10.7 Generation of setpoint
10.7.1 Weather-compensated control
Weather-compensated control is used with plant types 1−x, 2−x and 3−x. The setpoint is
generated via the heating curve as a function of the outside temperature. The tempera-
ture used is the
composite outside temperature.

10.7.2 Demand-compensated control
Demand-compensated control is used with plant types 4−x, 5−x, and 6−x.
The setpoint is delivered to the RVL481 via the data bus (LPB) in the form of a heat de-
mand signal. In that case, the outside temperature will not be taken into consideration.
