Economy increase

The Economy room setpoint for heating all rooms is raised depending on the

composite outside temperature. The increase at low outside temperatures

(e.g. end point -15 °C) is greater and negated at higher outside temperatures

(e.g. starting point -5 °C).

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 setting is made such that 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.

Room temperature rise

During optimum start control, the central apartment unit ascertains the room

temperature rise (min/K) of the respective room and takes it into account the

next time optimum start control is performed. The value calculated last can be

viewed via an operating line and can be changed, if required:

Proportion room unit

If a QAW910 room unit and 1 or 2 QAA910 room temperature sensors are

connected 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.
