About your new 2 channel programmer

The THR860SWE is designed to work with your existing thermostat, heating and hot water. It can work automatically, or you can adjust it manually to maintain a comfortable indoor environment while minimising energy use and costs associated with heating both your home and the hot water you require.

Features

• Energy-saving design: Automatically activates or shuts down your heating and hot water up to six times per day to ﬁt your lifestyle while saving energy costs. Each day of the week can be programmed separately (see pages 812).

• One-touch comfort control: Allows you to override programmed settings at any time by turning your heating or hot water on or off — or by extending an “on” period by up to three hours.

• Holiday button: Turns off your heating and hot water for up to 99 days while you are away, then resumes normal operation when you return (see page 12).

• Seasonal clock change: Automatically adjusts the clock for seasonal changes in the spring and autumn to adjust for standard time or daylight savings time.

• Lifetime memory: Saves your customised settings indeﬁnitely, even if the mains power supply fails.

Press the MODE button repeatedly to select an operating mode. You can set the Hot Water and Heating modes separately, by pressing the appropriate button as shown at left. Both work the same way:

Cont: Heating or Hot Water remains on continuously.

Auto: In this mode the programmer follows a daily schedule for

the Hot Water or Heating, turning each on and off at preset times during the day (see page 8).

Once: In this mode the Heating or Hot Water is turned on at the ﬁrst programmed “On” time of the day, and remains on until the last programmed “Off” time (see page 8).

Off: Heating or Hot Water remains off at all times.

Operation and Programming

Cost-saving programme schedules

The programmer is preset at the factory to turn off your home heating and hot water when they’re less likely to be needed. The preset schedules are shown below. To change them, see pages 912. (See also two alternate schedules on page 25).

To run this schedule (as shown below, or as you’ve modiﬁed it), leave the MODE buttons set to Auto. Y ou can make temporary adjustments at any time (without changing the schedule) by pressing the EXTRA HOUR or OVERRIDE buttons (see pages 1011).

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).
