Description
This establishes the ignition and shutdown mode
of the appliance in DHW mode.
It is enabled when the water in the storage tank
goes below the DHW set value and is disabled
when the temperature exceeds the DHW set value
The generator 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
product, it is possible to compensate the distance
between the storage tank and the generator in
order to allow the hot water to reach the heat
generator. Set the time necessary to verify that the
water is hot enough (see par. Solar panels
coupling)
In winter mode the heat generator, 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 heat
generator waits before changing the operating
mode, in order to quickly and comfortably satisfy
an additional request for domestic hot water
The hydronic module has an electronic timer,
which prevents the generator from igniting too
often in central heating mode
In the heating stage, the heat generator performs
an ignition ramp in order to reach the maximum
output set
The system is set to switch on immediately after a
request for room air conditioning. For special
systems (e.g. zone systems with motorised valves,
etc.), it may be necessary to delay ignition.
Establishes the display lighting mode.
AU: the display lights up during use and dims after
15 seconds of inactivity, in case of anomaly the
display works in flashing mode.
OFF: display lighting is always off.
ON: display lighting is always on.
Establishes what the indicator displays 14 (Fig. 12).
"Summer" mode:
ON: active circulator, this displays the flow
temperature, with circulator off the indicator is off
OFF: the indicator is always off
"Winter" and "cooling" mode:
ON: active circulator, this displays the flow
temperature, with circulator off the set value is
displayed on the central heating selector
OFF: this always displays the value set on the
central heating selector
