What to do if Honeywell STT750 SmartLine Transmitter shows Electronics Module Fault?
If your Honeywell Transmitter indicates an Electronics Module Fault, try cycling the power to the transmitter. If the problem persists, it indicates a critical failure, and you should replace the Electronics Module.
What to do if Honeywell STT750 SmartLine Transmitter shows Temperature Sensor Comm Fault?
If your Honeywell Transmitter displays a Temperature Sensor Comm Fault, cycle the power to the transmitter. If the issue continues, replace the Temperature Sensor Module.
How to fix Temperature Sensor Module Fault on Honeywell STT750 SmartLine Transmitter?
If the diagnostic status indicates an input problem such as burnout or out of range, first correct the underlying error. Then, cycle the power to the Honeywell transmitter. If the Temperature Sensor Module Fault persists, replace the Temperature Sensor Module.
