ITC308 can’t get the temperature required to hold

Hello,
Before using the ITC-308-WIFI, please quickly check the following:

  1. Does the heater automatically turn on and heat to the target temperature after being powered on? Please understand that the actual heating temperature is determined by the heater itself.

  2. Does the heater have a built-in temperature controller? Please understand that this may affect the control of the ITC-308-WIFI.

  3. The heater’s power is within the range of 100-240V, 10A.

Regarding the ITC-308-WIFI, please also check if its settings are correct.
