7. Операция
The heater control valve operates automatically in conjunction with your vehicle's climate control system. When you adjust the temperature setting inside your vehicle:
- For Heat: The climate control system sends a signal to the heater control valve, opening it to allow hot engine coolant to flow through the heater core. Air passing over the hot heater core is warmed and then directed into the cabin.
- For Cooling/No Heat: The climate control system signals the valve to close, restricting or stopping the flow of hot coolant to the heater core. This prevents unwanted heat from entering the cabin, allowing the air conditioning system to cool the air effectively.
Ensure your vehicle's climate control system is functioning correctly to allow the heater control valve to operate as intended.
