423Parallel shift from - 7 to + 7 (low temperature) 0
from - 14 to + 14
(high temperature)
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.
By accessing this parameter or pressing the buttons 12 the curve can be shifted in a parallel
manner as indicated in the gure shown below.
The value is indicated on the display:
- from -7 to +7
(low temperature)
- from -14 to +14
(high temperature)
Each step represents a ow temperature increase/decrease of 1°C in relation to the
set-point value.
424Compensation from 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.

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.
