3.3 APPLIANCE FUNCTIONING
PARAMETERS.
The following table gives boiler functioning
parameters with factory settings.
To modify the parameters reserved for the
technician, an access code must be inserted,
which is supplied on request.
To insert the code:
- press the MODE and STEP keys at the same
time for 2 seconds, CODE will appear on the
display;
- press STEP and “C” will appear on the display
and subsequently a random number on the last
two digits;
Possible settings for technician and user
