Optimizing Time Constant; Adaptive Function Of Room Temperature - Danfoss ECL COMFORT User Manual

Service parameter(s) 14-15

14 Optimizing time constant

Circuit
(I) / (II)
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
Digit 2
OFF: No optimization. The heating starts and
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
(I) / (II)
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.
