1. Description of the heating circuit station
The HSU and HSM heating circuit stations are pre-
assembled units. The electrical wiring is compliant with
VDE regulations. The entire flow and return pipeworks
are pre-assembled and sealed. Only flat-sealing screw
fittings are used.
The cables are connected to the heating circuit station
with screw fittings that need to be ordered separately.
The insulation shell is made from water vapour expan-
ded polypropylene (EPP). This material is environ-
