Adjusting the heating temperature

If the heating temperature must be increased or decreased,
turn the knob (4) until the desired value is reached. The temper-
ature can be set to between 45°C and 85°C.
a
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

Possible faults

1.5.1

Safety thermostat

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.
a
WARNING
If the reactivation fails, DO NOT REPEAT it and wait for
qualified technical personnel to intervene.
1.5.2
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.

1.5.3
Sime ESTELLE HE ErP boilers are NOT equipped with a system
filling device. The system must be fitted with a pressure gauge
(A), to check that the (cold) water pressure is between 1 and 1.2
bar (98–117.6 kPa)
When the system water pressure indicated on the pressure
gauge (A) falls below 1 bar (98 kPa) , the unit must be filled.
To do this:
– open the filling valve (B) to raise the pressure until it reaches
the correct value, between 1 and 1.2 bar (98–117.6 kPa)
– close the valve (B)
NOTE:
above, open the relief valve of any radiator (some water will
come out) until the correct value is reached.

WARNING
Check that there is enough fuel in the tank and that the
shut-off valves are open. Once the tank has been filled, it
is advisable to interrupt the boiler's operation for roughly
one hour.
