CH MIN allows adjustment of the minimum central heating flow temperature. This
value is used to calculate the curves used for the external probe. Values that are too
high can cause flow temperatures that are too high on average for room central
heating.
OFFSET (regulation constant), constant that can be regulated from -15ºC to +15ºC
and which in the presence of the optional external probe modifies the set flow
temperature set as standard at 0ºC.
NOTE; if the self-learning function is enabled the offset value could be modified
automatically.
BUILD (dimension and build inertia), adjustable from 1 to 20, default setting is 10.It
establishes the reaction speed of the system depending on the type of system
present. Example:
