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.
