10.4.2 Increasing the Economy setpoint
The room temperature setpoint of Economy mode is increased depending on the
composite outside temperature. The increase is greater at low outside temperatures
and zero at high outside temperatures; the transitions are adjustable.
The function helps prevent peak loads when changing from Economy to Precomfort or
Comfort mode.

10.4.3 Room temperature setpoint adjuster, absolute
For preselection of the room temperature setpoints for Comfort and Precomfort mode, a
remote setpoint adjuster (e.g. BSG21.1) can be configured.
The 4 setpoints can be readjusted as shown in the following illustration.
The upper curve shows the difference between the remote setpoint adjuster’s setpoint
and the selected Comfort setpoint. This difference affects the other setpoints in different
ways. This is shown by the curves in the lower part of the diagram.
