t2 DHW thermostat
Establishes the boiler ignition and switch-off mode in DHW mode.
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 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)
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)

Central heating
ignitions timer
The boiler has electronic timing, which prevents the burner from igniting
too often in central heating mode

t6
Central heating
ramp timer
In the heating stage, the boiler performs an ignition ramp in order to reach
the maximum output set

t7
CH ignition de-
lay from TA and
CR request
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

t8 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.
0 - 2 0
t9 Display
Establishes what the indicator displays 14 (Fig. 2-1).
"Summer" mode:
0: the indicator is always off
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
1: circulator active, it displays the flow temperature
pump off always displays the value set on the CH selector
