Honeywell ST699 24hr Programmer
The ST699 is a 24-hour dual zone timer that is designed to replace the programmer on both gravity primary systems and fully pumped systems, with separate heating and hot water temperature controls. It will fit into the same backplate and is easy to programme with a slider switch, which includes plus and minus buttons. Programming your heating to come on as you wake up to a chilly home or return after a hard day at work has never been easier. Our customers find this one of our easiest to use models with no complicated programming to try and figure out.

Easy Peasy - Changing the unit from an eleven year old similar unit with a failed battery pack took less than one minute, aside from re-setting the time clock!
A replacement for one that lasted 15+ years. Hope this one lasts as long.
This controller does what it says on the tin. A direct replacement for a 25 year old which had eventually failed. I won't be here for another 25 years to review the next one.
it is now 24 years since the honeywell st699 time
