Troubleshooting
The CO
2
transmitter is not field repairable. In the event
the unit is not functioning properly, identify the
symptoms and determine a solution:
1. Verify that the unit is mounted properly.
2. Verify that all wiring is correct.
3. Verify that the power supply voltage level is
20 to 30 VAC or 18 to 30 VDC.
If the CO
2
transmitter does not operate after
completing these steps, replace the unit.
Repair Information

2
and
Temperature Transmitters fail to operate within their
specifications, replace the units. For a replacement
CO
2
transmitter, contact the nearest
