Drayton LP522 (Mk4) Programmer is rated 4.3 out of 5 by 38.
Rated 5 out of 5 by from Excellent easy to install! I bought this programmer to replace an older Siemens programmer, the terminals were easy to connect wires to, it was very simple to programme the on and off times for the customer and was simple to show them how it works Definitely recommend

Rated 5 out of 5 by from Highly recommend I bought an LP522 earlier verson 10 years ago and it has worked reliably ever since, but like all things finally needed replacing this week. Next day delivery, fitted in 5 minutes to the existing back plate and 5 minutes to change the standard programming. Pretty good and I see the mk4 now has a boost and holiday setting. Pretty good yeah!

Rated 5 out of 5 by from Straight swap. I had to replace my old Sunvic controller quickly. This pushed straight into the same backplate and was working within 2 minutes. It has 3 On/Off times, a backlight and even a holiday mode. Absolutely brilliant for the price!

Rated 5 out of 5 by from Excellent Programmer I bought this to replace an out of box failure of a Honeywell programmer. This Progammer is very easy to program and was fitted and running in 15 minutes. Really pleased with this purchase and will recommend them to future customers.

Rated 5 out of 5 by from Ridiculously easy to install. Bought it to replace my old one as one of the buttons got stuck due to age. Installation is super easy. It fits into the same back wall panel so you never need to touch any wires at all. No need for electrician it is SO easy. Simply unscrew your old box which has two screws at the bottom. The old box slips off the bracket, slip the new one on and that's it! Programming is simple and straightforward... The 'Holiday' setting is an extra bonus where you can turn your HW and CH off for X days while on holiday before it automatically clicks back in
