No heat pump
There is no connection to the outdoor unit module. Check the power supply and
the interface cable to the outdoor unit module
Frozen boiler
When the power supply is turned on, the water in the water heater has a
negative temperature and may have frozen. Check the integrity of the water tank
and then turn it on again
Unprotected
solar
The solar installation is switched off from the menu "
Heat sources
" and if it
exists, it may be damaged by overheating or freezing
Heat sources
turned off
All heat sources in the menu "
Heat sources
" are turned off. If the solar
installation exists, it may be damaged by overheating or freezing. The same
applies to switching off the mode for protection of the water tank against freezing.
Overheating
solar
Overheating of the solar system is registered, if the temperature t3 exceeds the
temperature in the field "
Overheating solar
" in the menu "
Solar protection
"
Overheating
boiler
The temperature at the top of the water heater exceeded 84 ° C
Anti-
Legionella
The Legionella bacteria destruction mode was activated by heating the water by
the electric heater up to 70 ° C
Power supply
off
Last time and date when the thermoregulator was running before power supply
was interrupted
Power supply
on
Time and date, when the power supply was restored.
The above two messages will be registered if the system clock is set
Damaged
Flash
A malfunction of the microcontroller resulting in the failure to record the settings
in the non-volatile memory, i.e. changes to settings are lost when power supply is
lost.
