Standby mode of the parking heater
If the heater goes to standby mode after installing the heater, it is important to pay attention to two points to solve this problem:
1) At what temperature do we set the parking heater switch?
2) We must pay attention to how the heater works, the heater uses a temperature sensor that displays the temperature to find out what temperature it is, for example, you set it to 20 degrees, but you did not leave the back of the heater empty during installation. And the air flow cannot circulate, in this case the heater will be wrong, the heater only understands the temperature behind the heater and does not recognize the temperature inside the cabin.
