Basic principles of application 130 for ECL Comfort 110
Typically, the ow temperature is always adjusted according to your requirements.
The ow temperature sensor (S3) is the most important sensor. The desired ow
temperature at S3 is calculated in the ECL Comfort controller, based on the outdoor
temperature (S1). The lower the outdoor temperature, the higher the desired ow
temperature.
The motorized control valve (M1) is opened gradually when the ow temperature is
lower than the desired ow temperature and vice versa.
The return temperature (S4) to the district heating supply should not be too high. If so,
the desired ow temperature can be adjusted (typically to a lower value) thus resulting
in a gradual closing of the motorized control valve. In boiler-based heating supply the
return temperature should not be too low (same adjustment procedure as above).
If the measured room temperature does not equal the desired room temperature, the
desired ow temperature can be adjusted.
The circulation pump, P1, is ON when the desired ow temperature is higher than 20 °C
(factory setting) or the outdoor temperature is lower than 2 °C (factory setting).
°C (degrees Celsius) is an absolute temperature whereas K (Kelvin) is a relative temperature.

Setting the desired room temperature
Change the desired temperature.
The setting of the desired room temperature is important even if a room temperature sensor
/ room panel / remote control is not connected.
Is the room temperature too low?
Make sure that the radiator thermostat(s) does not limit the room temperature.
If you still cannot obtain the desired room temperature by adjusting the radiator
thermostats, the ow temperature is too low. Increase the desired room temperature.

Heat curve
The ECL Comfort 110 controls the heating system according to the calculated ow
temperature under the inuence of the return and / or room temperature.
The desired ow temperature is dened by 5 settings: ‘Temp. max.’, ‘Temp. min.’, ‘Slope’,
‘Displace’, and ‘Knee point’.
