Page 9: Installation
Installation 1.1 Introduction Your Desert Aire controller is designed for precise monitoring and control of air temperature, relative humidity (RH) and Dew Point (DP) within a conditioned environment. This CM3570 control system is easy to install and operate. The controller itself is installed in the electrical cabinet of the dehumidifier and features an internal display terminal (IDT) and an optional remote display terminal (RDT).

Automatic reset alarms are alarms that allow the unit to return to operation once the operating parameter has been returned to acceptable operating conditions. The unit will restart automatically; however, the red alarm LED will remain illuminated until acknowledged, to alert the operator the alarm occurred.
Page 62 Zone Sensor Fault or Intake Sensor Fault This is an automatic reset alarm. Check the communication wiring to the sensor when this fault occurs. The red alarm LED on the display will stay lit until the alarm is reset. Pump Overload This is a manual reset alarm.
Page 63 3.11 CWC Temp, CWC Flow, or HWC Flow Valve Alarms These are manual reset alarms. The valve alarm is activated when the valve sees a fault condition. This can be a variety of different faults, and the valve diagnostics should be viewed to determine the exact fault.
Page 65 Zone, Intake Temperature, Relative Humidity and Dewpoint Sensor These sensors are communication devices which send Modbus data out from addresses 190, and 191. If communication is lost from this device, an alarm is activated. The Desert Aire replacement part numbers are available by calling our Service Department.
