Example: having set, in step "15", a CO

reading should be 9.0% (=9.5%-0.5%).
If the difference satisfies the delta CO

ced operation and return to the initial operational configuration.
After 30 minutes of operation the appliance automatically cancels the preceding for-
ced power mode. To anticipate this timing, select and execute action "25" in menu 2.
Switch off and completely restore the appliance.
