4 2 2 Slope 0_2 to 3_5 1_5
If the external sensor is
used, the boiler calculates
the most suitable heating
ow temperature taking the
external temperature and
the type of appliance into
account.
The type of curve must be
chosen according to the type
of appliance radiator and the
heat losses present in the
building.

4 2 3 Parallel shift - 20 to + 20 0
To adapt the thermal curve to the appliance requirements, it is possible to perform a parallel shift of the curve in order to alter the
calculated ow temperature and therefore the ambient temperature.
The shift value between - 20 and + 20 is shown on the display. Each level corresponds to a
1°C increase in the ow temperature
in relation to the initial setting.
4 2 4 Compensation 0 to + 20 20
if setting = 0, the temperature taken from the ambient sensor does not aect the calculation
of the setting. If setting = 20, the temperature taken has maximum inuence on the setting.
