Heating curve adaptation
(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 the room influence (see prog.no. 750, 1050, 1350) must be between
1% and 99%. Should there be radiator valves in the leading room (assembly loca-
tion 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.

24-hour heating limit
(732, 1032, 1332) The 24-hour heating limit shuts off the heating circuit if the current outside tem-
perature increases up to the difference set here of the current operating level (re-
duced or comfort set point). The heating cuts on again if the current outside tem-
perature again falls under the set difference minus 1°C.
This function is not activated in operation mode continuous operation comfort

Flow temp setpoint limita-
tions
min
(740, 1040, 1340)
max
(741, 1041, 1341) With this function, a range can be defined for the flow setpoint. When the re-
quired flow temperature setpoint of the heating circuit reaches the respective
limit value, this remains constantly on maximum or minimum value during con-
tinuously increasing or decreasing heat requirement.
If there is a direct circuit in parallel with other heating demands, it may result in
an elevated temperature in the direct circuit.
Flow temp setpoint room stat
(742, 1042, 1342) For room thermostat mode the flow setpoint set here applies.
In the setting
"--°C" , the value calculated via the heating curve is used as the set
flow temperature.
