Regulation parameters
In case of POPGG regulation the only parameter to set is the hysteresis (dIF), which
can have values between 0.1°C e 1°C.
In case of proportional regulation the parameters to set are the regulation band (bnd) e
il periodo di regolazione (PEr).
For further information about how to choose these values see the chapter
“Regulation types” on page 25.
But remember that the preset settings are suitable for the most part of the
situations: to change these settings only if it’s really necessary.

It’s possible to choose a value between 1°C and
10°C. It’s also possible to deactivate the antifreeze
function pressing the key
