Auxiliary Function (Dhw) - Viessmann vitocal 300-g Operating Instructions Manual

Selecting DHW heating

Auxiliary function (DHW)

As additional protection against bacteria, you can select "Pasteurisation".
The total cylinder content will be heated
at the first cylinder heating every Monday
to the "Set temp. 2" (see next chap-
ter).
In order that bacteria are also killed in the
DHW circulation line, the DHW circula-
tion pump (if installed) is started in addi-
tion to the cylinder heating.
Note
Temperatures above 60 °C can only be
achieved with an instantaneous heating
water heater in the heating flow or an
electric immersion heater EHE in the
DHW cylinder.
