  • Page 9: Installation

    Installation 1.1 Introduction Your Desert Aire controller is designed for precise monitoring and control of air temperature and relative humidity (RH) within a conditioned environment. This CM3510 control system is easy to install and operate. The controller features an internal display terminal (IDT).

    1.3. Auxiliary Air Heating Control Wiring Note: You must use the Desert Aire CM3510 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.
