Advanced Features - Honeywell Home THR860S User Manual

Advanced features

• Preset programme schedules: The programmer is preset to follow the schedules shown on page 10
(Schedule A) unless you change the settings. However, instead of changing the settings manually,
you can choose either of 2 other pre-configured schedules. Schedule B keeps heating and hot water
on longer if you're often at home. Schedule C keeps heating and hot water off longer to reduce
energy costs.
• Adjustable time settings: By default, the programmer has 6 time settings per day (3 on, 3 off). You
can reduce this to 4 time settings if desired (see page 23).
• Seasonal time change: The clock automatically changes in spring and autumn to correspond with
changes to and from daylight savings time (see page 22 to turn off this feature).
• Adjustable clock format: The screen can display time in either AM/PM format (i.e., 2 pm) or 24-hour
format (14:00) (see page 22).
• Adjustable backlight: A bright continuous backlight makes the display screen easier to read. You
can change its operation so the backlight always remains off or is lit for only a few seconds after
each button press (see page 22).
• Mini-Programmer option: This special operating mode is designed to compensate for the
inefficiency of some poorly controlled gravity hot water systems, which heat water whenever the
home heating system is on. The Mini-Programmer option blocks some operating modes (i.e., "Auto"
is not available in Heating, and "Off" is not available in Hot Water). (see page 23).
