The system also envisages the option of setting time bands during which the heating unit is set to operate, if there is a
demand for heat, and those during which it remains off, or in ECO mode when fitted with an outside sensor.
There is a maximum of 6 programmable time bands within 24 hours, each of which must be identified by a start time (ON),
and end time (OFF). The minimum interval between each time is half an hour.
