2.9 Auxiliary Heating Control Wiring
Note: You must use the Desert Aire control system to control or interlock with the room heating system.
This prevents wide fluctuations in room air temperature. It also prevents the heater from trying to heat
the room while the dehumidifier is running in cooling.
Desert Aire will provide a signal to operate the auxiliary pool room heating system. The signal can either
be a binary dry contact closure or a proportional voltage with an optional dry contact closure to operate
an interlock or pump. The heating output type is pre-set from the factory based on the request at the time
of order.
2.9.1 Auxiliary Heating – Dry Contact Closure
Desert Aire will provide a dry contact closure to interlock with the building heating system. This
contact closure is normally used to interlock with a gas or electric duct heater which has its own
power supply transformer. When the room air temperature drops below the set point, the dry
contact will close to energize the auxiliary heater. See the dehumidifier wiring diagram for details.
