Wiring & Termination
Carrier recommends using twisted pair of at least 22AWG and sealant filled connectors for all wire connections. Larger gauge wire
may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes. Do NOT run this device’s
wiring in the same conduit as high or low voltage AC power wiring. Tests show that inaccurate signal levels are possible when AC
power wiring is present in the same conduit as the sensor wires.
Diagnostics
Problems:
Controller reports higher or lower
than actual temperature.
Possible Solutions:
-
Confirm the input is set up correctly in the front end software
-
Check wiring for proper termination and continuity (shorted or open).
-
Disconnect wires and measure sensor resistance and verify the “Sensor” output is correct.
