Cable bushing for motorised valve drives
Different to conventional thermal valve drives,
the motorised valve drive can move to any valve
position calculated by the floor heating controller
to achieve the desired room temperature. This
provides a constant heat flow and continuous
heat emission. When switching from convention-
al to motorised valve actuators, it is possible in
rare cases that flow noises may occur at the heat-
ing circuit manifold when the pump pressure is
set high and the valve openings are small. You
can fix this by changing the pump settings or by
adjusting the parameters of the floor heating
controller.
