Basic principles

Control of district heating circuits with or 

without heat exchanger and for boiler-based 

heating circuits 

Typically, the flow temperature is adjusted 

according to the desired flow temperature.

•   Adjustment of flow temperature
  The desired flow temperature is calculated 

in the ECL Comfort controller, based on the 

outdoor temperature. The lower the outdoor 

temperature, the higher the desired flow 

temperature. 

The motorized control valve is opened 

gradually when the flow temperature is lower 

than the desired flow temperature and vice 

versa.

•   Return temperature limitation
  The return temperature 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).

•  Room temperature limitation
  If the measured room temperature does not 

equal the desired room temperature, the 

desired flow temperature can be adjusted.

•   Circulation pump control
  The circulation pump is ON when the desired 

flow temperature is higher than a user-defined 

value (factory setting: 20 °C ) or the outdoor 

temperature is lower than a user-defined 

value (factory setting: 2 °C).
