10.5.10 Operation - Daikin Altherma 3 GEO Series Installer's Reference Manual

10 Configuration
Auto restart
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.

Disable protections
INFORMATION
The software is equipped with an "installer-on-site" mode
([9.G]: Disable protections), that disables automatic
operation by the unit. At first installation, setting Disable
protections is by default set to Yes, meaning automatic
operation is disabled. All protective functions are then
disabled. To enable automatic operation and the protective
functions, set Disable protections to No.
36 hours after the first power-on, the unit will automatically
set Disable protections to No, ending "installer-on-site"
mode and enabling the protective functions. If – after first
installation – the installer returns to the site, the installer
has to set manually Disable protections to Yes.

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
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.

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

▪ error "U4" appears on the user interface,
▪ the heat pump module is connected to preferential kWh
