Fuel driven parking heater
The user sets the desired start time using one of the two timer functions in the display on the combined instrument panel (driver information module) (5/1). The time is programmed by twisting the ring on the control stalk and by pressing the "reset" button for the desired time (timer 1, timer 2 or direct start). Direct start can also be used to start the heater.
The central electronic module (4/56) receives data about when the driver wants to drive from the control stalk module (steering wheel module) (3/130) and the combined instrument panel (driver information module).
The central electronic module calculates when the heater needs to start so that it is warm enough in relation to the outside temperature. Information about the temperature comes from the outside temperature sensor which is connected to the driver's or passenger door module.
The central electronic module calculates when the heater needs to start:
- The heater calculates when start is required (15-50 minutes before the intended departure at medium low temperatures between -10 °C and +15 °C)
- The run time of the heater is a maximum of 60 minutes at temperatures < -10 °C
- The running time of the heater is at least 15 minutes before the planned departure (Warm temperatures between +15 °C and +25 °C).
When the heater is started directly using the control stalk it runs until it is shut off or for a maximum of 60 minutes. The heater is on for 10 minutes after the set time to allow for the driver getting to the car late.
A text message is displayed in the driver information module when the heater is running.
