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. GreenMaster-HP
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.
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.
GreenMaster-HP 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
GreenMaster-HP has a brine pump that can be automat-
ically controlled. For manual operation: deactivate "auto"
in menu 5.1.9 and then set the speed according to the
diagram below.
Caution
When an accessory for passive cooling is used,
the brine pump speed must be set in menu
5.1.9.
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 pump's (GP2) speed until the temperat-
ure difference is obtained. A large difference indicates
a low brine flow and a small difference indicates a high
brine flow.
Heating medium side
GreenMaster-HP has a heating medium pump that can
be automatically controlled. For manual operation: de-
activate "auto" in menu 5.1.11 and then set the speed
according to the diagrams below.
Readjusting, venting, heat medium side
Air is initially released from the hot water and venting
may be necessary. If gurgling sounds can be heard from
GreenMaster-HP or the climate system, the entire system
requires additional venting. Check the pressure in the
pressure expansion vessel (CM1) using the pressure
gauge (BP5). If the pressure drops, the system should be
topped up.
Readjusting, venting, collector side
Expansion vessel
Check the pressure in the pressure expan-
sion vessel (CM3) in GreenMaster-HP using
the pressure gauge (BP6). If the pressure
drops, the system should be topped up.
