Desert Aire - CM35xx Quick Start Guide
Main Menu
Pressing the Esc key from the Home Screen displays the MAIN MENU and allows for
the listed screens to be selected. The unit setpoints can be selected for adjustment
from this screen as well as the Temporary Occupancy Screen, the Occupancy
Schedule Screen and the Unit Revision Screen. In some cases a Status Screen will be
displayed which allows for viewing the status of the unit and viewing the sensor data
on the unit. If the Status Screen is not shown here, see the SERVICE MENU, Section
3.7, for Status Screen access.
Unit Status
Selecting the Unit Status will display most controller data either directly or by
selecting the appropriate screen. The unit mode is typically shown on the Status
Screen, which will indicate one of six possibilities. The unit can either require heating,
cooling or be satisfi ed. If the humidity in the zone is high, then heating/dehum, dehum
or cooling/dehum could be displayed.
Setpoints
A selection on the MAIN MENU will allow for the setpoints to be altered. Selecting this
screen will allow the supply air temperature, zone temperature, zone humidity or pool
temperature setpoints to be modifi ed, depending on the unit. Refer to Section 3. for
setpoint modifi cation instructions.
Temporary Occupancy
This screen allows the operator to set the unit into occupied mode for a preset amount
of time. Press the ENTER key and enter in the hours and minutes you would like the
unit to be temporarily in the occupied mode. When the cursor is blinking over the
"Press Prg to set" message, pressing the Prg key will override the schedule and allow
the unit to be temporarily occupied. The screen will now show "Override On." To clear
this occupied override, set the hours and minutes to zero and press the ENTER key.
The screen will now show "Override Off." Use this option for forcing an occupied
condition during an irregular occupied period or for troubleshooting. For
troubleshooting purposes, you may need to force the unit into the unoccupied mode.
Refer to Section 3.5 to turn the Occupancy Schedule off and ensure that the digital
input is not closed, forcing remote occupancy. Also, if the BMS has set the unit to the
occupied mode, this must be turned off to force the unoccupied mode.
Occupancy Schedule
Selecting the SCHEDULE SETUP from the MAIN MENU takes you to the
OCCUPANCY SCHEDULE MENU. This menu allows you to access and adjust the
Schedule Options, Temporary Holidays, Annual Holidays and Time settings. Detailed
instructions for these screens are as follows.
