A: 1. Confirm that the temperature reaches the heating off value, the work indicator is off, but the heating output is not turned off.
- Check the power of the heating equipment (voltage and watt), too much power may lead to equipment damage;
Do you mean when the temperature reached heating target value, the work indicator of ITC-306A is off, but the heating outlets still on?
Could you please let me know the voltage and watt of the heater?
If the power of the heating device is within range and the built-in thermostat is OK, try the following steps:
Input Power: 100 ~240VAC, 50Hz/60Hz
Temperature Control Output: Max. 10A, 100V ~240V AC
Unplug the controller, plug heating devices.
Hold the SET button (don’ t loosen it till power-up)
Connect the power supply to power it on, then release the Set button (within 2 seconds, otherwise, it will enter normal mode)
Press the down button, Please do not press the up button. Are the heaters turned on? (within 2 seconds, otherwise, it will enter normal mode)
This is a test mode, it can check if there is a problem with the heating outlets.
