P4
Pump func-
tioning
The pump can function in two ways.
0 intermittent: in winter "mode" the circulator is managed by the room
thermostat or by the remote control
1 continuous: in "winter" mode the circulator is always powered and is
therefore always in operation

External probe
correction
If the reading of the external probe is not correct it is possible to correct it
in order to compensate any environmental factors.

t2
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 neces-
sary to verify that the water is hot enough (see par. Solar panels coupling)
0 - 30 seconds

t3
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.

CH ignition
delay 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
