Rated 4 out of 5 by programmer easy to install bought the lp241 to replace my old honeywell programmer. The installation was easy and the product works well. Problem is that its less than a week old and reviews of this type of product all indicate that the problems are with reliability so too early to comment. Good so far. 8 Jun 2016
Rated 5 out of 5 by Does what it say's on the tin I purchased this as a direct replacement for my old control unit and was amazed that it was still being produced ! it was so esy to fit ! straight swap, and i am no tradesman , buy with confidence the last unit lasted 20 years + so hopefully this will be the same Also easy to use and program, with a very good one button push for heating or hot water boost if your between programs 21 Jan 2015
Rated 5 out of 5 by Drayton LP241 (Mk4) Programmer Very good dependable product. Used to replace an 8 year old one that had been mistreated and damaged. Direct replacement is so easy, just 2 screws to loosen, take out the old and clip in the new. Job done. Also the Mk4 has additional features over the old one. Ordered then delivered next day on site FREE. Can't get better than that. 15 Jan 2015
Rated 5 out of 5 by Boiler Control Needed a Replacement Boiler Control. I was concerned that I might need to change the wiring from the Old Control to a suitable Replacement. All the Information was available for this unit and I was able to replace it directly. This was so easy and neat. I did change the back plate but this was not essential. The existing one would have worked but just wanted all new parts. My wife finds this easy to programme and is pleased with it.. Need I say more. Has been working great since installation. 30 Dec 2014

The advance moves the time onto the next setting. The Boost function allows a boost of 1,2 or 3 hours from the time it is activated.
