Auxiliary Potentiometer
An auxiliary potentiometer can be connected to the HPC or HPC Plus at the
terminals labeled “Aux Pot.”
Step
Procedure
1
Connect the wiper wire to Terminal 1.
2
Connect the clockwise wire to Terminal 2.
3
Connect the counterclockwise wire to Terminal 4 at the “Temp
Sensor Input” label.
§
This connection allows adjustments to the zone setpoint.
Novar Controls Corporation’s Futura Temperature Sensor (Model (FTS-3A) can
be used with the HPC or HPC Plus to obtain setpoint adjustment. Installation
instructions are included with the sensor.
Temperature Sensor Inputs
The temperature sensor input terminals are located at the “Temp Sensor Input”
label. Each HPC or HPC Plus must use a Remote Temperature Sensor
(RTS-UVC) for discharge air
and
one of the following sensors:
§
UVC Wall-Mount Indoor Temperature Sensor (WTS-UVC)
§
Futura Temperature Sensor (FTS-3 or FTS-3A with temperature setpoint
adjustment)
§
RTS-UVC (for return air control)
Step
Procedure
1
Connect the Wall-Mount Temperature Sensor’s plus wire (+) to
Terminal 3.
2
Connect the Remote Temperature Sensor’s red wire to Terminal 5.
3
Connect the black wire (–) from both sensors to Terminal 4.
To wire the other sensors to the HPC or HPC Plus, refer to the installation
instructions shipped with the sensors.
NOTE! Maximum recommended sensor wire length for connecting
the temperature sensors to the HPC or HPC Plus is 100 feet
using 22-gauge wire (Novar Controls WIR-1010, Belden
8761, or equivalent).
