Electrical installation
NOTE
Electrical installation and service
must be carried out under the supervision of
a qualified electrician, and in accordance with
applicable electrical safety regulations.
SENSORS
The RSV boilers can be equipped with two hot water sensors:
sensor BT7 for displaying the hot water temperature on the heat
pump display and sensor BT6 for control. Sensor BT7 is fitted in
the submerged tube at the top side of the boiler (UA1), sensor
BT6 is fitted in the submerged tube in the center of the boiler
(UA2). The RSH boiler can only be equipped with a hot water
sensor for control (BT6). This sensor is fitted in the submerged
tube at the end side of the boiler (UA2).
All sensors must be properly fixed and make good contact with
the submerged tube(s). It is therefore recommended to use
contact paste. Only use the sensors supplied with the heat pump
(or another heat source). If sensors are not supplied, they must
be ordered from the manufacturer of the heat source. The internal
diameter of the submerged tubes is 8 mm.
