Power supply on then blower fan motor on but thermostat not working

If the thermostat is not working while the power supply and blower fan motor are on, the issue could be a system fault or the thermostat may be halted. You can try using the RESET function by inserting a pin into the reset button hole (button ⑤) until a click is heard, then release it. After resetting, switch on the thermostat and observe its operation. If problems continue, it may require service or warranty support.
