There are no settings required.
It is not recommended to use a QAA25 room temperature setpoint adjuster since its
characteristic is not linear so that setpoint deviations of maximum 1 K would occur.
Compensation is not possible.
The adjusted setpoint represents the Comfort setpoint. At the same time, the Precomfort
setpoint is displaced parallel, which means that the difference between the 2 setpoints will
be maintained.
