2.3 DEFAULT VALUES
The factory-set configuration provides for the following devices:
- ambient temperature probe
- ambient relative humidity probe
- outside air temperature probe
- water temperature probe
- cold water valve
- hot water valve
- all heaters enabled (n.2)
- both compressors enabled
- external humidifier
Here is the list of the default values the controller accepts as machine parameters
whenever the user answers affirmatively to the mask successive to that of back-up
memory deletion in the “special procedures” branch.
