The preselected setpoints for Comfort and Precomfort mode can be readjusted by
±3 K on the QAW740 room unit.
It is possible to use a conventional room temperature setpoint adjuster (absolute or
relative). For more detailed information about this subject, refer to the following 2
sections.
The 4 setpoints are to be readjusted according to the following rules:
• Simultaneous readjustment of Comfort and Precomfort setpoints
• When the Economy setpoint is reached, it will be shifted together with the Precomfort
setpoint
• In Protection mode, the Comfort, Precomfort and Economy setpoints are limited
The effective setpoint appears on the Main menu and on the info page.

9.4.2 Raising the Economy setpoint
The room temperature setpoint in Economy mode is increased as a function of the
composite outside temperature. The increase is greater at low outside temperatures
and reduced to zero at high outside temperatures, whereby starting and end point are
adjustable.
The function helps prevent peak loads when changing from Economy to Precomfort or
Comfort mode.
