U.motion KNX Server Plus, Touch
Installation Manual
The load control logic uses a two-level limit in order to prevent hysteresis phenomena (continuous switching
of loads); with one-level limits, the total load would fall back under the limit immediately after switching off a
single load, what would just cause the logic to turn the load back on again.

The section “LOADS” within the properties window of the load control it is possible to connect one or more ENERGY
COUNTERS, which act as loads (consumers) and must be configured for all the devices that should be actively controlled
by the load control logic, as described before.
Even in this case:
•
Either a previously configured ENERGY COUNTER can be connected
•
Or a new ENERGY COUNTER can be created using the ADD button
In the same way as for the „ENERGY COUNTER“ section, also here an automatic check is done, in order to control if all
loads present the necessary settings. If this is not the case (e.g. when adding a new counter using the ADD button), the
properties window of the related counter must be opened and the missing parameters must be set.
The required parameters are exactly the same as seen in the last chapter. The only difference lies in the following 2 sub-
objects, which are required for the single loads:
LOAD ON/OFF
Control object used by the load control logic in order to turn the load on or off.
This can be either a KNX object of 1bit or 2bit; in the first case, the corresponding output is just
turned on or off by U.motion KNX Server Plus Touch (with the risk that the state of the output might
be changed by another sensor or another event of the software); in the second case a force
(=priority) control of the output is executed, which brings the following 2 advantages:
•
The state of the load can’t be changed by other events (e.g. push buttons in the installation
or the VISUALISATION of U.motion KNX Server Plus Touch)
