(1)
Value in combined operation. 80 °C for boiler only operation (half of the total available power).
(2)
In transient operation, lower temperatures are allowed.
(3)
Only for EVO version.
(4)
Only for EVO version. 10 minute peak collection of domestic hot water. The exact value depends on the performance of the DHW buffer tank.
