Optimizer (optimizing time constant)
Optimizes the start and stop times for the comfort temperature period to
obtain the best comfort at the lowest energy consumption.
The lower the outdoor temperature, the earlier the heating cut-in. The lower
the outdoor temperature, the later the heating cut-out.
The optimized heating cut-out time can be automatic or disabled. The
calculated start and stop times are based on the setting of the optimizing
time constant.
See Appendix "Parameter ID overview"
Adjust the optimizing time constant.
The value consists of a two digit number. The two digits have the
following meaning (digit 1 = Table I, digit 2 = Table II).
OFF:
No optimization. The heating starts and stops at the
times set in the schedule.
10 ... 59: See tables I and II.
MENU > Settings > Optimization
Based on (optimization based on room / outdoor temp.)
The optimized start and stop time can be based on either room or outdoor
temperature.
See Appendix "Parameter ID overview"
OUT: Optimization based on outdoor temperature. Use this
setting if the room temperature is not measured.
ROOM: Optimization based on room temperature, if measured.

Dimensioning temperature:
The lowest outdoor temperature (usually determined by your system
designer in connection with the design of the heating system) at which
the heating system can maintain the designed room temperature.
Example
The system type is radiator, and the heat accumulation of the building
is medium.
The left digit is 2.
The dimensioning temperature is -25 °C, and the capacity is normal.
The right digit is 5.
Result:
The setting is to be changed to 25.
