Drayton LP522 (Mk4) Programmer 4.2 5 13 13
Brilliant Product Purchased this to replace a faulty programmer. The unit fitted straight onto the back plate with no need to alter wiring. As soon as it was powered up it was operational I did not even have to set the time or day 11 Dec 2014
Compact and versatile I upgraded from an older version and fitting the new programmer was no trouble at all. The 'boost' function is a great idea as opposed to the Advance button. A 24 hr clock rather than the am/pm would have made programming less confusing. 9 Oct 2014
Easy Peasy!!!!! Fitting this was a doddle. I am woman who cant put a plug on! I just upgraded from LP241 and the wiring was exactly the same, The new programmer just clipped onto the wiring that was on the electrical panel in my tiled wall. no screw driver was required only to take of the old programmer of. An electrician would have charged me £50 for a 2 minute job! I upgraded so i could have the use the 'boost' function when I wanted to take the chill of.... 5 Oct 2014
Not my choice Just over two years ago, had the central heating system completely renewed for a top rated system. The contractor selected the drayton controls. Now two and half years later, I having to replace the control programmer as the HW channel failed on timed mode, and the CH channel was already on constant and working thro the thermostat. So without changing the wiring, will have to stay with these, lets hope this one lasts a little longer.. 27 Nov 2013
