Auto/Off Switch

The automatic mode is activated with a single press of the AUTO switch; the green LED illuminating indicates this to the driver. The air distribution and blower speed is controlled automatically, and the air conditioning is switched on when AUTO is active.

The driver can over-ride the automatic mode of the air distribution or blower by pressing one of the distribution buttons or manually adjusting the blower speed. When the blower is being controlled in AUTO mode the blower speed bars and fan symbol are not displayed in the central display panel. In the automatic mode, if the temperature is set to LO or HI, the blower runs at maximum speed with correction only for vehicle speed.

The IHKA control panel may also be switched off by using the OFF horizontal rocker switch. This will switch off the blower and air conditioning, distribution control functions and temperature control will also be switched off.
