Room group 2:
Factory setting

[Curvepoint 2] flow temp min 20 °C
If the minimum flow temperature heating setpoints at both curve-
points are set to the same value (factory setting), the composite out-
side temperature has no impact on the minimum flow temperature
setpoint.
If the outside temperatures at both curvepoints are set to the same
value, the minimum flow temperature heating setpoint at this com-
posite outside temperature changes abruptly.
If the minimum flow temperature heating setpoints are set differently
and there is no valid outside temperature, the central apartment unit
displays an error message.
Maximum limitation
Maximum limitation limits the flow temperature heating setpoint at the top.
Even if more heat is called for, the temperature level is not exceeded.
Maximum limitation cannot be considered to be a safety function as
required with floor heating systems, for instance.
