Drayton 123070 LP522 (Mk4) 2 Channel Programmer, White

This product arrived from HRH solutions within two days of ordering and well before the first delivery date quoted. It was to replace an LP112 which does not provide for different timings for hot water and central heating nor for different timings weekdays and weekends. The LP522 caters for both sets of differential timings, so long as you have a fully pumped system (rather than a gravity system, in which case the hot water is automatically on when the central heating is on). The LP522 has the same backplate as the LP112, so unscrewing the LP112 and removing it, and replacing it with the new LP522 took just a matter of minutes, with no need for any rewiring. The new programmer has the time and date automatically set at the factory and the correct time showed up straight away on switching the electricity back on. Programming the timings on the LP522 was very straightforward as well, and there is ample opportunity to go back over your choices if you get something wrong. With three separate on-off timings per day, it gives a great deal of flexibility on when you choose to have your central heating and hot water on, thereby potentially saving you a lot on your gas bills. So far, it has been in operation for a couple of weeks, and it has proved very reliable.

My Lifestyle CH/HW programmer, after 25 years(!) began to look incredibly tired and was not retaining the desired programme. £65 and 18 hours later the replacement arrived and it took around 30 minutes to fit. It should have taken no more than 5 minutes but the wiring patrice broke when removing the programmer - doh! Anyway, it's a really easy job to update an ageing programmer and this new one has made setting the times and frequency of my boiler much nicer! Would recommend.

Great product and considerably cheaper than the one it replaced. Easy to fit and to programme. My only concern is that in order to install correctly you have to set a jumper pin on the rear of the box depending on if you have a pumped or gravity fed system. Not obvious (to me at) first and my installation failed to work. Soon sorted when I had another look at the instructions and realised what I had overlooked. But, It would have been better to have had this crucial step "Highlighted" in some way.

This was (is) a direct replacement for a faulty Drayton 2 channel programmer. I just turned the power off, unscrewed one connector screw on the underneath, then unclipped the old one and clipped in the new one. It was as simple as that, no plumber/electrician required, just a like for like replacement. I would recommend this to a friend.

Bought to replace my old Lifestyle LP522 programmer, this is an upgraded model with 3 on/off cycles instead of the 2 on my old programmer, and the addition of a "Holiday" programme which should come in useful. Fitted in 10 minutes by after reading full instructions provided. Simply switch off the electricity then unscrew 2 screws underneath the old programmer and lift it off the back plate, then push the new programmer onto the old back plate. Dead easy, no technical knowledge needed. Excellent product if it continues to be reliable.

If like me, you want this to replace an existing LP522, because of the battery backup, then it's ideal. The previous model didn't have the built-in battery, and always lost its settings in the event of a power outage.Don't bother calling a heating engineer, because anyone can install this timer. You literally undo a couple of screws, and lift it off the back plate. Then just fit the new one on to it. Simples! The wiring is exactly the same as the previous model LP522.Nice price too, anywhere else on the web this costs at least £60 plus postage. How on earth do Amazon do it?!I'll knock a star of 'Easy to use', because setting this thing is a bit fiddly to program, but it's quite logical so persist with it.

Quick delivery, excellent price and works exactly as needed, therefore five star. Just a note for anybody installing themselves. Unit fits onto the old backplate (although a new one is also supplied) BUT BEWARE if the old unit is hard to remove, as mine was because it had been painted-in over the years, DON''T unscrew the holding screws all the way out or you will have to take the old backplate off the wall to get the nuts into a position that the screws can be reinserted. I don't think that the instructions tell you to only loosen them but maybe they did and I didn't read them correctly.. Anyway my fault entirely and it turned a five minute job into a good bit longer as the old backplate was well embedded into the wall!

I expected a like for like replacement, while it was similar it wasn't exact and has a mind of it's own I keep having to many switch off. I've had an electrician friend who reset to my request, yet it still has a mind of it's own. I'll try to reprogram over the weekend.It's important to note this is my personal experience, other buyers had a good experience.Delivery was timely and well packged.
