BOILER OPERATING INSTRUCTIONS
Make sure that the authorised technician who tested the boiler has stamped the guarantee booklet.
During the installation, the technician must carry out the following checks:
■The data on the data plate must correspond to that of the mains supply networks (gas, electricity, water);
■The boiler must be regulated according to its designed use and performance;
■The flue gas exhaust and combustion air intake system must be correctly installed and operational;
■The exhaust gas discharge and ventilation systems must comply with the requirements of national and local
standards regardless of whether the boiler is installed indoors, outdoors or in its own cabinet (see section
“Reference standards”.
General warnings
If there is any doubt as to whether the appliance has been tested by an authorised technician, do not attempt
to start it. All maintenance and gas conversion operations must be carried out by professionally qualified
personnel, registered in accordance with current legislation and according to UNI-CIG 7129/01 and
subsequent updates.
Make sure that the requirements relating to the air intake and ventilation of the room in which the
boiler is to be installed have been complied with.
The boilers can be installed outdoors in a partially protected location, in accordance with current
standards and where the minimum external temperature does not fall below –10°C. The manufacturer
will not be held responsible for installation in locations where the temperature falls to below –10°C.
The boiler is fitted with an antifreeze system. If the boiler is installed in a location where there is a risk of
freezing, the anti-freeze system will only come into operation if there is power supply to the boiler and the gas
supply valve is open. The manufacturer will not be held responsible for damage to the boiler caused by non-
compliance with this instruction.
Should any part of the boiler freeze-up, do not attempt to light it under any circumstances, but instead call the
Service Centre immediately.
The appliance’s combustion system must be checked every two years. This check includes testing the
efficiency of the boiler and must be carried out by authorised personnel possessing the qualifications as
required by current law.
Do not obstruct the ventilation openings in rooms where there are gas-burning appliances installed (boiler,
cooker, etc.)
The installation, first start-up, regulation and maintenance operations must be carried out exclusively by qualified
personnel (e.g. THERMOSTAHL authorised Service Centres). Incorrect installation can cause damage to
property and injury to persons or animals, for which the manufacturer will not be held responsible.

Starting - up the boiler
Open the gas Isolation valve located under the
boiler.
•
Press
the button 6 ‘ ’ (fig. 1); The boiler
will light automatically (with the WINTER mode
selected and room thermostat connected).
•Check that there are no flashing numbers on
the display 1(see error codes). If code H2O
appears on the display 1this denotes that
there is no water in the boiler. Consequently,
fill the system as described in section “Filling
the system”.
■“SUMMER” mode
To switch boiler operation to “SUMMER” mode, press button 6(see fig. 1). The boiler will only work for the D.H.W
system. The “SUMMER” mode setting of the boiler is signalled by the symbol lit continuously on the control
panel.
The automatic ignition system will light the burner every time there is a demand for domestic hot water. In this case,
the symbol on the control panel will flash.
■“WINTER” mode
To switch boiler operation to “WINTER” mode, press button 6(see fig. 1). The boiler will only work for the central
heating system. The “WINTER” mode setting of the boiler is signalled by the symbol lit continuously on the
control panel.
The automatic ignition system will light the burner every time there is a demand for room heating. In this case, the
symbol on the control panel will flash.
■“SUMMER-WINTER” mode
To switch boiler operation to “SUMMER/WINTER” mode, press button 6(see fig. 1). The boiler will work for both
central heating/D.H.W systems. The “SUMMER/WINTER” mode setting of the boiler is signalled by the symbols
lit continuously on the control panel.
The automatic ignition system will light the burner every time there is a demand for room heating or domestic hot
water, the functioning is signalled by the symbols flashing continuously on the control panel.
■Regulating the heating temperature
The heating temperature is regulated by knob 2 (see fig.1).
•Rotating the knob anticlockwise reduces the temperature.
•Rotating the knob clockwise increases the temperature.
•The range of temperature settings for the central heating runs from a minimum of 30°C to a maximum of 80°C,
or, in the case of low temperature operation, from a minimum of 25°C to a maximum of 59°C.
■
D.H.W. temperature control
The domestic hot water temperature is regulated by knob 3 (see “Control panel”).
•Rotating the knob anticlockwise reduces the temperature.
•Rotating the knob clockwise increases the temperature.
•
The range of temperature settings for the domestic hot water runs from a minimum of 35°C to a maximum of
60°C.

■Topping-up the system with water
The water pressure in the central heating circuit
must be checked during the entire period of
operation of the boiler. In this respect, the reading
on the pressure gauge M(fig. 2), located on the
lower part of the boiler, must not be less than 1
bar.
If there is insufficient water in the boiler, the code
H2O will flash on the display (see fig 2).
To bring the system back up to pressure, open
the external filling tap R (fig. 2) and use the
pressure gauge M(fig. 2) to check that the
system pressure reaches 1 bar and that the code
H2O lights up.
When the operation is complete, close the fill tap.
Diagnostics – Error codes:
This paragraph contains a list of error codes that the boiler may generate on the display 1 (see “Control panel”)
together with the relative indications and the operations that the user can carry out to reset the boiler.
If the problem re-occurs after the following actions have been taken, call an authorised Service
