4. Accessories
A temperature NTC sensor with measurement
terminal (1021797) is ideal for measuring the
temperature at various places along the copper
piping, since it can be clamped directly to the cop-
per and provides good thermal conduction be-
tween the pipe and the sensor. It can be used in
conjunction with the "VinciLab" datalogger
(1021477).

6. Operation
6.1 Filling the water containers
Fill up the water containers with water and
move them with the low edge first under the
evaporator and the condenser.
Turn the beakers in such a way that the high
edge points to the back wall.

6.2 Configuration
Follow the safety instructions under point 2
Allow the heat pump to stand upright for at least
7 h before using it if it was tipped over.
To start the pump, fill the two water reservoirs
and connect the pump to the mains.
Turn on the compressor.
Note: the energy meter works even when the
compressor is switched off.
