Rated 5 out of 5 by from Just the job I purchased this programmer for a customer who had the previous ST6400C programmer as an integral part of their Stanley Cooker/boiler. It was a bit more expensive than going elsewhere but it's Christmas, Screwfix had it on the shelf at a branch, so I could get the job done before my customers visitors arrived. They were more than happy to pay the small premium. I have fitted these programmers before so can give it top marks for features, reliability etc.

Rated 5 out of 5 by from Replacement unit Had a problem with my old controller. Either provided hot water or central heating. My heating engineer came out and recommended this unit. Said it would be easy for me to fit. He was right. Two screws to loosen, replace unit onto original backing plate and re-tighten screws. Five minute job. Now have perfect system and increased programming options.

Rated 5 out of 5 by from Complicated but good This programmer is not for the customer who wants a simple on/off clock, it has all the features for a domestic household who need to program their heating daily. Easy to install, wiring easy.

Rated 5 out of 5 by from All good Firstly I've only had this item a couple of days so the reliability score is, ironically, not that reliable but hopefully it will be accurate. It was purchased to replace a second Drayton LP722 programmer which failed within 6 months, the previous one only lasting 2 years. Hopefully this one will have a longer lifespan. Mounting plate compatible with the Drayton so it was an easy remove and replace, no wiring to be done. Honeywell provide a compatability chart on their website too so you can check. The programmer has plenty of functions and features like boost times and holiday modes and it was a doddle to set up. It seems well built and worked straight out of the box.
