The Blower Control Module (BCM) is used to operate the OEM fan blowers in the vehicle by the use of pulse width modulation (PWM). The benefit of using the BCM with the Espar Hydronic heater is to preheat your cabin at the same time you are preheating your coolant. This will allow for a warm cabin area and defrosted windows before starting your engine. The BCM will allow extended use of the vehicle’s blower fan with substantially less amp draw on the battery compared to similar systems.
