Wire the utility pulse meter
Wire the utility pulse meter to the termination board input.
1. Route input wires into the termination module through a conduit
opening (Figure 12 on page 19) or the conduit box.
2. Connect the wires to the METER INPUT terminals on the termina-
tion board (Figure 14 on page 24).
3. Connect the other end of the wires to the pulsed-output contacts of
the electrical meter.
Wire the thermistor
The thermistor input is for a Trane outdoor air temperature sensor only.
The input cannot be used for any other purpose. Using wire that meets
the specifications listed in Table 6 on page 26, wire the thermistor to the
termination board input.
1. Route input wires into the termination module through a conduit
opening (Figure 12 on page 19) or the conduit box.
2. Connect the wires to the THERMISTOR terminals on the termination
board (Figure 14 on page 24).
3. Connect the shield to the ground terminal.
4. Connect the other end of the wires to the thermistor device.
IMPORTANT
Tape the shield at the sensor. Any connection between the shield and
ground will cause a malfunction.
Note:
The thermistor input is not polarity sensitive.
