What to do if Thermal Zone Heat Pump system will not operate?
- SSandra HughesAug 11, 2025
If your Thermal Zone Heat Pump system isn't working, check a few things: Make sure the power is connected and the system is turned on. Note that the system has a 3-minute delay to protect itself after being turned off. Also, verify that your circuit breaker is on and that 'TIMER ON' is not displayed on the LCD.
