The ESi ES3247 is a 3-channel programmer designed to control central heating and hot water systems. It allows users to set 'On' and 'Off' time periods for up to three channels (Central Heating Zone 1, Central Heating Zone 2, and Hot Water), up to three times a day, at user-chosen times.
The ES3247 programmer automatically switches your Central Heating and Hot Water ON and OFF. It maintains timekeeping through power interruptions via a non-replaceable battery designed to last for the lifetime of the programmer. The clock automatically adjusts for BST/GMT time changes (forward 1 hour on the last Sunday of March at 1:00 am and back 1 hour on the last Sunday of October at 2:00 am). The clock is factory pre-set to UK time and date, but can be altered.
During installation, the installer configures the programming options via a 4-position DIP switch on the back of the unit. These options include:
The programmer features a large, easy-to-read display for programming. Buttons normally visible on the front facia only temporarily affect the set program (e.g., Advance, Boost). All buttons that can permanently change the program are located behind a flip-over facia, preventing accidental changes.
The unit offers several operating modes for each channel (CH1, CH2, HW):
The first screen displayed when setting time, date, or changing program times indicates the unit's configuration (e.g., 2PU, 3PU, 2Gr, 3Gr). This also shows how the Monday to Sunday indicators are displayed, verifying the 24-hour, 5/2-day, or 7-day programming option.
