Cooling Fan

The condenser on the A/C systems interfaces with the EMS2000 over the bus network for electric fan operation. The electric fan is not directly controlled by the A/C system. The EMS2000 controls the fan via two relays.

This provides additional airflow through the radiator and condenser, when needed. The additional airflow allows more heat to be taken away from the condenser and thus allowing better cooling of the refrigerant.
