Off Mode

When the OFF blower setting is selected on the front auxiliary HVAC control assembly, the switch creates an open circuit within the front auxiliary HVAC control assembly. This prevents any output being provided by either the front or rear auxiliary HVAC control assembly. If the OFF blower setting is selected on the rear auxiliary HVAC control assembly, the switch will create an open within the rear auxiliary HVAC control assembly. This prevents any output being provided to the auxiliary blower motor, as long as the front auxiliary HVAC control assembly is in the OFF position. The front auxiliary HVAC control assembly controls the rear auxiliary HVAC control assembly on the auxiliary blower motor switch control circuit.
