ESi 3 Channel Multi-Purpose Programmer E3247B

The Sangamo ES3247B is a digital 7-day electronic time switch designed for precise and flexible control of electrical loads in domestic and light commercial applications. It is commonly used for controlling lighting, heating, pumps, and other fixed electrical circuits where timed operation is required.

Featuring a clear LCD display and simple push-button programming, the ES3247B allows users to set multiple on/off switching times across a 7-day schedule. This provides full flexibility to match occupancy patterns, helping to improve energy efficiency and reduce unnecessary running costs.

The unit offers both automatic and manual override functions, allowing users to temporarily switch circuits on or off outside of programmed schedules when needed. This makes it highly practical for everyday use and maintenance situations.

Designed for installation in a standard electrical back box or DIN rail enclosure (depending on configuration), the ES3247B is suitable for a wide range of retrofit and new-build applications. Its compact design and straightforward programming make it a popular choice for installers.
