A112_A: Water Inlet Thermistor Failure
Status
This is an active alarm, the system will continue to operate.
Description
This alarm is currently unused and is reserved for an EcoNet enabled hydronic air handler in the future.
Cause
Moisture is condensing on the control board at the pins or solder pins where the water inlet sensor would connect.
Solution
1. Make sure control board is dry and cycle power to system to see if fault clears.
2. Determine cause of moisture building or accumulating on control board such as low airflow, or blow off from coil.
3. Determine source of moisture on control board.
4. If power cycle doesn't resolve issue, replace air handler control board.
