Domestic hot water

Domestic hot water management is of priority compared to the system.
In DHW production mode, the compressors start only if the DHW storage
temperature is above a minimum threshold.
The maximum supply temperature threshold of the system is variable
based on the outdoor temperature.
To prevent it from falling below the minimum temperature, it is advisable
to install a backup electric heater on the DHW storage.
