14 Optimizing time constant
Circuit Setting range Factory setting
(I) / (II) OFF / 10 ... 59 (OFF) / (OFF)
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.
Adjust the optimizing time constant. The value
consists of a two digit number.
The two digits have the following meaning:
Digit 1 Heat accumulation of

OFF: No optimization. The heating starts and
stops at the times set in the schedule.
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.
15 Adaptive function of room temperature
Circuit Setting range Factory setting
(I) / (II) OFF / 1 ... 30 (OFF) / (OFF)
Controls how fast the room temperature adapts to the desired
room temperature.
The adaptive funtion will eliminate the difference
between the desired and the actual room
temperature. This is done by integrating the
difference and adjusting the desired flow
temperature.
OFF: The adaptive funtion is cancelled.
1: The desired temperature is adapted quickly.
30: The desired temperature is adapted slowly.
