Description
In winter mode the circulation pump is always powered and therefore always
functions
In winter mode the circulation pump is managed by the environmental ther-
mostat or the remote control
In winter mode the circulation pump is managed by the environmental ther-
mostat or the remote control and by the boiler delivery probe
The boiler is set to switch on the burner immediately after a request for envi-
ronmental heating. In the case of particular plants (e.g. plants with areas and
motorised valves etc) it may be necessary to delay ignition
The boiler has an electronic timing device that prevents the burner from
igniting too often in the heating phase.
The boiler performs an ignition ramp to arrive from minimum power at the
nominal heating power
Boiler switch-on for heating domestic water occurs when the water contained
in the cylinder falls by 3°C with respect to the set temperature
Boiler switch-on for heating domestic water occurs when the water contained
in the cylinder falls by 10°C with respect to the set temperature
This function has no effect on the correct functioning of this boiler model
Relay 1 not used
In a plant divided in areas, relay 1 controls the main area
The relay signals the intervention of a boiler block (can be combined with an
external indicator, not supplied)
The relay signals that the boiler is on
(can be combined with an external indicator, not supplied)
Controls the opening of an external gas valve in concomitance with a switch-on
request of the burner in the boiler
Relay 2 not used
Relay 2 activates the remote filling electrovalve (Optional). The command is
remote control.
The relay signals the intervention of a boiler block (can be combined with an
external indicator, not supplied)
The relay signals that the boiler is on
(can be combined with an external indicator, not supplied)
Controls the opening of an external gas valve in concomitance with a switch-on
request of the burner in the boiler
In a plant divided in areas, relay 2 controls the secondary area
Relay 3 not used
Check the boiler circulation pump
The relay signals the intervention of a boiler block (can be combined with an
external indicator, not supplied)
The relay signals that the boiler is on
(can be combined with an external indicator, not supplied)
Controls the opening of an external gas valve in concomitance with a switch-on
request of the burner in the boiler
If the external probe reading is not correct it is possible to correct it in order to
compensate any environmental factors
