DIP-SWITCH CONFIGURATION
SETTINGS
To be done in the installation phase, only by expert personnel.
Some functions are not compatible with each other and, for
this reason, limits to Dip-Switch configurations have been set.
By turning on or off Dip-Switches inside the thermostat, we
get the following functions:
Sw1 Dip 1 (Default OFF )
Water valve fitted:
- Present, set (ON).
- Absent, set (OFF).
Sw1 Dip 2 (Default OFF )
Position of the water temperature probe:
- Water temperature probe positioned up line from the valve,
set (ON).
- Water temperature probe positioned down line from the
valve, set (OFF).
Sw1 Dip 3 (Default OFF )
Water valve management:
- Optimised, set (ON).
heating mode: valve closure delayed compared to the
turning off of the ventilation;
cooling: valve closure earlier than the turning off of the
ventilation.
- Normal, set (OFF).
Sw1 Dip 4 (Default OFF )
Probe adjustment:
- Fixed adjustment, set (ON).
- Dynamic correction, set (OFF),
calculated on the basis of the water temperature.
NOTES:>
