ESI ES1247B Single Channel Multi Purpose Programmer Timer (New Model) by ESI Controls

Bought this timer for oil heating boiler as it is the same as my older one easy to install as you don’t have to wire it up just unscrew old one off as the backplate with wires stays on the wall & just click new one on to plate all ready to go setting times for heating

Easy to install and the price is reasonable. So far no complaints, works well.

Simple to use

Replaced an older Randall 103 timer with this unit. Hardest bit was sorting the older wiring out. Easy to install the backplate and set the timing. Be interesting to see how it holds up over the winter. Its early days but doing good for now.

The timer is very good at a reasonable price but the only minus is that I wasn't aware that it didn't have a hot water only facility.

Easy to use

This boiler timer is perfect for anyone who like to have the heating come on at different times on different days of the week, for example different time for weekdays to weekends.It’s really easy to program as long as you follow the steps In the manual.You are able to easily set up holidays, and the boiler will automatically return to normal operation when the number of days selected as holiday expires.So many functions - perfect for a modern household!

Supposed to have an industry standard backplate.It didn’t fit the backplate on my existing Horstmann Centaurplus time switch.Also the wiring was different.
