Permanent timing reduction. e boiler is fitted with an
electronic timer that prevents the burner igniting too frequently
in the central heating phase.
e boiler is supplied with a timer as a standard feature, set
at 180 seconds.

Central Heating ramp timing. e boiler supplies the maxi-
mum output set in the previous parameter.
e boiler executes an ignition ramp of about 650 seconds to
go from minimum to nominal central heating output.

Central heating ignitions delayed due to Room thermostat
or Remote control requests. e boiler is set to turn on im-
mediately after a request.
In the case of particular systems (i.e. zone systems with mo-
torised thermostat valves, etc.) it might be necessary to delay
ignition.

Domestic hot water thermostat. If the “correlated” thermostat
is set the boiler switches off according to the temperature set
with the d.h.w. adjustment knob.
While if the “fixed” d.h.w. thermostat is set, switching off
temperature is set at 85°C regardless of what position the
knob is in.

Circulator function. Two circulator functioning modes can
be selected in the central heating phase.
In the “intermittent” mode, it is activated either by the Remote
control or eventual by the room thermostat, in the “continua-
tive” mode the circulator works all the time when the main
selector switch by Remote control is on heating.
