2.11 Electrical scheme
The electrical connection has to be reported with
your local electricity supply.
The required size of the upstream fuse for the main
electric circuit can be seen within the technical data
on page 3 and 4. It is important to use a sluggish fuse
(characteristic D). The relevant wire diameter has to
be calculated by an electrician.

integrated.

water pump
and adjusted.
The heat pump is usually operated with a weather
compensating flow temperature control.
The connections to control the heat pump with a
are prepared inside the console. (Look
up the electrical connections on page 12)
The

margins to insure a trouble free operation of the heat
pump (it can be asked at your local electricity supp-
lier)
