1. What should I do if the power indicator light on the thermostat is not lit?
If this occurs, first check if the main heating valve is closed. Then, check if the thermostat switch is turned on. If the main valve is closed and the thermostat switch is on, but the power indicator light is still not illuminated, it indicates a faulty thermostat or a connection issue.
2、The temperature controller power indicator is lit, but the heating light remains off. Is this normal?
If this occurs, you can adjust the thermostat knob to the highest temperature and wait approximately 40 seconds to see if the indicator light illuminates. If the indicator light remains off and there are no obvious heat sources around the thermostat, it indicates that the thermostat is faulty or there is another issue.
3、Is the heating light on the temperature controller always on?
If this situation occurs, you can adjust the thermostat control knob to the lowest setting and wait approximately 40 seconds to see if the heating indicator light illuminates. If the indicator light remains on and the temperature around the thermostat is significantly higher than the set temperature, it indicates a thermostat malfunction or other issue.
4、How to determine if the temperature controller is functioning accurately?
You can measure the temperature around the thermostat using a thermometer and then adjust the control knob to a slightly higher temperature. The heating indicator light should then illuminate. If the control knob is adjusted to a temperature lower than this, the heating indicator light should turn off. Please note that, in general, thermostats have a certain degree of variation in their control, but this variation will not exceed 1°C and will not affect normal use.
5. Does the heating indicator light on the thermostat flicker on and off, and is this normal?
If the system operates in this manner, it indicates that your heating system is functioning correctly.
6、When the temperature controller trips unexpectedly after being turned on, what could be the cause?
If this occurs, please contact customer service personnel promptly to investigate the cause.
7. The temperature control unit's heating indicator light is always on, but there is no feeling of warmth in the room. What should I do?
