Salus ST620WBC Radio Frequency Worcester Boiler Control

The thermostat was quite a bit larger than I expected. But the good thing is that the display is very easy to read. (Large digits).Installing the boiler part was simplicity itself. I simply plugged in the little plug and clicked the unit into place.The boiler didn't fire up at first; but I correctly assumed that having removed the old basic thermostat, I needed to bridge out the terminals where it was previously connected. (Ls and Lr).The instruction pamphlet covered everything; and I'd got it paired and working within a couple of minutes.As it costs a about a fifth of the Worcester-Bosch unit, I expected it might be cheap and plasticy. - But it wasn't.The thermostat looks stylish - as it's not littered with buttons and switches.There's a very small locking switch tucked out of sight at the bottom right, and two discrete 'buttons' on the control ring. Actually, they are not so much buttons as small indentations. The overall effect is a sleek/uncluttered unit.Selecting the various settings is reminiscent of using the original Ipod. (With a 'ring').I didn't need a set up which programmed the hot water system. - I just wanted a way to remotely control the central heating. - And it does that perfectly.Setting up a week's programmes is a bit fiddly / time consuming (as you have to enter times and temperatures for six programmes per day. But once I found the bit about copying; I realised that I needed only to programme day 1 (Monday); and then copy the settings to days 2,3,4,5,6 and 7.If reading pages of instructions isn't your thing, there's a YouTube vide that talks you through it.It does exactly what it says in the Ad. / It's amazingly cheap / It's brilliant value for money - and looks like something costing many times more.But I guess the best thing about it is that's it's pupose-built for my boiler. Other company's models required two wires into the boiler - and a live and neutral connection from the mains.Whereas this just plugs into the boiler, via a little plug (situated behind the unit).Where for years there was a blank plate - there's now a rather cool looking receiver unit.My boiler was discontinued in 2013, but the list of compatible boilers included it.But I was still a bit worried that it might not fit.I ordered it on Saturday afternoon; and it arrived the next day.So as if being a quality item / being brilliant value for money / working superbly wasn't enough - - -it also arrived on a Sunday!

This was bought as a replacement for the Worcester Bosch mechanical timer/thermostat which I found I constantly had to use just like an on/off switch as it was so poor at keeping a constant temperature.The control unit fitted to the boiler easily, just one Phillips screw to remove and one connection to unplug. The remote unit fitted directly back in the same position in the hall as the old unit using the same screw holes. There was no problem pairing the units. As I am a retired heating engineer I am very familiar with all the various programmers and thermostats that have been used over the last 40 or so years in the industry, and I have to say that this has to be the best and best value unit that I have come across in that time.There have been some excellent reviews describing how to set up the time and temperature settings so I won't repeat those. However I will restate how important it is to site the remote unit correctly (avoid direct sun, away from radiators, not on external wall). Mine is in the hall, which tends to be about 1.5 degrees cooler than the living room, therefore as I want the living room to be at 21.5 I set stat to 20. This give a good temperature for the whole house. Obviously there has to be a temperature differential between the stat stopping calling for heat and the temperature it at which it calls for heat again, in practice I have found it to be less than 0.5 of a degree, compared to the old Worcester stat which seemed to be around 2 degrees!.For the money this is a fantastic unit, certainly as good or better than well known name units of around £150 to £200. the one thing I can't say of course is how reliable it will be in the long run, but judging by the obvious excellent build quality I am very hopeful of a long life for it.UPDATE 6 years later 2022I am just about to change the 2 AA batteries for the second time in six years. I have not had a single problem with this device in in those years. I can only say that all I said above still stands as does the 5 stars. I am still amazed how this is still so cheap compared to other devices on the market.

I had this fitted to my worchester bosch 28 I green star . It works faultlessly. The only small gripe I have is it says the room temp is 19 degrees but it feels like 15. But it does work well all I did was set it to 21 degrees in sted of 19 and its been faultless since. Well worth the money and easy to program.

We have a Worcester Bosch Green Star Combi boiler which was fitted with a time controller and basic RF thermostat. I'd been after a controller like the Salus for ages but they were all too expensive - particularly the Bosch ones! I wanted something that would enable different temperatures to be set at different times of the the day. This controller does just that and at a very reasonable price.This was as easy to install as other reviews, and YouTube clips, have stated. The most difficult bit was replacing the boiler cover! Both items were factory pre-paired so communicated with each other without any problem. The only issue I had was that the RC clock didn't synchronize so I had to initially set the clock manually.Since installation it's been working well. The programmable thermostat feels solid and is well built. The touch ring takes a bit of getting used to but works fine.Just a couple of very minor niggles:-1. I set the time zone to '0' which is what GMT usually is but the next morning the clock was showing one hour ahead! (the remote control clock re-calibrates in the early hours of the morning). After this happened twice I set the time zone to -1 and all has been well since.2. Up to 6 time/temperature changes can be programmed in per 24 hours. I would have preferred 7 or 8. We often feel the need for a slight temperature boost mid evening once dinner is done and we're less active so an extra programming instance or two would have been good.As I say, minor niggles in what has so far proved to be a very good controller.
