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.
