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.

    It shouldn't be so unexpected but sadly it is! How often do you find an entire piece of kit has to be replaced when one element has had its day? We needed a new programmer when our previous Honeywell ST699 of the grand old age of 30 years, began to play up. I was delighted to find the same product still available - and what a fantastic low price on Plumbworld! - and over the moon when I found that the newly purchased front section would fit the original back mount. All that was needed was to click the new front into place on the old back and hey presto - problem solved! What a joy!

    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!
