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.
6 2 3 Parallel curve shift Zone 2 Offset 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.
6 2 4 Compensation from 0 to 20 20 if setting = 0, the temperature
taken from the ambient sensor
does not affect the calculation
of the setting. If setting = 20,
the temperature taken has
maximum inuence on the
setting.
