The HVAC control module is a device that interfaces between the operator and the HVAC system to maintain air temperature and distribution settings. The battery positive voltage circuit provides power that the control module uses for keep alive memory (KAM). If the battery positive voltage circuit loses power, then all HVAC settings will be erased and reset at battery reconnect. The ignition 3 voltage circuit provides a device on signal. The control module supports the following features:
