Ground water system

GENERAL

With AXC 40 a ground water pump can be connected to the
heat pump if the software controlled output (AUX output)
is used for something else.

This connection enables the use of ground water as heat
source. The ground water is pumped up to an intermediate
heat exchanger. An intermediate heat exchanger is used to
protect the heat pump's exchanger from dirt and freezing.
The water is released into a buried filtration unit or a drilled
well.

The ground water pump runs at the same time as the brine
pump.

From software version 8233R2, the groundwater pump can
be controlled with an analogue control signal from 0-10 V.

Install the temperature sensors using cable ties, together
with the heat conducting paste and aluminium tape. Then
insulate with the enclosed insulation tape.

NOTE

To prevent interference, sensor cables to external
connections must not be laid close to high voltage
cables.
