Application of the HPM models
The use of the two HPM models depends on the number of heat pumps in the heating system
and the control mode, as shown in the following table.

6.3 Base
Layout of the base
The base of the HPM is a separate component. The base is divided into two areas by a partition
(
3
).
The left area contains extra-low voltage connections (
1
) e.g. for sensors and 0–10V signals; the
right area contains low voltage connections (
6
) (mains voltage 230 V) for valve actuators and
pumps (→
