P4
Pump function-
ing
e 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.

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.

Central heating
ignitions timer
e boiler has electronic timing, which prevents the burner from igniting

CH ignition de-
lay from TA and
CR request
e boiler is set to switch-on immediately aer a request. In the event of
particular systems (e.g. area systems with motorised thermostatic valves
etc.) it may be necessary to delay ignition

t7 Display lighting
Establishes the display lighting mode.
0 : the display lights up during use and lowers aer 15 seconds of inactivity.
In the case of anomaly the display ashes.

"Winter" mode:
0: always displays the value set on the CH selector
1: pump active displays the ow temperature,
pump o always displays the value set on the CH selector
