Domestic hot water
Option.
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 (see chart).
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
The following components are required:
 3-way valve SV1
 temperature probe Taf1
antifreeze protection for domestic hot water

temperature probe T5
regulation and switching between system and DHW production
Operations sequence:
1 disconnect the probe Taf1 supplied and connected as
standard on the unit (main board-CN69)
2 connect the probe Taf1 supplied as spare part with the 10mt
cable (main board-CN69)
3 after connecting the cable put the probe on the domestic hot
water line
4 connect T5 connector and put the T5 probe into the domestic
hot water storage
