Honeywell ST799 7 Day Programmer
When winter arrives you’ll probably have the heating on a fair amount, especially considering how unpredictable the weather can get in the United Kingdom. But you don’t want to waste money by having the heating on when you’re not around, just so that the house will be toasty warm once you arrive home. Instead, you should use the Honeywell ST799 7 Day Programmer to ensure that the heating is only coming on when you need it.
With this system, you can set the times the heating and hot water system will come on during a 7 day week. It’s a brilliant piece of kit as it’s giving you the flexibility to only use something when it’s needed.
- A simple easy to understand and operate system.
- Can choose between one or two on/off periods per day over a 7 day period.
- Program indicator lights and a 12-hour time display that indicates am or pm.
- Compact in size so it won’t take up too much space on your wall. It can be surface mounted or switch box mounted.
- Comes with a built-in battery backup.
- Can be used on gravity primary or fully pumped systems.
- Power supply: 230V AC 50 Hz

Honeywell ST799 7 Day Programmer ReviewsPrevious
Purchased this to replace old timer that only did 24hr settings. We wanted more control over weekday/weekend timings so went for this model. So easy to instal and set up. Clever copy to other days feature once you have set times for first day. Saves time and settings for days if the power goes off so no need to put all timings back in the device. Very clear backlit display. Easy on off without having to alter settings if heating/water is required outside of set times
Had the older non seven day program version but was basically the same but it appeared a old and tired. We had recently decorated and wanted a nicer looking programmer. The old one was great and worked fine. This one is the same but looks so much nicer being new and in white (the old one was brown000).
Bought this as a direct replacement for my old one - was more expensive than some timers, but gave me the 7 day programmer and fitted straight onto the old backplate - heating working in 2 mins - given the old unit was 20 years old, am hoping this will be as durable...
Purchased the ST799 to replace original timer on Rayburn 480G. Easy plug in swap out with no wiring needed and it works a treat giving us the flexibility of seven day timer. Great price and service from Plumbworld
this was a replacement for a previous c/h timer from the same manufacturer. Performance remains as previous. Expect reliability and quality to be similar. A good extended functionality 2-zone timer. reasonable value.
