REST FEATURE







The interior of the vehicle can continue to be heated with the engine switched OFF using the REST feature of the IHKA. The feature is activated by pressing the REST button on the IHKA control panel. When activated, the auxiliary water pump and blower motor are switched on. This feature will remain active for up to 15 minutes or until the coolant temperature drops below 30°C.


Switching ON requirements for the REST feature include:

- Ignition switched OFF or in KL R
- Rest button pressed
- Outside temperature < 15°C
- Coolant temperature > 70°C
- Battery voltage > 11.4 volts
- Less than 15 minutes after ignition is switched OFF

Switching OFF conditions for the REST feature include:

- Ignition switched ON - KL15
- Battery voltage < 11.4 volts
- Rest button pressed while system is ON
- Coolant temperature < 30°C

When the REST feature is activated in KL R, all of the IHKA functions are operable. This includes the blower speed, air distribution control and temperature settings.

With the ignition switched OFF the REST feature is in a preset operating mode. The blower fan runs at medium speed and the temperature is set to allow maximum heat.
