j) Radiator offset (“OFFS”)
This setting option is only displayed if you use more than
one valve operating mechanism.
If several radiators are controlled by one heating control, it
may occur that these radiators are not heated up uniform-

The reason for this is that the flowrates of different valves
differ greatly, depending on different or bad radiator dimen-
sions. This problem may be solved by adjusting the settings
of single radiators in such a way that they give off more
(positive offset) or less (negative offset) heat.
