P67
P67.1
In winter mode the pump is always powered and so functions
continuously.
P67.2
P67.2
In winter mode the pump is managed by the room thermostat or by the
remote control.
P67.3
In winter mode the pump is managed by the room thermostat or by the
remote control and by the boiler flow probe.
P68
0s ÷ 500s
The boiler is set to ignite the burner immediately after a request for
heating. In the case of particular systems (e.g. area systems with
motorised thermostatic valves etc.) it could be necessary to delay
switch-on.
0 seconds
P69
0s ÷ 255s
The boiler has an electronic timing device that prevents the burner
from igniting too often in the central heating phase.
180 seconds
P70
0s ÷ 840s
The boiler performs an ignition ramp to arrive from minimum power
to nominal heat output.
180 seconds
(3 minutes)
P71
P71.1
(-3°C)
The boiler ignites to heat the domestic hot water (when the boiler is
connected to an external storage tank) when the water contained in the
storage tank unit falls by 3°C with respect to the temperature set.
P71.2
P71.2
(-10°C)
The boiler ignites to heat the domestic hot water (when the boiler is
connected to an external storage tank) when the water contained in the
storage tank unit falls by 10°C with respect to the temperature set.

Relay 1 not used.
RELE1-1
RELE1-1
In a system divided into zones, relay 1 controls the main zone.
RELE1-2
The relay signals the intervention of boiler block ( Can be coupled to
an external signalling device, not supplied).
RELE1-3
The relay signals that the boiler is on in heating phase.
(Can be coupled with an external pump, not supplied).
RELE1-4
Controls the opening of an external gas valve in concomitance with an
ignition request of the boiler burner.
RELE1-5
In case the boiler pump needs to be replaced with a traditional pump at
fixed speed it is necessary to connect the new pump to the relay board.
RELE2
(optional)
RELE2-0
Relay 2 not used.
RELE2-0
RELE2-1
In a system divided into zones, relay 2 controls the secondary zone.
RELE2-2
The relay signals the intervention of boiler block ( Can be coupled to
an external signalling device, not supplied).
RELE2-3
The relay signals that the boiler is on in heating phase.
(Can be coupled with an external pump, not supplied).
RELE2-4
Controls the opening of an external gas valve in concomitance with an
ignition request of the boiler burner.
RELE2-5
Function not available in this boiler model .
RELE2-6
In case the boiler pump needs to be replaced with a traditional pump at
fixed speed it is necessary to connect the new pump to the relay board.
