5 Electrical installation

NOTE
Electrical installation and service must be carried
out under the supervision of a qualified electri-
cian. 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.
This is placed in the submerged tube for solar sensor
(UA3).
Use the sensors provided with the heat pump/control
module. When no heat sensors have been provided these
must be ordered from the manufacturer of the heat
pump/control module.
