NOTE
The control panel for the heating and heat
pump controller can be connected to a com-
puter or network using a suitable network ca-
ble, enabling the heating and heat pump con-
troller to be controlled remotely from there.
If such a connection is desired, route a
shielded network cable (
Ⓝ
, category 6, with
RJ45 connector) through the electrical switch
box and plug it to the corresponding socket
of the control panel.

NOTE
In devices with integrated electric heat-
ing element, the electric heating element
is connected for 9 kW (6 kW) in the factory.
At contactor Q, it is possible to select 6 kW
(4 kW) = 2 phase operation. Disconnect
Q5/6 for this. Or 3 kW (2 kW) = 1 phase op -
eration. Disconnect Q5/6 and Q5/4 for this.
The values in brackets are for the 6 kW heat-
ing element. Disconnected cables must be
furnished with screw terminals. Only the
phases cited above may be disconnected
(safety temperature limiter).
