▪ 1 (Sample)(default): The pump is ON
when there is heating demand and the
leaving water temperature has NOT
reached the desired temperature yet.
When thermo OFF condition occurs,
the pump runs every 5 minutes to
check the water temperature and
demand

Brine freezing temperature
Depending on the type and concentration of the anti-freeze in the
brine system, the freezing temperature will differ. The following
parameters set the units freeze up prevention limit temperature. To
allow for temperature measurement
concentration MUST resist to a lower temperature than the defined
setting.

tolerances, the
General rule: the units freeze up prevention limit temperature MUST
be 10°C lower than the minimum possible brine inlet temperature for
the unit.
Example: When the minimum possible brine inlet temperature in a
certain application is 0°C, then the unit freeze up prevention limit
temperature MUST be set to –10°C or lower. Result will be that the
brine mixture may NOT freeze above that temperature. To prevent
freezing of the unit, check the type and concentration of the brine
carefully.

[A.6.9] [A‑04]
NOTICE
The setting brine freezing temperature can be modified
and the read out is correct in [A.6.9] Brine freezeup temp
ONLY after having accessed menu [A.8] Overview
settings.
This setting can ONLY be modified and/or saved and the
read out is ONLY correct if the communication between
hydro module and compressor module is present. The
communication between hydro module and compressor
module is NOT guaranteed and/or applicable if:
▪ error "U4" appears on the user interface,
▪ the heat pump module is connected to preferential kWh
rate power supply where power supply is interrupted
and preferential kWh rate power supply is activated.
Capacity boost
For systems where higher capacity is required, the compressor
frequency can be increased. Remark that higher capacity results in
higher sound level.
