Basic principles Control of district heating circuits with or
without heat exchanger and for boiler-based
heating circuits
Typically,theowtemperatureisadjusted
accordingtothedesiredowtemperature.
• Adjustmentofowtemperature
 Thedesiredowtemperatureiscalculated
in the ECL Comfort controller, based on the
outdoor temperature. The lower the outdoor
temperature,thehigherthedesiredow
temperature.
The motorized control valve is opened
graduallywhentheowtemperatureislower
thanthedesiredowtemperatureandvice
versa.
• Returntemperaturelimitation
The return temperature 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).
• Roomtemperaturelimitation
If the measured room temperature does not
equal the desired room temperature, the
desiredowtemperaturecanbeadjusted.
• Circulationpumpcontrol
The circulation pump is ON when the desired
owtemperatureishigherthanauser-dened
value (factory setting: 20 °C ) or the outdoor
temperature is lower than a user-defined
value (factory setting: 2 °C).
