5 Electrical installation

NOTE
Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician. Electrical installation and wiring
must be carried out in accordance with the
stipulations in force.

Sensors

VPB/VPBS can be supplemented with up to two hot
water sensors, one for display and one for control. The
display sensor is positioned in the submerged tube for
the display sensor (UA1) and the control sensor in the
submerged tube for control sensor (UA2). In cases
where it is only possible to connect one sensor, use the
submerged tube for control sensor (UA2).
VPBS 300 can also be supplemented with a solar sensor.
Sv PBD
This is placed in the submerged tube for solar sensor
(UA3).
Use the sensors provided with the heat pump (or other
heat source). When no heat sensors have been
provided these must be ordered from the manufacturer
of the heat source.
The figure shows VPBS 300.

Direct-current anode

VPB/VPBS Enamel is equipped with direct-current an-
ode and supplied with potensiostat from the factory.
UA3
The anode cable (W1) is installed in the anode from
the factory and only needs to be connected to the po-
tentiostat.
1. Route the anode cable (W1) along the docking
pipe, flow line (XL8).
2. Connect the anode cable (W1) to the potentiostat.
3. Connect the potensiostat to a suitable 230 V wall
socket.
NOTE
The cable between the potentiostat and the
anode must either be extended or shortened.
