Brine
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 tolerances, the brine
concentration MUST resist to a lower temperature than the defined
setting.
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 –2°C, then the unit freeze up prevention limit
temperature MUST be set to –12°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.

NOTICE
The
Brine freezing temperature
setting can be
modified and read out in [9.M]. This setting can ONLY be
modified 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.
