The antifreeze system does not work when the power and/or gas to the unit are turned
off. To avoid damage caused by freezing during long idle periods in winter, it is advisable
to drain all water from the boiler, DHW circuit and system; or drain just the DHW circuit
and add a suitable antifreeze to the heating system, complying with that prescribed
insec. 3.3.
2.4 Adjustments
Summer/Winter Switchover
Press the summer/winter button (detail 6 - fig. 1) for 2 seconds.
The display activates the Summer symbol (detail 10 - fig. 1): the boiler will only deliver
domestic hot water. The antifreeze system remains activated.
To deactivate the Summer mode, press the summer/winter button (detail 6 - fig. 1)
again for 2 seconds.
Heating temperature setting
Use the heating buttons (details 3 and 4 - fig. 1) to adjust the temperature from a min. of
30°C to a max. of 85°C; it is advisable not to operate the boiler below 45°C.
DHW temperature adjustment
Use the DHW buttons (details 1 and 2 - fig. 1) to adjust the temperature from a min. of
40°C to a max. of 50°C.
Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature required in the rooms. If the room ther-
mostat is not installed, the boiler will keep the system at the set system delivery setpoint
temperature.
Room temperature adjustment (with optional remote timer control)
Using the remote timer control, set the required temperature in the rooms. The boiler will
adjust the system water according to the required room temperature. For operation with
remote timer control, please refer to the relevant instruction manual.
ECO/COMFORT selection
The unit has a function that ensures a high domestic hot water delivery speed and max-
imum comfort for the user. When the device is activated (COMFORT mode), the water
contained in the boiler is kept hot, thereby ensuring immediate availability of hot water
on opening the tap, without waiting times.
The user can deactivate the device (ECO mode) by pressing the eco/comfort button
(detail 7 - fig. 1). In ECO mode the display activates the ECO symbol (detail 12 - fig. 1).
