The documentation for the ECL Comfort controller is composed of numbered sections. [. . . ] 10: The setback temperature depends on the outdoor temperature, when the outdoor temperature is above the set limit. The lower the outdoor temperature, the less the temperature reduction. When the outdoor temperature is below the set limit, there is no temperature reduction. OFF: The setback temperature does not depend on the outdoor temperature.

Setting range
Set the percentage at which you want the desired flow temperature increased temporarily. In order to shorten the heating-up period after a setback temperature period, the desired flow temperature can be increased temporarily (max. At optimizing the boost is active in the optimization period (line 14). If a room temperature sensor or an ECA 60 / 61 / 62 / 63 is connected, the boost stops when the room temperature has been reached. The boost also stops at the end of an optimizing period.

I OFF / 10 . . . 59 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.

Temperature °C
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.

In order to avoid load peaks in the supply network, the flow temperature can be set to increase slowly after a period with setback temperature. This causes the valve to open slowly.
15 Adaptive function of room temperature Circuit Setting range Factory setting I OFF / 1 . . . 30 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. The desired temperature is adapted slowly.

OFF: The desired flow temperature in circuit I is not influenced by any other controller (slave or circuit II). 20: The desired flow temperature is increased by the set value (line 17), if the demand of a slave / circuit II is higher.

The desired flow temperature is lowered to 10 °C. setting of the flow temperature (line 2, section 22) is overruled.
Desired flow temp. [. . . ] The temperature is controlled according to your schedule with automatic changeover to / from comfort and setback temperature periods. In the DHW circuit, however, the DHW temperature is controlled according to the setback temperature.
The setting of the desired room temperature is important even if a room temperature sensor / room panel / remote control is not connected. Make sure that the radiator thermostat does not limit the room temperature. If you still cannot obtain the desired room temperature by adjusting the radiator thermostats, the flow temperature is too low. [. . . ]
