P66
P66/C
With the external probe present it defines at which minimum external
temperature the boiler must operate at the maximum flow temperature (see
graph Fig. 1-8) (can be set between -20°C and 0°C)
N.B.:
to continue one must confirm the parameter (press “D” or exit adjust-
ment “P66” by pressing “C”)
-5°C
P66/D
With the external probe present it defines at which maximum external
temperature the boiler must operate at the minimum flow temperature (see
graph Fig. 1-8) (can be set between 5°C and +25°C)
N.B.:
to continue one must confirm the parameter (press “D” or exit adjust-
ment “P66” by pressing “C”)
25°C
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 central
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
(-2°C)
Boiler ignition for heating the domestic hot water occurs when the water
contained in the cylinder falls by 3°C with respect to the temperature set.
Solar function deactivated
P71.1
P71.2
(-5°C)
Boiler ignition for heating the domestic hot water occurs when the water
contained in the cylinder falls by 10°C with respect to the temperature set.
Solar function active, if the input domestic hot water has a sufficient tempe-
rature the boiler does not switch on
P72
AUTO
OFF
9L/M
12L/M
15L/M
This function does not affect the correct functioning of this boiler model.
AUTO
RELAY1
(optional)
RELE1-0
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 a boiler block (Can be coupled to an
external signalling device, not supplied)
RELE1-3
The relay signals that the boiler is on and in the heating stage
(Can be coupled with an external circulator 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 the event the boiler circulator pump is replaced with a traditional fixed
speed circulator pump one must connect the new circulator pump to the
relay board.
RELAY2
(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 and in the heating stage
(Can be coupled with an external circulator pump, not supplied)
RELE2-4
Controls the opening of an external gas valve in conjunction with an ignition
request of the boiler burner
RELE2-5
Function not available in this boiler model
RELE2-6
In the event the boiler circulator pump is replaced with a traditional fixed
speed circulator pump one must connect the new circulator pump to the
relay board.
