If the external sensor is used, the boiler calculates the most suitable heating fl 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.

Parallel curve shift Zone 2 Off set

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 fl 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 fi 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 fl ow temperature increase/decrease of 1°C in relation to the
set-point value.
