scription
Problem
Individual radiators do not warm up
properly.
In the spring and autumn, the
required room temperature is not
achieved.
The required room temperature
is not achieved when outside
temperatures are very low.
Remedy
Carry out hydraulic balancing,
i.e. reduce the flow rate of hotter
radiators.
Increase the pump speed (H16).
Increase the set room temperature
at the controller, e.g. with set value
setting ± 4.
Select a steeper heating curve at
the controller, e.g. increase the flow
temperature at standard outside
temperatures.
