At the read in of a new absolute comfort setpoint, the controller becomes a new basis comfort
setpoint. The new basic comfort setpoint causes also an adaption of the indirect setpoints at the
other operating modes. Through this function it is for example possible to read the actual room
temperature as new basic comfort setpoint i

setpoint. Sending a negative Kelvin value at this object causes a decrement of the current setpoint.

is for example set to a basic comfort setpoint of 3K, the setpoint can only be moved manual in the
limits of 18°C and 24°C.

whether the setpoint offset is only valid for the comfort mode or also for the night and standby
