Ramp (reference ramping)
Setting range
OFF / 1 ... 99 min.
The time in which the desired flow temperature increases gradually to avoid load peaks in the heat
supply.
Set the ramping time for the controller.
Temp. °C
Setting line 5013
In order to avoid load peaks in the supply network, the flow temperature can be set
to increase gradually after a period with setback temperature. This causes the valve to
open gradually.
Optimizer (optimizing time constant)
Setting range
OFF / 10 ... 59
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:
Left digit Heat accumulation of the building
1X
2X medium
3X heavy
4X medium
5X heavy

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.
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.
It is only possible make use of 'Optimize' if the ECL Comfort 110 controller has a built-in ECA
110 timer program or is connected to an ECA 61 / 63.
Based on (optimization based on room / outdoor temp.)
Setting range
ROOM / OUT
The optimized start and stop time can be based on either room or outdoor temperature.
ROOM: Optimization based on room temperature, if measured.
OUT: Optimization based on outdoor temperature. Use this setting if the
room temperature is not measured.
