External heating program changeover (telephone contact)
An auxiliary device (e.g. VitocomĂ300) must be connected for this function.
The heating program, which was
manually preselected on the boiler
control unit, can only be changed
from a central control station or via
telephone and code transmitter.
The changeover occurs between the
heating programs allocated in the
table.
However, the heating program
selector position remains
unchanged.
A further call-up reloads the
preselected heating program.
With standard programming unit
Change coding addressĂ"35:00" to
"35:01".
