t2 DHW thermostat
Establishes the switch-off method in DHW mode.
1 and 3
Correlated: the boiler switches off according to the temperature
set.
0 and 2 Fixed: the switch-off temperature is fixed at the maximum value
regardless of the value set on the control panel.

t3
Solar delay
timing
The boiler is set to switch-on immediately after a request. for DHW In the
case of coupling with a solar storage tank positioned upstream from the boiler,
it is possible to compensate the distance between the storage tank and the
boiler in order to allow the water to reach the boiler. Set the time necessary
to verify that the water is hot enough (see par. Solar panels coupling)

t4
Domestic hot
water priority
timing
In winter mode the boiler, at the end of a domestic hot water request, is
ready to switch to central heating mode if there is an active request. Timing
sets a time period in which the boiler waits before changing the operating
mode, in order to quickly and comfortably satisfy an additional request for
domestic hot water.

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

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.

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
