Address (08) - This sets up the address for which VFD is connected for this hood. If No is selected, then there is no VFD
for the hood and that channel will not display on the keypad during normal operation. Primary VFD addresses are 1-8.
Additional addresses may be set up on the hood as slave drives in parameter 09.
Add. VFD Address (09) – These settings allow for programming of ‘slave’ drives. By utilizing this parameter, up to three
VFDs may be controlled by each channel.
Short Cycle Hood Ratio (10) - This sets up the short cycle hood ratio of supply air to exhaust air. To prevent the outdoor
supply air temperature from influencing the exhaust temperature sensor, a cooking temperature is calculated. Use the
following equation to determine the calculated temperature used to proportionally vary VFD speed:
Tc = [Te - (x)Ts] / [1-x]
Te = actual exhaust air temperature
Ts = actual outdoor supply air temperature
x = short cycle hood ratio
x = Cs / Ce
Cs = supply airflow in cfm
Ce = exhaust airflow in cfm
Tc = calculated cooking temperature
Hood # Relay Input (11) - This sets up how the hood will respond to a dry contact closure across the remote input terminals.
Hood 1 corresponds to Remote Input #1, Hood 2 corresponds to Remote Input #2, etc.
Remote ON/OFF - The remote input terminals are used for remotely turning the fans on and off, just as if the keypad
FAN switch were pressed. A contact closure equals FAN ON. This functionality may be overridden by the keypad.
Remote Enable - The remote input terminals are used for remotely enabling or disabling the ability of the fans to run.
If this parameter is programmed, then a remote input will be required in order for the fans to run (i.e. keypad will not
override). A contact closure equals FAN ENABLE. A high temperature alarm will override this function.
Page 11
100% on Closure - When a closure is made on the remote input terminals the associated fan(s) will run at 100%
speed. Fan speed will return to modulation when the closure is removed.
T-stat & x% - A contact closure at the remote input terminals will change the minimum speed to x% instead of the
minimum speed called out in Min Fan Speed Menu. Also, any output terminals programmed for MUA heat will be
activated if programmed in either hood parameter 05 or system parameter 09. This signal is indicated on the keypad
by a green LED in the fault display. When the contact opens, then the minimum speed in Min Fan Speed Menu is
used, the output terminals will be deactivated, and the green LED in the fault display is turned off.
Relay Inputs to Utilize (12) - This determines which of the remote inputs the hood will recognize (and follow). In the event
that the hood and system inputs are programmed identically, an input on either will affect the hood (given that the
input in question is on the utilize list).
Hood Only – Only the remote input corresponding to the hood number will be recognized
Hood & System 1, 2 – The corresponding hood number input will be recognized along with system inputs 1 and 2.
System 1 – Only the corresponding system input 1 will be recognized
System 2 – Only the corresponding system input 2 will be recognized
Hood & System 1 - The hood input as well as the system input 1 will be recognized.
Hood & System 2 - The hood input as well as the system input 2 will be recognized.
None - None of the remote inputs will have any effect on this hood
Optic Sensor Address (13) – This determines which optic channel the hood will be affected by. This would be used for
occasions where the exhaust fan may be modulated independently on temperature, but multiple channels share an optic
sensor. The default is for the corresponding hood number.
Scheduling (14) – This determines during which schedules that the hood will follow. The schedule times and parameters are
programmed in the system menu (9-12 through 9-21).
Temp Span Min (15) – This parameter may be used to adjust the low end of the temperature span. Unless either 9 or 10 are
selected in parameter 01, then the default is 75F.
Auto On/Off Temp (16) – This parameter may be used to adjust the temperatures at which the fan automatically turns on and
off when auto on/off is programmed in parameter 07.
CFM Ratio for MUA/AUX Output (17) – This setting allows the various hoods to be weighted when the ‘average’ VFD
speed is being calculated. The system will add the numbers input from all active hoods, and use this sum to determine
a ratio of how the exhaust air is distributed. e.g. if hood 1 is weighted at 2 and hood 2 at a 1, then hood 1 will account
for 67% of the MUA in the ‘average’ mode while hood 2 will account for 33%. If the setting is programmed to
“None”, then the hood will be discounted in the auxiliary average.
Cable Length (18) – This setting allows for long runs of cable to be accounted for. The additional cable length will add a
known resistance to the RTD reading when dealing with temperature probes, and will thus be accounted for by setting
this parameter. When programming this setting the actual cable length between the I/O Processor and the farthest
temperature probe on that channel must be entered. The cable length is selectable in five foot increments.
VFD Software (19) – This parameter provides for adjusting the communication protocol used for the VFDs being controlled by
the programmed hood signal.

temperature setting must be lower than the space temperature setting. If an attempt is made to program a setting equal
to or greater than the space setting, an error beep will sound. If the Tk>Ts setting is chosen, comfort mode will
activate whenever supply temperature is less than the space temperature and space temperature is greater than the
space set point.
MUA Heat if Kitchen < (9-28) – This parameter allows the set point for energizing the heating circuit (hood parameter 05 and
system parameter 09) based on space temperature to be adjusted when the MUA Heat option is selected in one of the
24VAC outputs or the system relay.
MUA Heat if Supply < (9-29) – This parameter allows the set point for energizing the heating circuit (hood parameter 05 and
system parameter 09) based on supply air temperature to be adjusted when the MUA Heat option is selected in one of
the 24VAC outputs or the system relay.
MUA Cool if Kitchen > (9-30) – This parameter allows the set point for energizing the cooling circuit based on space
temperature to be adjusted when the MUA Cool option is selected in one of the 24VAC outputs or the system relay.
Add. MUA Address (9-31) – This parameter provides for addressing additional VFDs to be driven by the AUX signal.
Additional addresses are 31 through 33.
Page 17
MUA VFD Software (9-32) – This parameter provides for adjusting the communication protocol used for the VFDs being
controlled by the AUX signal.
Gain for AUX Input (9-33) – This parameter functions the same as the AUX Weighting in the hood menu, only it refers to the
external input from the I/O board. This function has no effect unless parameter 9-01 is set for average.
Modem Options (9-34) – This adds capability to set communication options. It enables and disables the auto dial-out
capability and also specifies if an analog, wireless dial-up, or wireless IP modem is installed. For analog modems, an
option is also selectable to first dial a ‘9’ to retrieve an outside line.
Data Log Sample Rate (9-35) – This parameter sets the sample rate at which the system stores data. Parameters for data
logging are as follows:
•
System will automatically log the operation of the active hoods connected to the processor.
•
When the memory is full, the earliest fan speed data will be over-written. This will create a ‘moving log’ of
system operation.
US/SI Units Selection (9-36) – This parameter allows for the adjustment of the temperature to be in either Fahrenheit or
Celsius and for the time display to be either 12-hour or 24-hour. When the clock is set for 24-hour mode, A or P will
not be displayed with the day of the week.
Day On/Day Off Monitoring (9-37) – This parameter forces the system to alternate between running at variable speeds and
running at 100% speed. This may be used to provide real-comparison data when energy monitors are being used to
verify energy savings.
Smoke Density (9-38) – This parameter sets the optics to act proportionally (Proportional) or at a fixed level of sensitivity that
will send the fans to 100% speed once the programmed level is exceeded.
Fire Safety (9-39) – This parameter sets which hood(s) will be affected in a temperature alarm condition. When set for Alarm
Hood Only, only the fan associated with the alarming hood will turn on and operate at 100% speed. When set for All
Hoods, the system will turn on all of the fans whenever a temperature alarm condition is met at any one of the hoods.
Full Speed @ Start (9-40) – This determines the length of time that the fan will run at 100% at startup. If No is selected
(default), then the fan will immediately modulate based on temperature.

else go to step 4.
2. Remove hood cable from processor.
3. Remove temperature cable from first header board and place in processor. – If symptom remains
temperature cable or probe is bad, else hood cable is bad.
4. Place optic cable in first header board. – If symptom repeats optic cable is bad, else continue.
5. Place APU to APU cable in first header board, and remove optic cable from the second header
board. - If symptom repeats APU to APU cable is bad, else continue.
6. Place optic cable in second header board. - If symptom repeats optic cable is bad.
Symptom:
Keypad display is jumbled.
Problem:
Open or short in keypad cable.
Solution:
Replace keypad cable.
Symptom:
VFD fault or odd VFD behavior.
Problem:
Open or short in a VFD cable.
Solution:
1. Disconnect all VFDs that are not directly connected to the IOP, cycle the fan button.
2. Connect the second VFD to the first and cycle the fan button.
3. Continue to add VFDs to the chain until the symptom repeats itself, at which point the last cable
connected is defective and should be replaced.

Output Wire Lengths
Due to possibility for interference, the distance between the drive output and the motor being
controlled must be less than a specified distance. If the distances specified below must be
exceeded, an output filter must be installed on the application. When installing output filters, the
filters should be as close to the drive as possible and must be installed no farther than 15 feet
(4.5 m) from the drive in order to be effective. Installing the filters farther away than 15 feet will
cause the filters to absorb the harmonics and voltage spikes, causing them to fail prematurely.

TEMPERATURE SENSORS
FUNCTIONAL
DESCRIPTION
A Temperature Sensor is mounted in the exhaust duct of each hood to monitor the
exhaust air temperature. A serial RS-485 signal is sent from the Input/Output Processor
to the respective Variable Frequency Drive(s) to automatically adjust fan speed for each
hood based on the actual heat load.
(The temperature span is factory set at 75F-90F which means the fans run at minimum
speed at 75F and increase proportionately to 100% speed at 90F. Both the temperature
span and minimum speed can be set at the Keypad).
*** For applications involving short-cycle hoods, a second Temperature Sensor is also
mounted in one of the supply ducts. The purpose is to prevent the exhaust air readings from
being
influenced by the short-cycle supply air.
GENERAL SPECIFICATIONS
- Stainless steel housing (304L) for durable construction and smooth finish
- Stainless steel temperature probe: 1/4”OD with 0.20” wall thickness
- Temperature rating: 1000F

OPTIC SENSORS
The Optic Sensors consist of an Emitter and a Receiver which get mounted on opposite
ends of the kitchen hood. An infrared beam spans the length of the hood to detect any
smoke/vapors generated by the cooking appliances. Upon detection, a signal is sent to
the Input/Output Processor which automatically ramps the fan(s) up to 100% speed.
- Stainless steel housing (304 L) for durable construction and smooth finish
- Spring push buttons on housing for easy removal and cleaning
- Stainless steel air purge pipe (304 L)

AIR PURGE UNIT
The Air Purge Unit Enclosure consists of a miniature blower mounted on each end of the
hood, over the Optic Sensors inside a steel box. The purpose of the blower is to
pressurize the Emitter and Receiver housing with clean air to prevent grease vapors
from “fouling” the optic lenses, while the box also houses a distribution board to route the
control cables to the sensors on the hood.
- Compact & rugged blower construction for easy installation and maximum life
- Permanently lubricated ball bearings to eliminate maintenance
- 25 CFM at free air
- 14ga Galvanized Steel

VARIABLE FREQUENCY DRIVE (VFD)
The electronic motor starter is a variable frequency drive (VFD) which is used to control
the exhaust and supply fan motors. The VFD modulates the speed of the fan motors by
varying the output voltage and frequency based on a serial RS-485 signal received from
the Input/Output Processor. The VFD also sends a feedback signal to the Input/Output
Processor in order for the keypad to display the actual speed of the motor.
- NEMA 1 Enclosure (NEMA 4 Available).
- Soft-start capability.
- Digital keypad displays output frequency, current, voltage, and allows programming for
field modifications.
- Protective Functions: motor overload, overheating, overcurrent,
overvoltage, output shorts, etc.
- High and low frequency limiters.
- Adjustable torque boost.

the entire temperature span
and optimize energy savings.
If programmed, fans will activate in
case of a temperature alarm to possibly
avert a fire condition.
Temperature span is manually set
through the programmable menu.
Future Options
Space and supply air sensors can
determine if free cooling may be
utilized and will override the
temperature span to increase fan
speed and act as an economizer.
Optic Sensors
IAQ Sensors
under development.
Appliance Input
Utilizing the optic sensors allows the
system to operate more efficiently by
watching for any traces of effluent.
HVAC Input
Hood 24VAC Output
BAS Input
System 24VAC Output
24VAC programmable output for each
hood. Can be used for alarm output,
fan/equipment interlock, etc.
Future Options
Remote inputs from humidity,
CO, CO2 sensors or BAS system
that may adjust fan speed.
System Relay
24VAC programmable output based in
system menu. Can be used for alarm
output, fan/equipment interlock, etc.
Shunt-Trip Shutdown
under development.
Arrange for automatic fan speed adjustment
based on state of cooking equipment.
Programmable Form-C relay with
capacity of 15A @ 230VAC
Integral Datalogger
Ability to ramp EFs to full speed and
shut down supply fans with simple
jumper setting during startup.
