  • Page 9: Installation

    1 Installation Introduction Your Desert Aire controller is designed for precise monitoring and control of air temperature and relative humidity (RH) within a conditioned environment. This CM3560 control system is easy to install and operate. The controller features an internal display terminal (IDT). This display allows viewing and adjustment of the unit’s sensors and setpoints.

  • Page 10: Unit Sensor Installation

    Auxiliary Air Heating Control Wiring Note: You must use the Desert Aire CM3560 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 the cooling mode.

  • Page 11: Auxiliary Heating - Proportional Signal

    1.3.2 Auxiliary Heating - Proportional Signal Desert Aire will provide a proportional 0-10 VDC direct-acting signal to modulate a heating coil control valve or other auxiliary modulating heater. Most proportional valves have either three (3) or four (4) terminals for field- installed wiring.
