The ESI 2 Channel multi purpose programmer can automatically switch your central heating and hot water on and off up to 3 times a day, whatever times you choose. Timekeeping is maintained through power interruptions by a non replaceable battery designed to last for the lifetime of the programmer and the clock is automatically put forward 1 hour at 1:00am on the last Sunday of March and back 1 hour at 2:00am on the last Sunday of October. The clock is factory pre-set to UK time and date, but you can alter it if you wish. Buttons normally visible, only affect your set programme temporarily. All buttons which can permanently change your programme are located behind the flip over facia.
