enough, including the room in which
the boiler is installed; if this cannot be
done, both the boiler and the heating
system must be completely emptied.
Completely emptying the system also
means emptying the hot water tank
and the hot water heating coil.
3.5 ANTI THERMAL
INERTIA THERMOSTAT
The purpose of the anti thermal inertia
thermostat (TI) is to restart the boiling
unit pump when the boiler reaches the
temperature of 90°C, discharging the

When faults occur and/or the equip-
ment does not operate correctly, turn
it off, without attempting to make any
repairs or take direct action. For any

technical personnel in your area.
WARNING: If the LED signal is
missing or the colour changes
(blinking red/green or blinking
red), contact an authorised tech-
nician.
