Description
Defines the minimum flow temperature.
Defines the maximum flow temperature.
The boiler switches off on the basis of the temperature set.
0 = Fixed: the switch-off temperature is fixed at the maxi-
mum value regardless of the value set on the control panel.
1 = Correlated: the boiler switches off according to the
temperature set.
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
(Par. 3.14 Solar panels coupling function).
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.
The boiler has an electronic timer, which prevents the burner
from igniting too often in central heating mode.
In central heating mode, the boiler performs an ignition
ramp in order to reach the maximum output set.
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.
0= Automatic: the display lights up during use and goes off
after 15 seconds of inactivity. In the event of an anomaly the
display "flashes".
1 = Off: the display is always off.
2 = On: the display is always lit up.
Establishes what the indicator 11 displays (Fig. 38).
"Summer" mode:
0: the indicator is always off
1: active pump displays the flow temperature, pump off the
indicator is off
"Winter" mode:
0: always displays the value set on the C.H. selector
1: active pump displays the flow temperature, pump off
always displays the value set on the C.H. selector
