Setback Temps - DD01E / DD01F
The DD01* and the DigiSmart™ control can be programmed for 3 different times to activate temperature setbacks. The
current factory default temperature setbacks in v2.5 * software release are: 2º from set point in 30 minutes, 3º in one
(1) hour, and 6º in three (3) hours. For each time, you can select a setback temperature. The amount of setback is the
amount of degrees the control will operate from guest’s setting in degrees F. If a change to the factory default temperature
settings is desired, use the following instructions.
NOTE: When first entering the configuration mode, if you see “ - - ” then you have version 2.5 or higher.
You can verify the software version by starting with the unit in the OFF position, and while holding down the
“+” and “-” buttons , double click the COOL button and then release and push the FAN button within one
second. The unit display will scroll through all of the thermister temperatures and the last item displayed
will bs CS (current software) and you will see 25 for v2.5.
*Other software versions may have different factory setback defaults. Contact your PTAC representative to
determine factory default settings.
