"We purchased this control unit after moving into a house with a Drayton/British Gas branded controller which only had means to turn on hot water and heating simultaneously.
The LP722 can control each independently which allows hot water to come on briefly and heating to stay on in the evenings and be controlled by the room thermostat.
As a swap it was the simplest DIY job I think I've ever done apart from changing a light bulb. 2 screws and about 10 seconds later the new unit was fitted since the backplate was identical. The new unit has battery back up and is even preset with the right date and time and default control programs.
We had a similar Drayton unit work flawlessly at our last house for 7 years and I know others with similar Drayton units lasting ages so we have no reason to suspect this won't do the same.
One last little thing this unit has softer green LEDs, the BG one had red so this one wins a minor aesthetic point.
Value only gets 3 stars since I'm sure there's only a minor programming difference, not sure why it's £10+ more than the simpler unit..."
"I bought this to replace my 16 year old LP522 which sadly passed away without warning at 6pm on one of the coldest days of the year, no time to lose I ordered on line and picked up a new LP722 from my local Screwfix, which slotted straight over my existing connection plate, in two minutes I was up and running, I didn't even need to set the clock. Easy to use, simple instructions, what more do you need."
"The programmer had all the features for complete control of my heating system and as it uses a standard backplate no rewiring was required just two screws unit was fitted in one min battery backup meant no need to set the time the only settings needed was if your personal preferences differed from the pre-sets already programmed in"
"Bought this to replace a failing LP522 due to battery - a bit disappointed as the old one had only lasted 16 years!!!!!
The extra functionality is really great and for the price exceptional value. It took about 3 minutes to replace and the time and date were correct straight away and it automatically adjusts for BST/GMT.
"I bought this to replace a failed unit. Main reasons for my choice were; direct replacement with no need to change any wiring (helped by the good documentation that gave equivalent replacement / wiring). good recommendations on the screwfix website for this model. Value for money."
"I bought the Drayton LP722 Programmer on August bank holiday to replace my mothers faulty Honeywell ST6400C. The Honeywell had only lasted 2 years, and the previous programmer the same Honeywell model a similar amount of time, neither of which were supplied by Screwfix. I am a heating installer/engineer and have noticed a reliability drop in some Honeywell products, so I opted for the Drayton as it's replacement. The features are similar in both makes, there's not much between them except the Honeywell is more aesthetically pleasing and costs about £26 more than the Drayton at Screwfix. The Drayton keeps the facia layout simple with the controls hidden under a flap, the instructions are easy to follow for wiring and programming using the select for heating or hot water, set, + and -yes buttons to make choices and copying for subsequent days. Installation and programming in this particular instance took 20 minutes, removing the old programmer, drilling new holes in the plasterboard wall, fitting the new backplate connecting the programmer supply and load wires which were all laid out the in the same orientation as the Honeywell except the earth which was in the opposite corner of the backplate. Myself I did not need the instructions to programme in the separate times for hot water and heating as having installed Drayton programmers and many other different makes of programmers in the past it is easy to navigate around the simple menu. I can honestly say I have never had to replace a faulty Drayton programmer or time switch of any model in all my time as a heating fitter, so I have given it 5 stars for reliability. I won't be using the Honeywell ST6400C again as there seem to be quality and longevity issues surrounding that programmer, it probably wouldn't be out of place on the shelf of a pound store obviously priced at £1! Drayton -1 v Honeywell - 0"
"Very easy to fit, clear instructions. Was very surprised to see that the clock and date were already acurately set when I got it out of the box. Also like the summertime auto adjustment (one less clock to worry about). Easy to use and program. As for reliability, it is difficult to tell as I have only had it for a few weeks. I have a Drayton wireless thermostat that has been in use for about 7 years and that has never let me down so I am hoping for the same from this programmer."
"Bought this for my mother as a replacement for one that a plumber installed and she couldn't work out. Wired it straight in and it set itself. Made a few time adjustments and it's been spot on, even she can operate it!"
"I've had this controller for some 21/2 years and I've the same problem as another reviewer. The HW relay sticks on and blocks the CH coming on. If you tap the controller you here it click and the CH can start. I recall having a similar model in a previous house. Exactly the same problem occurred but thought it was a one off. I'm going to see if I can get a replacement relay because I don't want to spend £66. I'm not buying a Drayton timer unit again. The only problem is finding a reliable one."
