During black-outs, the programmed parameters will not be lost as the settings are
stored in a non-volatile memory.
The internal battery of CH143A allows it to maintain the date/time during blackouts.
N.B. the chronothermostat works properly even when the battery is discharged, but
during blackouts it is not assured that the date/time will be maintained.
