How to change the set-points
N.B.
When you change the appliance's operating parameters,
make sure you do not create situations of conflict
N.B.
The set-points can be viewed in full ONLY when the unit
is in stand-by. You are advised to put the unit in stand-by when
you change the set-points. If the unit is not in stand-by, the only
editable parameters are the ones relating to the unit's
operating mode. For example, in winter mode it is only possible
to change the winter set-points and the domestic hot water set-
point; in summer mode it is only possible to change the
summer set-points and the domestic hot water set-point.
