This way, long heating up times when changing from Economy to Precomfort
or Comfort setpoint can be prevented at low outside temperatures.
In the case of night setback to Economy setpoint, this function leads to outside
temperature-compensated night setback.
If the settings for start and end point coincide, the function is deactivated.
An Economy setpoint raised through Economy increase is displayed on the
central apartment unit.
If there is no valid outside temperature when the ”Economy increase”
function is active, the central apartment unit displays an error mes-
sage.

Proportion of room unit
If QAW910 room unit and 1 or 2 QAA910 room temperature sensors are con-
nected to the same room, the room unit’s weighting (0..100%) with regard to
room temperature averaging can be set.
If 1 room unit and
1 room temperature sensor are used, the actual value of the
average room temperature is determined based on the percentage proportion
set.
If 1 room unit and
2 room temperature sensors are used, the average value of
the 2 room temperature sensors is determined first. The actual value of the
average room temperature is calculated based on the percentage proportion
set for the room unit and the room temperature sensor.
When
2 room temperature sensors are used, the average value of the 2 sen-
sors is delivered. The proportion of the individual sensors cannot be changed.
