The h/H stay lit while they are above certain values of times,
depending on the power selected.
The time counter is found in the ELIN, which transfers the

maximum powers.
If, for example, we switch on any burner at maximum level, in
approximately 8 seconds, the small letter appears.

In the factory, some device operation tests are carried out and at
times they forget to return to the factory values.
Then, when the device is connected, the small “h” appears in the
touch Control without having switched on any zone. .
The small “h” remains static for 37 minutes until disappearing and
then the operation returns to normal.
It can also be deleted entering the technical service programme and
accessing step 2. See technical service programme and how to
access according to the corresponding model.
