Coding Variants For Control Panel Functions

Hot-climate version. When this version is coded the recirculated air function (if active) it is saved to memory (EEPROM) along with the other data when the control module enters sleep mode and is immediately available the next time the engine is switched on.
Off lock. When this version is coded the OFF function is deleted when the control module enters sleep mode, the next time the engine is switched on the functions active before the OFF button was pressed are automatically reactivated.
Automatic variants and automatic air stratification. The IHKA offers three variants for handling the AUTO function. There are also three different modes of setting air stratification to 50% when the AUTO function is switched on.
