Default
P0 DHW thermostat
Establishes the switch-o method in DHW mode.
1 Correlated: the boiler switches o according to the temperature set.
0 Fixed: the switch-o temperature is xed at the maximum value regardless of the value
set on the control panel.

P1
Solar delay
timing
e boiler is set to switch-on immediately aer 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)
0 - 30 seconds 0
P2
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

P3
Relay 1
(optional)
e boiler is set-up for functioning with the relay P.C.B. (optional), which can be
congured
0 = O
1 = Main zone control
2 =General alarm
3 = CH phase active
4 = External gas valve power supply
5 = Aquaceleris PTC control (Do not use on this boiler model)
0 - 5 0
P4
Relay 2
(optional)
e boiler is set-up for functioning with the relay P.C.B. (optional), which can be
congured
0 = O
1 =General alarm
2 = CH phase active
3 = External gas valve power supply
4 = Secondary zone control (from TA on relay P.C.B. contact)
0 - 5 0
P5
Relay 3
(optional)
e boiler is set-up for functioning with the relay P.C.B. (optional), which can be
congured
0 = O
1 = Chiller remote activation
2 =General alarm
3 = CH phase active

t0
Central heating
ignitions timer
e boiler has electronic timing, which prevents the burner from igniting too oen in
central heating mode

t1
Central heating
ramp timer
In the ignition phase, the boiler performs an ignition ramp in order to arrive at the
maximum power set

t2
CH ignition de-
lay from TA and
CR request
e boiler is set to switch-on immediately aer a request. In the case of particular sys-
tems (e.g. area systems with motorised thermostatic valves etc.) it may be necessary to
delay ignition.

t3 Display lighting
Establishes the display lighting mode.
0 Automatic: the display lights up during use and dims aer 15 seconds of inactivity. In
the event of an anomaly the display ashes.
1 O: the display is always lit with low intensity
2 On: the display is always lit with high intensity.
0 - 2 0
t4 Display
Establishes what indicators 17 and 21 display (Fig. 2-1).
0 Indicator 17: displays the set DHW setting;
Indicator 21: in winter mode it displays the set CH setting, while the indicator is switched
o in summer mode
1 Indicator 17: it is switched o in the presence of a request. Without any request the
indicator shows the set DHW setting.
Indicator 21: in the presence of a request, it shows the instant ow temperature of the
boiler. Without any request in summer mode, the indicator is o. In winter mode it
shows the set CH setting.
