Outlet temperature 40 °C:
– At an inlet temperature ≤ 35 °C,
the heat generator starts in order
to reach the set outlet temperat-
ure.
– At an inlet temperature > 35 °C,
the heat generator stops or does
not start. If the inlet temperature
is < 30 °C, the heat generator
starts again.
Outlet temperature 60 °C:
– At an inlet temperature ≤ 55 °C,
the heat generator starts in order
to reach the set outlet temperat-
ure.
– At an inlet temperature > 55 °C,
the heat generator stops or does
not start. If the inlet temperature
is < 50 °C, the heat generator
starts again.
Only for products with integrated
