Basic principles of application 130 for ECL Comfort 110
Typically, the flow temperature is always adjusted according to your requirements.
The flow temperature sensor (S3) is the most important sensor. The desired flow
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 flow
temperature.
The motorized control valve (M1) is opened gradually when the flow temperature is
lower than the desired flow temperature and vice versa.
The return temperature (S4) to the district heating supply should not be too high. If so,
the desired flow 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 flow temperature can be adjusted.
The circulation pump, P1, is ON when the desired flow 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.
