Application Installation and Trouble Shooting Guide
Mini-Bus Multiplex System
INSTALLATION
Select a location for the Auxiliary Heater Fan Control that will minimize the heavy wiring, allow access for
servicing and some amount of ventilation. Typically, it will mount near the heater. Mount the module with four
#8 screws through the holes in the cover. Plug the power wires from the fan motor into J2. Ground the fan
motor.
Connect a three wire cable from J6 on the Master Module to J1 on the Aux. Heater Module. The wire
connecting pin 1 will carry the fan current and must be sized to safely carry the current of the fan.
If the control is to be used to operate a circulating pump, outputs from J2-2, J2-3, and J2-4 should be connected
together to feed power to the pump.
