Basic principles of application 116 for ECL Comfort 110

If the measured flow (DHW) temperature (S3) is lower than the desired DHW

temperature, the motorized control valve (M1) is opened gradually 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, i.e. the return temperature will

decrease.

The circulation pump, P1, is ON when the desired flow temperature is higher than 20 °C

(factory setting) or the actual flow temperature (S3) is below 10 °C (factory setting).

°C (degrees Celsius) is an absolute temperature whereas K (Kelvin) is a relative temperature.
