POST ADJUSTMENT AND VENTING
Pump adjustment, automatic operation
Brine side
To set the correct flow in the brine system, the brine
pump must run at the correct speed. F1345 has a brine
pump that is controlled automatically in standard mode.
Certain functions and accessories may demand that it
be run manually, in which case the correct speed must
be set.
TIP
For optimum operation when several heat
pumps are installed in a multi-installation, all
heat pumps should have the same compressor
size.
This automatic control occurs when the compressor is
running and sets the speed of the brine pump so that
the optimum temperature difference between the supply
and return lines is attained.
Heating medium side
To set the correct flow in the heating medium system,
the heating medium pump must run at the correct
speed. F1345 has a heating medium pump that can be
automatically controlled in standard mode. Certain
functions and accessories may require it to run manually
and the correct speed must then be set.
This automatic control occurs when the compressor is
running and sets the speed of the heating medium
pump, for the relevant operating mode, so the optimum
temperature difference between the supply and return
lines is achieved. During heating operation, the set DOT
(dimensioned outdoor temperature) and temperature
differential in menu 5.1.14 are used. If necessary, the
maximum speed of the circulation pump can be limited
in menu 5.1.11.
Pump adjustment, manual operation
Brine side
F1345 has brine pumps that can be controlled automat-
ically. For manual operation: deactivate "auto" in menu
5.1.9 and then set the speed according to the diagrams
below.
Caution
When an accessory for passive cooling is used,
the brine pump speed must be set in menu
5.1.9.
Set the pump speed when the system has come into
balance (ideally 5 minutes after compressor start).
Adjust the flow so the temperature difference between
brine out (BT11) and brine in (BT10) is between 2 - 5 °C.
Check these temperatures in menu 3.1 "service info"
and adjust the brine pumps’ (GP2) speed until the tem-
