Honeywell 301C User Manual page 56

The fourth screen in the Config menu allows a definition of a day and a
week to be programmed.
Day and Week definition allows hours (time frames) to be defined for
either Daytime and Working Days respectively.
Note: Remember, the controller uses a 24 hour clock (0:00 to 23:59).
Any time changes (e.g., for Daylight Savings Time) must be
made manually or through BACNet time synchronization
(BACNet module required).
