Salus RT300RF Digital Electronic Thermostat with RF

Very good bit of kit if you want to be able to move your room thermostat around the house or around a room to find the best position and/or to later change location to suit radiator upgrades or house extensions etc. If not there are digital room stats out there without the radio connection capability of this one or the extra cost albeit cost of this one I felt was v.good value at £31.58 as compared to daft money for some others out there. There are two separate parts involved - here I will call them "sender" (that's the bit you can move around the house wirelessly) and "receiver" (that sits somewhere permanently wired into the central heating control scheme but which must be within communication range of the sender). My receiver is sat quite happily in the airing cupboard of my 3 bedroom home quite near the hot water cylinder, central heating pump and a plethora of water pipes - the sender communicates happily with the receiver if the sender is put in anywhere in any room indicating the signalling between them is a reasonable standard. Only got one gripe and that is that the included table stand has no tilt adjustment and so as standard the sender sits on a table at approaching a 45 degree angle meaning the LCD cant be read easily from more than around 6 to 8 ft away from it. There is a built-in wall hanging facility but its kind of defeating the object of its wireless nature to fix it on a wall. Very simple to use and I found Salus excellent from tech spt line view point (response and helpfulness) when contacted to see best way to connect it in place of a traditional 2 wire hall located room thermostat (original thermostat now in bin and a nice clean wall where it used to be). Those same 2 wires were simply disconnected from the 2 (of many) terminals where they were connected in the central heating controls wiring box (not the programmer) located in my case in my airing cupboard and the same 2 terminals of that wiring box were then connected to a new flexible cable the other end being connected to the receiver units volt free contacts. Via the same new flexible cable and rom the same wiring box, a 230 volt ac supply was also taken and connected to the L(ive) & N(eutral) terminals of the receiver unit as it needs a mains supply that is permanently on (ie unswitched) but which can be isolated using the same isolation means as should be in place already for the complete central heating control system (in my case the isolation means is a switched fuse unit (3 amp fuse) in the airing cupboard nearby the aforementioned wiring box. Its a doddle to install and use and has excellent Salus tech support if help needed which in my case I needed to do to establish connection options for it relating to my particular central heating system and also because the product did not appear to work immediately after switching on for the first time (another minor niggle - but it turned out to be normal until the sender has self registered to the receiver and this took a few minutes after which it has worked without any issue - possibly something Salus should explain in the manual). Ive given 5 stars as its not possible to give 4.5 and 4 is too low but 5 too high because of the one or two niggles referred to above.

Item arrived promptly and was (fairly) easy to install. I find the design a bit odd though - the wall mounting plate for the receiver has no cable access and only serves to hold the unit to the wall.The receiver is released from the wall plate by loosening two screws at the bottom edge, allowing the unit to hinge away from the wall and unhook at the top.This means the cable also feeds directly into the bottom edge of the receiver and therefore *must* be a flexible cable (rather than solid core) to allow the unit to be fitted and/or removed for inspection.This makes it a little cumbersome - as does the need to be able to get at the retention screws at the bottom - i.e. if mounting this above another electrical socket or (more likely) a central heating controller, be sure to leave a big enough gap between the two.One other note of caution. The terminals use a screw clamp action which holds the wire better than a simple "terminal block" style screw would (and does less damage to the conductor) *BUT* this also makes it possible to get the wire *behind* the clamp instead of inside it. This means you can tighten all three terminals fully and not realise than one wire is not actually secured in place.The need to hinge the unit away from its mounting whilst working with a short, flexible cable makes this even more likely. Throw in any physical access difficulties (like mounting the receiver in a tight spot above a corner-mounted boiler for instance) and you could find yourself chasing a non-existent CH controller fault for 3 hours (I speak from experience).All that said, once the wiring error had been corrected and the receiver had been installed everything worked perfectly.It's been running ok for about 6 weeks now and I haven't had any of the wireless interference problems other people have mentioned.The room thermostat seems pretty responsive. Temperature needs to hit 0.5 degrees above or below the target temp for the boiler to be switched off/on but that seems fine (it could hardly be expected to work with no margin or the boiler would be constantly switching in and out).All in all a decent product which did the job at the fraction of the price of the Honeywell device I was originally looking at.

Was brought for my mum who had a wireless thermostat fitted when the central heating was replaced, but the one they fitted, even I couldn't work it out. However with this, it is very easy to understand and very clear to read. This was the first wireless one I had fitted. The thermostat end was the easy bit, but when fitting the wireless receiver, had a few problems understanding what wire needed to go to what terminal. However, after some comparison to the one already fitted and following logic, was able to work it out. Thermostat linked to the receive straight away, but changed the frequency, just in case a neighbour had a similar device. After many days of use, received the news that all is working well and so far is maintaining the temperature of the house really well. Would really recommend this to anyone who just wants a simple thermostat without any need for 7-day programming. Many thanks for a great product.PS. Have the hard-wired version myself, and is working great after many years of service, so should expect the same for this.
