Electrical installation

NOTE
Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician, and in accordance with applicable
electrical safety regulations.
SENSORS
VPB 200 and VPB 300 can be supplemented with up to
two hot water sensors, one for display and one for
control. The display sensor is positioned in the sub-
merged tube for the display sensor (UA1) and the control
sensor is positioned in the submerged tube for the
control sensor UA2. In cases where it is only possible
to connect one sensor, use the submerged tube for the
control sensor (UA2).
VPBS 300 can also be supplemented with a solar sensor.
This is placed in a submerged tube for the 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.
