1. 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 dehumidier and features an internal display terminal (IDT)
and an optional remote display terminal (RDT). This display allows viewing and adjustment of
the unit’s sensors and set points. It also indicates the operating status of major components
inside the dehumidier.
Most sensors and devices have been factory-installed and wired inside the dehumidier. In
most cases, only connection to cold and hot water inlet/outlet pipes, electrical power
connection, and zone air sensors are required. Connection to the facilities computer network or
building management system may also be required.
The CM3570 controller features optional building automation access. This includes options for
network communication ability including BACnet IP, BACnet MS/TP, ModBus RTU and
ModBus IP.
1.2 Sensor Installation
The CM3570 control system requires a zone mounted combination relative humidity
and temperature sensor. Mount this sensor in the conditioned space away from any
hot spots but in an area that is representative of the zone. Constant air ow across this
sensor will help insure proper readings.
1.3 CM3570 Controller Overview
Desert Aire’s CM3570 microprocessor controller is a powerful, exible controller with
many useful features including
• Display of zone air conditions and refrigerant pressures.
• Display of equipment operating status such as dehumidication, cooling and
heating.
• Display of alarms for abnormal conditions such as sensor failures or tripped
safety controls.
• Remote setpoint option as well as lights on and lights o setpoints.
• A convenient, easy-to-understand display interface which allows the operator
to view and change setpoints and time schedules.

2. CM3570 Controller Details
2.1. Menu Overview and General Instructions
Your Desert Aire controller is pre-programmed and congured at the factory for use in the
application you have specied. The internal display terminal (IDT, see Figure 1) allows the
operator to monitor and adjust the setpoints of your Desert Aire system. The IDT has an LCD
screen and six keys. These keys are labeled as below:
The remote display terminal (RDT) has an LCD screen and six keys. These keys are labeled
as below:
The Home Screen (Figure 1) displays the Desert Aire logo and shows the dehumidier
programmed size, the actively used zone temperature and humidity sensor, and the unit
status. The right side of the display shows “Esc → Menu” which indicates that if the Esc key
is pressed, the Main Menu will be displayed. Pressing Esc on any other screen will take
you back one screen. The “Prg → Stpt” indicates that if the Prg key is pressed, the setpoints
can be changed. The “↑ ↓ → Help” indicates that if the UP or DOWN keys are pressed, the
help screens will be shown. The UP and DOWN keys will now scroll through the help screens.
Menu screens allow the user to select from a series of actions. The action that is capitalized on
the screen is selected by pressing the ENTER key. To cycle through the selections on a menu
screen, use the UP and DOWN keys.
If setpoints or selections can be altered on a screen, the ENTER key will cycle through those
items. Once the cursor is over an item, the UP and DOWN arrow keys will modify the setting.
Numeric values require that the ENTER key be pressed to accept the value. An “on” or “o”
selection is altered as soon as the UP or DOWN keys are pressed.
