Comfort Function
The supply of water for domestic use can become more conven-
ient by means of the "COMFORT" function, which maintains the
secondary exchanger at a preset temperature when the boiler is
not running; thereby allowing a quicker delivery of domestic water
when required. This function is activated by pressing
the
button on the control panel. When the function is on, a
yellow L.E.D. "G" on the control panel will illuminate.
Note: If the "COMFORT" function is on during the pump overrun
period, it will be temporarily deactivated. The yellow L.E.D. "G"
will remain on to indicate that the boiler will resume the "COM-
FORT" mode once the pump overrun period is complete.
Periodic operation of the appliance will occur regardless of
demand on the boiler. This function is normal operation
