Description
Establishes the boiler ignition and switch-off mode in DHW mode.
0 - Ignition occurs when the water contained in the storage tank drops
by 7°C with respect to the temperature set and switches off when the
temperature is at -4°C with respect to the value set (solar deactivated)
1 - Ignition occurs when the water contained in the storage tank drops
by 2°C with respect to the temperature set and switches off when the
temperature is at +1°C with respect to the value set (solar deactivated)
2 - Ignition occurs when the water contained in the storage tank drops
by 10°C with respect to the temperature set and switches off when
the temperature is at the value set (Solar activated)
The pump can function in two ways.
0 intermittent: in winter "mode" the circulator is managed by the room
thermostat or by the remote control
1 continuous: in "winter" mode the circulator is always powered and is
therefore always in operation
