Determination of the heating curve gradient
Enter the lowest calculated outside temperature in accordance with the
climate zone (e.g. -12 °C in Frankfurt) into the diagram (see fig.) (e.g.
vertical line at -12°C). Enter the maximum flow temperature of the heating
circuit, which is reached by calculating with -12 °C outside temperature at
20 °C room temperature (e.g. horizontal line at approx. 55 °C).
The intersection of both lines provides the value for the heating curve
gradient.
Heating curve displacement (721, 1021, 1321)
Heating curve correction by parallel offset if the room temperature is
generally too high or too low.
Heating curve adaption (726, 1026, 1326)
Automatic adaptation of the heating curve to the actual conditions, as a
result of which no correction of the heating curve slope is required.
Important
Automatic adaptation of the heating curve requires the connection
of a room sensor. 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 lead room (where the room sensor is
installed), these must be fully opened.

x Outside temp attenuated (prog.no. 8703)
The heating circuit switches to summer operation as soon as the average
outside temperature over the past 24 hours rises 1°C above the value set
here. 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
temperature increases up to the differential set here to the current
operating level (reduced or comfort setpoint). The heating switches on
again if the current outside temperature falls again below the set
differential minus 1 °C.
Important
In the operating mode continuous mode or this function is not
activated.
Flow temp setpoint min (740, 1040, 1340) and Flow temp
setpoint max (741, 1041, 1341)
With this function, a range can be defined for the flow setpoint. When the
flow temperature setpoint reaches the respective limit, this remains
constant, even if heat demand rises or falls.
If a pump heating circuit is operated parallel with other requirements, it can
cause higher resulting temperatures in the pump heating circuit.
Flow temp setpoint room stat (742, 1042, 1342)
For room thermostat mode the flow setpoint set here applies.
