Symptoms
Temperature has fallen below the minimum operating threshold. The system has shut down to prevent freeze damage or inefficient operation.
Possible Causes
- Insufficient heat input or excessive heat loss
- Flow restriction reducing heat transfer
- Temperature sensor reading incorrect value
Troubleshooting Steps
- Step 1: Verify actual temperature with an independent measurement
Temperature confirmed below threshold - Step 2: Check flow rates and heat source operation
Flow and heat input verified adequate - Step 3: Inspect temperature sensor for correct calibration
Sensor reading matches actual temperature
How to Reset
To reset: Restore normal temperature conditions and clear the alarm.
