Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from Easy change from the old one Industry standardisation of the back plate makes this an easy un-clip and install, programme and forget. The back light makes adjustment much easier as these are often sighted in dark corners. On this occasion I did install the new back plate as the old one was showing signs of oxidation of the connecting pin sockets. 4 stars overall because it does what it is designed to do which in my mind is not exceptional...that should be the minimum expectation. Reliability untested as yet but expect no problems as the last one went for 12 years.

Rated 4 out of 5 by from lp241 our original one broke down, leaving us with no hot water and heating for the week end, luckily screw fix had one in stock in our home town, easy to fix in just a matter of undoing two screws and placing the new unit on and doing it all back up, well done screw fix,
