speed level 6, press and release the Fan button to turn off the fan. Turning on the control will revert the fan to the Automatic
Mode or the last selected manual fan setting.
Cycled or Continuous Fan Operation
The fan can be set to run continuously whenever the system is turned on, or it can be set to cycle on and off with the
compressor. To change this fan operational setting, select either “CYC” or “con” in P-14. When “CYC” is selected, the setting
has been changed to cycled. When “con” is selected, the setting has been changed to continuous.

Use Program Mode to adjust operating parameters for your particular needs. Program Mode is also used to fine-tune the
system for the most efficient operation within an installation. (Variables such as ducting, sensor location, and system layout
affect system operation.) The control has factory default settings stored in permanent memory that can be recalled. However,
reprogrammed settings can be saved as the new default, thus overwriting the factory defaults. See “P-17: Reset Memorized
Defaults” on page 9 for details.

You can only enter Program Mode from the Off Mode. If necessary, press the Power button to enter Off Mode. Press and hold
the Power button while in the Off Mode until the letter “P” appears in the display. The characters “P1” followed by the P-1
parameter setting appear in the display. The control is now in the Program Mode. If no programming is attempted for one
minute, the control exits Program Mode and returns to Off Mode.

Press the Power button once to exit Program Mode and return to Off Mode. Or, do not attempt any programming for 50
seconds, then the control exits Program Mode and returns to Off Mode. Any programming changes made while in Program
Mode will be saved and put into operation after exiting Program Mode and returning the control to the On Mode. (If you want the
programming changes to become the new defaults, see “Memorizing New Program Parameters” below.) When you exit
Program Mode the software version number (such as “A24”) appears in the display.

While in Program Mode, press and release the Fan button to increment from one program parameter to the next until you reach
the desired parameter number. The programmable parameters range from P-1 through P-22.
When you reach the desired parameter number, use the Up and Down buttons to select the data or set the desired limits for the
parameter being programmed. See Table 2 on page 10 for a list of the parameters, the possible settings for each, and their
factory default settings.

If you want new parameters to be the program defaults, adjust the parameters to the desired settings, then press the Up and
Down buttons simultaneously while in Program Mode. This memorizes the new settings as program defaults and exits the
Programming Mode.
To return to the factory default settings, refer to the factory defaults listed in Table 2 on page 10 and reset the parameters
manually.

You can restore the last memorized default settings by entering Program Mode and setting P-17 to “rSt”. The memorized default
settings are restored and the control returns to Off Mode. See “P-17: Reset Memorized Defaults” on page 9 for details. To return
to the factory default settings, refer to the factory defaults listed in Table 2 on page 10 and reset the parameters manually.

The control’s software version (such as “A24”) appears in the display for one second prior to exit from Program Mode, then the
control returns to Off Mode.
NOTE
If you have any reason to contact Dometic about the system or programming the control, you must have the software
identification number and air conditioning unit serial number available. The serial number may be found on the
dataplate label.
