10,07 Outside temperature compensation
When the (optional) external probe is installed, the boiler regulation system functions in "Outside temperature
compensation" mode. In this mode, the temperature of the heating system is regulated according to the external
climatic conditions, so as to guarantee a high degree of comfort and energy saving all year round. Specifically, when
the external temperature falls, the central heating outlet temperature is increased, according to a pre-determined
"compensation curve".
In this mode, the temperature set in parameter 1 of the operating menu becomes the maximum central heatin g
outlet temperature. This should be set to Maximum to allow the system to regulate over the entire working range.
The boiler must be set during installation by qualified personnel. Other minor modifications can be made by the user
