Pipe connections

General
When F1145/F1245/F1345 is docked to pool, the heating
circuits must be supplied with an external circulation
pump. This is because, during pool charging, the internal
circulation pump of the heat pump maintains a flow
through the pool heat exchanger. The extra/external cir-
culation pump (GP10) keeps the flow up in the heating
circuit, so the flow temperature sensor (BT25) can meas-
ure the temperature correctly.
Shuttle valve
Install the reversing valve (QN19) with port AB as incom-
ing flow line from the heat pump, port A towards the
pool and port B towards the heating system. Install it
so that port AB is open towards port B when the motor
is in standby mode. In the event of a signal port AB
opens towards port A.

Temperature sensor

The pool sensor (BT51) is located on the return line
from the pool.
The external flow temperature sensor (BT25) is located
on the flow line to the climate system, after the circu-
lation pump (GP10).
Install the temperature sensors with cable ties with the
heat conducting paste and aluminium tape. Then insulate
with supplied insulation tape.
NOTE
Sensor and communication cables must not be
placed near power cables.

Function
Heating of the pool is prioritised according to selected
settings in the heat pump.
If the pool sensor (BT51) is not connected, pool charging
is not permitted to start.
The heat medium flow is adjusted so that the temperature
difference over the pool accumulator is 10 - 15°C. The
setting is made in menu 5.1.11.
