Rated 5 out of 5 by from Excellent value thermostat Hadn't realised my old thermostat was failing so badly until I replaced it with this unit. After investigating most of the system I worked out it had to be a new thermostat. This unit fits over a standard junction box, but only just. The instructions give a phone no to obtain a mounting pattress so that the edges of the back box are obscured, didn't try this as old thermostat was much larger so have mounted on a plywood panel until I re-decorate. The unit is very easy to install, set up and use.It also looks good in an older house. I particularly like the display of actual and target temperature - we've enough clocks in the house.

Rated 5 out of 5 by from Great Needed a replacement thermostat for a failed/ancient thermostat (external to Baxi Combi 105e). A programmable one was needed to avoid getting on knees to tweak the current-on-boiler-timings. Old control has 3 wires :- Live (wire1), Heating Load (2) and Neutral ("accelerator heater" whatever that is) (4). These mapped onto same numbered terminals on the Horstmann (more by luck than judgement I guess). Had to provide my own mounting screws for backplate. Removal of backplate from main unit was hard work (there's a side release button) but managed it in the end. Works no problem. Have to program unit next. I hope the batteries last a while...5* price, product and Screwfix. (**remember to isolate mains before performing work.**)

Rated 5 out of 5 by from Centaur 7 My worscester 24i timer was broken/failing. Bought this to by-pass timer. Thought wiring would be complicated but replaced my honeywell thermostat with the centaur 7 easily...actually same two wired system. The programming was simpler than thought.

can I use this model as I have a 3 wire thermostat

Asked by: john2222

Is this control suitable for combi boiler

Have a British Gas (Bosch) 532/i combination boiler with PT5 programmer. the programmer is failing Battery holder looses connection would like to replace with something modern and easier to use.
Asked by: hudsukker
I have fitted to two Worcester Bosch combination boiler systems (my mother and girlfriends houses). One of them because the boiler timer failed, the other for convenience as boiler upstairs. Just leave the boiler set to permanently on and let this thermostat do the work!! No problem with either system. Totally recommend!!

Can this simply replace an existing ordinary room thermostat?

Asked by: Yendor
Yes - can replace any 2 or 3 wire room or system thermostat. I have put 6 of these in my own and relatives' houses. Everyone happy!

Is this item programmable in fractions of degrees, e.g. half or tenths?

Asked by: Xantos
No - full degree only......(which is OK for me as I can't detect half a degree in temperature! )
