The validity of the demand for heat will not be influenced. The compensating variable
will not be influenced either since load management is a short-term intervention.
23.5.3 Resetting the load control signals
The controller clears all load control commands 2 hours after their activation if they
have not already been reset via M-bus. In general, a load control command will not be
reset when a setpoint is reached; this means that the command is not only executed
once, but is valid during the entire duration of the intervention.
23.5.4 Use on the LPB
On operating line 154, it is possible to define whether the load control signals received
via M-bus shall be used only locally or, additionally, shall be passed on via LPB in the
segment or in the entire interconnected system.
The numbers on the display have the following meaning:
Input
Use
0
Only locally
1
In the same LPB segment
2
In the entire LPB system
• When the signals are delivered in the LPB segment, no other device in that segment
may be connected to the M-bus!
• When the signals are delivered throughout the LPB system, no other device in the
entire LPB system may be connected to the M-bus!
