Your thermostat can be programmed to have each day of the week
programmed uniquely (7 days), all the weekdays the same with a separate
program for Saturday and a separate program for Sunday (5+1+1), or
non-programmable. For the 7-day and 5+1+1 programming modes, there are
three time period options.

This thermostat has a programmable fan feature, which allows you to run the
fan continually during any time period.
