Heating curve displacement
(721, 1021,1321)
Correction of the heating curve by parallel shifting in case of generally too high or
too low room temperature.
Heating curve adaption
(726, 1026, 1326)
Automatic adaptation of the heating nominal line to the actual circumstances,
due to which a correction of the heating nominal line gradient becomes obsolete.
For automatic adaptation of the heating curve a room sensor must be connected.
The value for room influence (see prog. no. 750, 1050, 1350) must be set between
1% and 99%. Should there be radiator valves in the leading room (assembly locati-
on of the room sensor), these have to be fully opened.
Summer/winter heating limit
(730, 1030, 1330)
As soon as the average of the outside temperatures of the last 24 hours rises 1°C
over the value set here, the heating circuit switches into summer mode. As soon
as the average of the outside temperatures of the last 24 hours drops 1°C below
the value set here, the heating circuit switches back into winter mode.
