Even during the combustion analysis phase, the function that
switches the boiler off when the water temperature reaches
the maximum limit (about 90°C) remains enabled.
When the checks are completed:
- position the mode selector depending on the operating mode
desired
- adjust the selectors according to the client's requirements.

The boiler is supplied for use with methane gas (G20) and are
already factory set as speci
¿
ed on the rating plate, so do not
require any calibration.

All checks must be carried out exclusively by the Technical
Assistance Centre.

Thermoregulation only works with external sensor connected, so
once installed, connect the outdoor probe - accessory on request -
to the appropriate connections provided on the terminal board of the
boiler. This enables the THERMOREGULATION function.

The compensation curve for heating maintains a theoretical
temperature of 20°C indoors, when the external temperature is
b20°C and -20°C. The choice of the curve depends on
the minimum external temperature envisaged (and therefore on the
geographical location), and on the delivery temperature envisaged
(and therefore on the type of system). It is carefully calculated by
the installer on the basis of the following formula:
KT = T.outlet envisaged - Tshift
20- min. design external T.
Tshift = 30°C standard system
25°C floor installations
If the calculation produces an intermediate value between two
curves, you are advised to choose the compensation curve nearest
the value obtained.
Example: if the value obtained from the calculation is 1.3, this is
between curve 1 and curve 1.5. Choose the nearest curve, i.e. 1.5.
Selection of the KT must be made by acting on the P3 trimmer on
the card (see multi-wire electrical diagram).
To access P3:
- remove the housing
- turn the instrument panel forward
- undo the fixing screws of the terminal board cover
- unhook the board cover.

Live electrical parts (230 Vac).
The settable KT values are as follows:
- standard system: 1.0-1.5-2.0-2.5-3.0
- floor installation: 0.2-0.4-0.6-0.8
and appear on the display for a duration of about three seconds
after the rotation of trimmer P3.

The heat request is made by the closure of the room thermostat
contact, while the opening of the contact produces a switch-off.
The delivery temperature is automatically calculated by the boiler,
although the user may interact with the boiler. Using the interface
to modify the HEATING, you will not have the HEATING SET-
POINT value available, but a value that you can set as preferred
between 15 and 25°C. The modification of this value will not directly
modify the delivery temperature, but will automatically affect the
calculation that determines the value of that temperature, altering
the reference temperature in the system (0 = 20°C).

With the contact closed, the heat request is made by the delivery
probe, on the basis of the external temperature, to obtain a nominal
ambient temperature on DAY level (20°C). The opening of the
contact does not produce a switch-off, but a reduction (parallel
translation) of the climatic curve on NIGHT level (16°C).
This will activate the night time function.
