ROOM TEMPERATURE REGULATION
We want here to remind you that the room tem-
perature must be regulated through a room ther-
mostat with two temperature levels. This required
by DPR 26 Agosto 1993 n°412 and relevant
changes.
SYSTEM FILLING
Make sure that the system pressure in a cold state is
always between 0.5÷1.5 bar (optimal pressure: 1÷1.5
bar). If pressure is lower, open the filling valve (see
figure) till it reaches a maximum value of 1,5 bar; this
value is checked with the pressure gauge (item 6 in
previous Control Panel figure).
Working and warning
indicators
GREEN FUNCTIONING LAMP [1]
The green lamp can be off, flashing (slowly or rapidly) or on.
OFF: the boiler is electrically disconnected. In these conditions the boiler obviously doesn’t
work. The Automatic Anti Freezing and Anti Blocking functions can’t be activated (useful during
long period of inactivity). The external general switch could be off.
FLASHING (slowly): the boiler is electrically supplied but the SUMMER/WINTER Selector is in
central position (0). The boiler will not turn on following the needs of heating and water in the
boiler won’t be maintained hot, but the Anti Freezing and Anti Blocking Functions are on (this
last can request the temporary ignition of the burner, then it is necessary that the gas is open).
FLASHING (rapidly): the Chimneysweeper Function (which is reserved for the technician) is on
by mistake.
Turn it off bringing the SUMMER/WINTER selector in the central position (0) until the green
lamp flashes slowly.
ON: the boiler is on and the SUMMER/WINTER selector is in the SUMMER
Position or in the
WINTER
Position. The boiler will turn on following the needs of heating or to keep the water
in the boiler hot.
