Supply Air Temperature (Universal Input 1) 

The supply air temperature sensor ships with the unit. 

The sensor wire is factory-provided and is preterminated 

in the unit. The sensor ships loose (in the 

control panel) and must be field installed downstream 

of the unit, with the probe in the supply duct. The 

supply air sensor is a 10kΩ thermistor (at 77°F), type 

III thermistor curve. 

Cooling Coil Leaving Air Temperature (Universal Input 2) 

The coil leaving air temperature sensor is factory 

wired and installed in the coil section of the unit 

between the evaporator and reheat coils, closest to the 

evaporator coil. The coil leaving air sensor is a 10kΩ 

thermistor (at 77°F), type III thermistor curve. 

Outside Air Temperature (Universal Input 3) 

The outside air temperature sensor is factory wired 

and installed on the outside of the unit under the 

outside air damper hood. The sensor is a combination 

sensor (temperature and relative humidity). The 

outside air temperature sensor is a 10kΩ thermistor 

(at 77°F), type III thermistor curve. 

Space Temperature (Universal Input 4) 

The space temperature sensor must be field wired and 

installed. Refer to wiring instructions in this manual. 

The space temperature sensor is a 10kΩ thermistor 

(at 77°F), type III thermistor curve. 

Outside Air Relative Humidity (Universal Input 5) 

The outside air relative sensor is factory wired and 

installed on the outside of the unit under the outside 

air damper hood. The sensor is a combination sensor 

(temperature and relative humidity). The outside air 

relative humidity sensor is a DC voltage device (0-10 

VDC, 0-100% RH). 

Space Relative Humidity (Universal Input 6) 

The space temperature sensor must be field wired and 

installed. Refer to wiring instructions in this manual. 

The space relative humidity sensor is a DC voltage 

device (0-10 VDC, 0-100% RH). 

Damper End Switch (Universal Input 7) 

Units may be equipped with only the outside air 

damper (100% outside air only) or outside and return 

dampers (100% outside air with recirculation). In all 

cases, the damper actuator is controlled with a 0-10 

VDC signal from the controller to the actuator. When 

actuators are included for outside and return dampers, 

both dampers are concurrently controlled with one 0- 

10 VDC signal (opposing direction handled 

physically with the actuators). For applications with 

one damper actuator, the damper end contact closure 

is wired to the controller to indicate when the damper 

is open sufficiently for air flow. For applications with 

both outside and return dampers, the end switches are 

wired in parallel. In those applications, at least one 

end switch must close to indicate the damper is open 

sufficiently for air flow. 

Supply Fan Status (Universal Input 8) 

The supply fan status of the unit is determined with a 

differential pressure switch. The switch is mounted in 

the control panel with tubing running to the high and 

low pressure sides of the fan. When the fan speed 

increases enough to create the pressure differential, 

the contacts internal to the switch close, confirming 

fan operation. 

High / Low Pressure Cutout, Circuit A (Universal Input 9) 

Each refrigeration circuit (one or two compressors 

per circuit, depending on the unit) includes both high 

and low pressure switches. When the refrigerant 

pressure of the circuit exceeds the switch limit, the 

cutout device contacts open, causing a shutdown 

alarm. When the high pressure condition is 

addressed, the high pressure cutout device must be 

manually reset by pressing the red button on the 

device. When the refrigerant pressure of the circuit 

falls below the switch limit, the cutout device 

contacts open, causing a shutdown alarm. The low 

pressure cutout device automatically resets when the 

fault condition is addressed. 

High / Low Pressure Cutout, Circuit B (Universal Input 10) 

Each refrigeration circuit (one or two compressors 

per circuit, depending on the unit) includes both high 

and low pressure switches. When the refrigerant 

pressure of the circuit exceeds the switch limit, the 

cutout device contacts open, causing a shutdown 

alarm. When the high pressure condition is 

addressed, the high pressure cutout device must be 

manually reset by pressing the red button on the 

device. When the refrigerant pressure of the circuit 

falls below the switch limit, the cutout device 

contacts open, causing a shutdown alarm. The low 

pressure cutout device automatically resets when the 

fault condition is addressed. 


Part Number 474626

Air Flow Measuring Station (Universal Input 11) 

Measured by the either the Inlet cone sensor or AMD 

damper located in the outside air inlet. This is the 

actual air flow being measured in CFM as calculated 

by the factory calibrated air flow measuring station. 

View Only 

Primary Static Pressure Input (Universal Input 12) 

Displays the interpreted value of the voltage read 

from the space or duct static pressure sensor. The 

static pressure sensor should be field installed in the 

space/duct served by the rooftop unit. The output 

signal from the sensor must be 0-10 VDC. The space 

/ duct static pressure sensor, when used, must be 

connected to Universal Input 12 on the 34 point 

module depending on the configuration of the 

ventilator. For the sensor voltage to be interpreted 

correctly, the conversion scale and offset values must 

be set up correctly for that device (refer to the 

Appendix). 

Filter Status Input (Universal Input 13) 

The filter status differential pressure switch 

(optional) indicates the pressure across the filters. If 

the contacts close for five continuous minutes on the 

pressure switch, the controller interprets a dirty filter 

condition. The unit operates normally, but the alarm 

LED is illuminated on the controller. 

Space Setpoint Adjustment (Universal Input 14) 

Represents the amount of offset currently being 

applied to the space temperature setpoint. A positive 

value will increase the space temperature setpoint by 

the amount shown. A negative value will decrease the 

space temperature setpoint by the amount shown. 

Occupancy Input (Universal Input 15) 

The hardwired occupancy input of the controller can 

be used to determine the occupancy mode. When the 

input contacts are closed, the mode of the controller 

is occupied. When the contacts are open, the mode is 

unoccupied. The factory-installed jumper wire should 

be removed when a field-installed occupancy device 

is used. If the hardwired input is used to determine 

the occupancy of the controller, the OCC 

HARDWIRED field (operator interface or PC tool) 

should be set to TRUE. When the hardwired input is 

not being used to determine the occupancy, the OCC 

HARDWIRED field should be set to False 

Shutdown Input (Universal Input 16) 

The shutdown input of the controller prevents unit 

operation when the input contacts are open. The 

factory-installed jumper wire should be removed 

when a field-installed shutdown device is used. 


Secondary Static Pressure Input (Universal Input 1) 

When the unit is equipped with both a space and duct 

static pressure sensor, universal input 1 of the 16 

point module will always be used for the duct static 

pressure sensor input. For the sensor voltage to be 

interpreted correctly, the conversion scale and offset 

values must be set up correctly for that device (refer 

to the Appendix). 

Exhaust Temperature (Universal Input 2) 

Measured with a thermistor (type III) factory 

installed at the exhaust side of the heat wheel. The 

sensor is wired to Universal Input 2 on the expansion 

module of the controller. 

Pressure Sensor Circuit A (Universal Input 3) 

Measured with a pressure transducer factory installed 

in the refrigeration piping. The signal from the sensor 

will be a 0-10 VDC signal with a range of 0-750 psi. 

The sensor is wired to Universal Input 3 on the 

expansion module of the controller. 

Exhaust Fan Status (Universal Input 4) 

Reflects the status of the differential pressure switch 

for the exhaust fan (Universal Input 4, expansion 16 

point module). When the input contacts are closed, 

the exhaust fan status is true. When the input contacts 

are open, the exhaust fan status is false. 

CO2 Sensor (Universal Input 5) 

Measured by the field installed CO2 sensor located in 

the space/room served by the rooftop unit. That 

sensor provides a 0-10 VDC signal to the controller, 

Universal Input 5, of the expansion module that 

corresponds to the space CO2: 0 VDC = 500 ppm 

CO2, 10 VDC = 1500 ppm CO2. 

Fan / Damper Remote Command (Universal Input 6) 

Displays the fan speed command coming from the 

remote fan input, universal input 6 on the expansion 

16 point module. 0vdc will equal the units minimum 

supply fan speed, and 10 vdc equals the units 

maximum supply fan speed. 

Low Limit (Universal Input 7) 

Displays the status of the low limit sensor, when 

applicable (factory supplied with hot water coils). 

The ventilator will go into a low limit alarm, shutting 

down the fans, closing the outside air damper, and 

forcing the hot water valve open, any time the input 

is closed. Once triggered the low limit will be 

enabled for five minutes and then automatically reset. 

After three strikes the controller must be reset. Input 

open=normal, input closed=alarm.

Fan Speed Adjustment 

Each VPR, VPRE, VPRP and VPRX rooftop unit 

includes an variable frequency drive (VFD) for the 

supply section as well as the exhaust fan section 

(dedicated VFD for each). 

Supply Fan 

To modify the supply fan speed of a VPR, VPRE, 

VPRP or VPRX unit, the 0-10 VDC output signal to 

the VFD must be changed from within the JeneSys 

controller. 

1. Using the LCD display on the controller, go to 

the advanced setpoints menu. 

2. Using the PREV and NEXT buttons, move the 

underscore to the SUPPLY FAN SPEED and 

press (enter) on the keypad. 

3. Use the ◄ and ► (left and right) and ▲ and ▼ 

(up/down) arrows to move the cursor to the 

desired digit allowing the desired output to be 

entered (e.g., 95.4%). 

4. Press the enter button to save the change. 

Exhaust Fan 

The procedure to modify the exhaust fan speed (if 

equipped) is similar to adjusting the supply fan speed. 

However, note that the exhaust fan speed operates 

based on an offset from the supply fan speed. As a 

result, the parameter to adjust exhaust fan speed is 

listed as EF VFD OFFSET with an available 

adjustment range of -20% to +20%. To modify the 

EF VFD OFFSET parameter follow the instructions 

below.

IMPORTANT 

Changes to the supply fan speed parameter (SUPPLY 

FAN SPEED) will affect the speed of the exhaust fan 

as well. 

Verification 

With the changes made to the VFD parameter(s), 

confirm the VFD/fan speed by enabling the fan to 

operate. Upon startup, the fan should quickly ramp to 

the design speed. The speed (in Hz) is indicated on 

the front of the display. If the controller is sending a 

fan speed of 100%, fan speed analog output should 

be 10 VDC and the fan speed should be the design 

limit.

Occupancy 

Displays Occupied during the day (occupied hours), 

Unoccupied and night (unoccupied hours), and 

Standby (when unit is running in standby. The 

occupancy of the controller is determined by: 

• Hardwired occupancy input 

• Local time clock/schedule 

• Communicated command from building 

automation system 

When a hardwired occupancy input is used, remove 

the occupancy input jumper wire on Universal Input 

15. Connect the occupancy device to that input. The 

setup parameter for Occupancy Hardwired must be 

set to True. 

To use the units standby feature the Occupancy 

Hardwired must be left at false, occupied and 

unoccupied will be set via the units stand alone 

controller. When the stand alone schedule is occupied 

and the universal input 15 is open the unit will run in 

standby mode. When the stand alone schedule is 

occupied and the universal input 15 is closed the unit 

will run in occupied mode. When the stand alone 

schedule is unoccupied and the universal input 15 is 

either open or closed the unit will be in unoccupied 

mode. 

The occupancy can also be determined by the local 

time clock/schedule in the controller. When the local 

clock/schedule is used, set Occupancy Hardwired to 

False. Ensure that the time and date are set correctly 

in the controller. 

Finally, a communicated command from a building 

automation system (BAS) can be used to determine 

the occupancy of the controller. When a 

communicated command is to be used, set 

Occupancy Hardwired to False. Communication is 

possible via several communication protocols 

including LonTalk, BACnet IP, and BACnet MS/TP.

operation, the speed of the fan remains constant at the 

defined speed (50-100%, adjustable). At 100%, the 

fan speed is determined according to the setup of the 

VFD (the design frequency, in Hz). The speed of the 

supply fan may be slowed for constant volume 

operation by adjusting the supply fan speed in the 

controller (50-110%). The minimum speed must not 

be less than 50% of the design flow to ensure proper 

heating and cooling operation. 

For variable air volume (VAV) applications, the

Supply or Supply w/ Reset Control 

Allows the user to force the unit into supply air only 

mode. If the unit detects a space temperature sensor it 

will automatically switch from supply air only to 

supply air w/ reset mode. If supply air control is 

desired with a space sensor installed this point must 

be set to force supply only. In supply air temperature 

control, the unit attempts to control the supply air 

temperature at fixed heating and cooling setpoints 

(adjustable). In space temperature control with supply 

air temperature reset, the unit compares the space 

temperature to the space temperature heating setpoint

Lonworks 

Neuron 

The Neuron ID is a hardware address that will change 

if the hardware changes. Each LonWorks device has 

a unique 48 bit Neuron ID that was burnt into the 

Neuron chip when it was manufactured, resulting in 

approximately 300 trillion different combinations. 

The Neuron ID is broadcast through the network 

when a device is pinned so that a logical address 

(Subnet/Node ID) can be assigned. The network 

management tool must have the Neuron ID to 

commission a device. The Neuron ID does not 

contain information about the address of a device. A 

device’s Neuron ID and Subnet/Node ID can be 

found in the Identifiers tab of the device’s properties.

The occupancy can also be determined by the local 

time clock/schedule in the controller. When the local 

clock/schedule is used, set Occupancy Hardwired to 

False. Ensure that the time and date are set correctly 

in the controller. 

Finally, a communicated command from a building

Neuron 

The Neuron ID is a hardware address that will change 

if the hardware changes. Each LonWorks device has 

a unique 48 bit Neuron ID that was burnt into the 

Neuron chip when it was manufactured, resulting in 

approximately 300 trillion different combinations. 

The Neuron ID is broadcast through the network 

when a device is pinned so that a logical address 

(Subnet/Node ID) can be assigned. The network 

management tool must have the Neuron ID to 

commission a device. The Neuron ID does not 

contain information about the address of a device. A 

device’s Neuron ID and Subnet/Node ID can be 

found in the Identifiers tab of the device’s properties. 

See also Subnet/Node ID.

Service Pin 

The service pin generates a service-pin message that 

contains the Neuron ID and the program code 

identification of the node. A service-pin message is a 

network message that is generated by a node 

and broadcast on the network. It can be used to 

commission the LONWORKS network. Set to True 

to generate a service pin and the value will 

automatically be reset back to False.
