pump cascade are set during commis-
sioning by a certified heat pump contrac-
tor.
Instructing the system user
The system installer should hand the
operating instructions to the system user
and instruct the user in operating the
system.
This includes all components installed as
accessories, e.g. remote control units. In
addition, the system installer must make
the user aware of the required mainte-
nance work.
