Options
P67.1
In winter mode the boiler pump and that of the main zone are always
(CONTI-
powered and therefore always function
NUE)
P67.2 In winter mode the pumps are managed by the room thermostat or by the
remote control
P67.3
In winter mode the pumps are managed by the room thermostat or by the
(ECO-
remote control and by the boiler flow probe

The boiler is set to ignite the burner immediately after a request for central
0s ÷ 500s heating. In the case of particular systems (e.g. zone systems with motorised
valves etc.) it could be necessary to delay switch-on
The boiler has an electronic timing device that prevents the burner from
0s ÷ 255s
igniting too often in the central heating phase.
The boiler performs an ignition ramp to arrive from minimum power to
0s ÷ 840s
nominal heat output.
Boiler ignition for heating the domestic hot water occurs when the water

contained in the storage tank falls by 3°C with respect to the temperature

(OFF2) set
(-10 °C) Solar function active, if the input domestic hot water has a sufficient tem-
perature the boiler does not switch on

(Can be coupled with an external indicator, not supplied)
Controls the opening of an external gas valve in concomitance with an ignition
