- After the “Start-up phase”, “WAIT COMM.” will always
appear, which means that the SC07 front control is waiting
for communication with the boiler. After which, the “Operation
phase” starts: in this phase it is possible to perform all the
supported actions (with the exception of language selection).
The controller stays in the “Operation mode” for 60 seconds
starting from the last time a knob was rotated or a key was
pressed. After 60 seconds has expired, the controller goes into
a “Stand-by” mode, back-light OFF. If there is a knob rotation or
a button pressed the device goes back to the “Operation mode”,
back-light ON, for a period of 60 seconds.
