Default
P0 DHW thermostat
Establishes the switch-o method in DHW mode.
0 Fixed: the switch-o temperature is xed on the maximum value independently from
the value set on the control panel.
1 Correlated: the boiler switches o on the basis of the temperature set.
0 - 1 1
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
functioning
e pump can function in two ways.
0 intermittent: In winter “mode” the pump is managed by the room thermostat or by the
remote control
1 continuous: In “winter” mode the pump is always powered and so functions continuously

P3
Relay 1
(optional)
e boiler is set-up for functioning with the relay board (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

Relay 2
(optional)
e boiler is set-up for functioning with the relay board (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 board contact

P5
Relay 3
(optional)
e boiler is set-up for functioning with the relay board (optional), which can be
congured
0 = O
1 = Chiller remote activation
2 =General alarm
3 = CH phase active
4 = External gas valve power supply
5 = Aquaceleris PTC control (To be used on this boiler model if a three relay board is
installed)

t0
Central heating
ignitions timer
e boiler has electronic timing, which prevents the burner from igniting too oen in
central heating mode
0 - 600

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 sy-
stems (e.g. area systems with motorised thermostatic valves etc.) it could be necessary
to delay switch-on
0 - 600
seconds
0
t3 Display lighting
Establishes the display lighting mode.
0 Automatic: the display lights up during use and lowers aer 15 seconds of inactivity. In
the case of 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 set;
Indicator 21 in winter mode shows the set CH set, the indicator is o in summer mode
1 Indicator 17 is o in the presence of a request. Without any request the indicator shows
the set DHW set.
In the presence of a request indicator 21 shows the instant ow temperature of the boiler.
Without any request in the summer mode, the indicator is o. In winter mode it shows
the set CH set.
