Auto restart
When power returns after a power supply failure, the auto restart function
reapplies the remote controller settings at the time of the power failure.
Therefore, it is recommended to always enable the function.
If the preferential kWh rate power supply is of the type that power supply is
interrupted, always enable the auto restart function. Continuous indoor unit
control can be guaranteed independent of the preferential kWh rate power supply
status, by connecting the indoor unit to a normal kWh rate power supply.

INFORMATION
Protective functions – "Installer-on-site mode". The software is equipped with
protective functions, such as room antifrost. The unit automatically runs these
functions when necessary.
During installation or service this behaviour is undesired. Therefore, the protective
functions can be disabled:
▪
At first power-on: The protective functions are disabled by default. After 36 h
they will be automatically enabled.
▪
Afterwards: An installer can manually disable the protective functions by setting
[9.G]: Disable protections=Yes. After his work is done, he can enable the
protective functions by setting [9.G]: Disable protections=No.

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.
