Installation and Configuration: Display Sensor
Wiring the Sensor
WARNING
Hazardous voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power cannot be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
NOTICE
Equipment damage!
Applying excessive voltage to the sensor will permanently damage it.
To wire the sensor to the unit controller:
1. Ensure that the wires are connected to the appropriate terminals at the unit controller.
2. Insert each wire into the appropriate location in the terminal block (see the table in Figure 1).
Tighten the terminal screw.
Note: The wire connections can be made while the terminal block is either on the circuit board,
or removed from it.
3. Perform a pull test to ensure that the wires are properly connected.
4. If the terminal block was removed from the circuit board, attach it to the pins inside the sensor
cover (Figure 1).
5. Push the excess wire into the wall cavity and plug it with nonflammable insulation to prevent
drafts from affecting the sensor.
Important: Do not coil excess wire inside the back plate.
