Adjusting the heating temperature

If the heating temperature must be increased or decreased,
turn the knob (5) until the desired value is reached. The temper-
ature can be set to between 45 and 85°C.

WARNING
To ensure constantly optimal performance of the gen-
erator, we suggest NOT to adjust the heating thermostat
to below the 60°C working temperature
60÷75°C

Adjusting the hot water temperature

If the domestic hot water (DHW) temperature must be in-
creased or decreased, turn the knob (4) until the desired value
is reached. The temperature can be set to between 30 and 60°C.

CAUTION
For the boiler to be able to produce domestic water,
the air contained in the calorifier coil must first be
purged upon the initial start-up.
To facilitate this operation, before starting up the appliance,
position the slot of the screw that releases the check valve (1)
horizontally. After purging all the air, put the screw back into its
original position.

WARNING
If the domestic hot water storage tank has not been
used for a period of four weeks, sanitise the calori-
fier and the domestic hot water expansion vessel. To
perform this operation, exclusively contact the Sime
Technical Support Service or professionally qualified
personnel.

1.6.1
The manual-reset safety thermostat intervenes by triggering
the immediate lock-out of the burner, when the temperature
exceeds 100°C. The intervention of the safety thermostat is not
signalled but can be detected by the boiler thermostat (T>100°
C). To reactivate the appliance, wait until the temperature in-
dicated by the thermostat falls to roughly 75° C then unscrew
.
the protective cap and press the underlying shaft. Wait for the
completion of the fuel pre-heating and start-up phases until the
flame appears.

If any ignition or operating anomalies occur, the boiler will run
a "LOCK-OUT" and the PSB button will light up red. To reset the
burner ignition conditions, press the burner unlock button (PSB)
until the flame appears. This operation can be repeated 2–3
times at the most and, should it fail, wait for qualified technical
personnel to intervene.

is advisable to interrupt the boiler's operation for roughly
one hour.
