Desert Aire - LC/LV Manual
2.6.2 Wire and Fuse Sizing
The field-installed power supply wires and over current protection devices must be
sized to handle the minimum amperage of the dehumidifier without exceeding the
maximum fuse size rating. Both the minimum ampacity and the maximum fuse size
are printed on the unit rating plate.
2.7
Controls and Sensors
The standard Desert Aire LC and LV Series dehumidifiers are controlled by the CM3530 microprocessor
controller. This controller is designed for precise monitoring and control of air temperature and relative
humidity (RH) within a conditioned environment. The microprocessor has the option for a wall mount sensor
or a duct mount sensor. A separate controls manual has been provided. Refer to this separate manual for
controller and sensor specifications, operation, and options.
2.7.1 Wall Mount Sensor
If your dehumidifier was ordered with a wall-mount humidity and temperature sensor,
mount the sensor about five feet above the pool deck on an interior wall with natural
air circulation. Avoid the following locations:
•
Hot spots near concealed heating pipes, warm air ducts, supply register
outlets, or solar radiation.
•
Cold spots due to a cold wall or drafts from stairwells, doors, windows, or
supply
register
outlets.
•
Dead spots such as behind doors or in corners where room air cannot
circulate
freely.
2.7.2 Duct Mount Sensor
The duct-mount sensor is normally used in applications where continuous blower
operation is desired. A duct-mount sensor helps ensure consistent conditions
throughout the space. A drawback to this sensor is that it relies on a continuous
stream of air moving past it. Using a duct-mount sensor with a non-continuous blower
may lead to short-cycling of the refrigeration compressor. Install the duct-mount
sensor in the return air duct.

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.
2.8.1 Auxiliary Heating – Dry Contact Closure
Desert Aire provides 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
