What programming schedule options are available for the RT520TX thermostat?

The thermostat offers three program types: All (one schedule for the entire week), +2 (separate schedules for working days and the weekend), and Individual (a daily schedule). The schedule supports up to 6 time intervals per day, allowing between 2 and 6 different temperatures to be set. All time periods must be defined, and unused intervals can be removed by pressing the UP arrow on the interval until lines appear, then pressing SELECT to confirm removal.
