4.1.5 Max. Control value
The following illustration shows the settings for this parameter:

which you can see at the chart below. The maximum control value is only sent at a change or at a
change and additional cyclically every 30min.
This function allows

, which can modulate their power, if only less power is required. The
object for the output (Number 84/164) sends the maximum used value at the heating actuator of the
enabled channels. Afterwards this output signal can be analyzed and send the used power to the
heating.
If more than one heating actuator is used, which get all their heating power from one heating, the
objects can be connected by the additional object of the input (Number 85/165). Therefore, the
output of the first actuator has to be connected to the input of the second actuator and so on. Now
the output object of the last actuator sends the maximum used power from all enabled channels of
the connected actuators.
