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 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 8 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.
