6.4 Settings menu
You can set additional settings using the main menu screen and its
submenus. The most important settings are presented here.
6.4.1 Main zone
Thermostat type
Only applicable in external room thermostat control.
NOTICE
If an external room thermostat is used, the external room
thermostat will control the room frost protection. However,
the room frost protection is only possible if [C.2]
Space
heating/cooling = On .
# Code Description
[2.A] [C–05] External room thermostat type for the
main zone:
▪ 1: 1 contact : The used external room
thermostat can only send a thermo
ON/OFF condition. There is no
separation between heating or cooling
demand.
▪ 2: 2 contacts : The used external
room thermostat can send a separate
heating/cooling
thermo ON/OFF
condition.
6.4.2 Additional zone
Thermostat type
Only applicable in external room thermostat control. For more info
about the functionality, see

6.4.4 Brine freezing temperature
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.
# Code Description
[9.M] [A‑04] Brine freezing temperature :
▪ 0: 2°C
▪ 1: –2°C
▪ 2: –4°C
▪ 3: –6°C
▪ 4: –9°C
▪ 5: –12°C
▪ 6: –15°C
▪ 7: –18°C
NOTICE
The
Brine freezing temperature
setting can be
modified and read out in [9.M].
After changing the setting in [9.M] or in the field settings
overview [9.I], wait 10 seconds before restarting the unit
via the user interface to ensure that the setting is saved in
the memory correctly.
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.
