The IDT, Figure 2, allows the operator to monitor the operation and adjust the setpoints of the
Desert Aire dehumidifi er. The IDT has an LCD screen and 6 keys. The keys on the top row are
the ALARM key shown as an alarm bell, PROGRAM key abbreviated “Prg” and the ESCAPE key
abbreviated “Esc.” The keys on the bottom row are the UP key shown as an up arrow, the
DOWN key shown as a down arrow and the ENTER key shown as a left arrow.
The Home Screen will display the Desert Aire logo and the dehumidifi er type in the upper right.
Below it, “Esc

Menu”, indicates that if the Esc key is pressed, the MAIN MENU will be displayed.
On any other screen, pressing Esc will take you back one screen. The bottom two rows will
display the specifi c unit data which might include occupancy status and zone conditions.
Menu screens allow the user to select from a series of actions. The action that is capitalized on
the screen will be selected when the ENTER key is pressed. 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 will require that the ENTER key be pressed to accept the value. An ‘on’ or ’off’
selection will be altered as soon as the UP or DOWN keys are pressed.
To view the alarms from any menu, simply press the ALARM key. The UP and DOWN keys will
show any active alarm. Any time an alarm is triggered, the red LED behind the ALARM key will
light. This LED will remain on until the alarm is acknowledged. Alarm acknowledgement and
history instructions are shown on the main Alarm Screen. To escape from the alarm screens,
press the Esc key.
Screens which display a small up arrow in the upper right and a small down arrow in the lower
left are part of a series of screens which can be accessed by pressing either the UP or DOWN
arrow keys. If the operator has not pressed a key for a while, the remote terminal will return to
the Home Screen.
