Problem
Possible cause
Solution
Supply temperature too low
Wrong setting of automatic controls.
Adjust automatic controls, see instruc-
tions for automatic controls.
Defective controller. The controller does
not react as it is should in accordance
with the instructions.
Call in automatic controls manufacturer
or replace controller.
Outdoor sensor mounted or placed
incorrectly.
Mount/place outdoor sensor correctly.
Poor cooling
Strainer clogged.
Clean strainer.
Too small heating surface/ too small
radiators compared to the total heating
requirement of the building.
Increase total heating surface.
Poor utilization of existing heating
surface.
Make sure that the heat is distributed
evenly across the full heating surface -
open all radiators and keep the radiator
in the system from heating up at the
bottom. Higher temperature at the top
and lower temperature at the bottom
part of the radiators means that the
system operation is correct.
The system is single-pipe.
It is extremely important to keep the
supply temperature to the radiators as
low as ever possible, while maintaining a
reasonable level of comfort.
