DHW thermostat
Establishes the ignition and switch-off method of the boiler in DHW phase
(when the boiler is
connected to an external storage tank unit).
0 - Ignition occurs when the water contained in the storage tank drops by 3°C with respect to the
temperature set and switches off when the temperature is at the value set (solar activated)
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)
3 - Ignition occurs when the water contained in the storage tank drops by 5°C with respect to the
temperature set and switches off when the temperature is at the value set (solar activated)

The boiler is set to switch-on immediately after a request. In the event of particular systems (e.g.
area systems with motorised thermostatic valves etc.) it may be necessary to delay ignition

Display lighting
Establishes the display lighting mode.
0 Automatic:
the display lights up during use and dims after 15 seconds of inactivity. In the event
of an anomaly the display flashes.
1 Low:
the display is always lit with low intensity
2 High:
the display is always lit with high intensity.

Display
Establishes what the indicator displays 14 (Fig. 2-1).
"Summer" mode:

1: circulator active, it displays the flow temperature
pump off the indicator is off
"Winter" mode:
0: it always displays the value set on the central heating selector
