I don't know your purpose but this kind of thing is common in industrial systems, including 24V logic being influenced by 110, 230, or 400/440V contactors or other circuit components. In these cases one normally sees an insulated auxiliary contact block(s) mechanically linked with the higher...

Correct, isolate and remove the brown, blue, and grey conductors to the nest. Bear in mind that the terminal X1 will still be live even if the boiler is off locally, there should be a switched fused spur somewhere adjacent to the boiler to isolate the supply. Unless the boiler originally had a...

Also, many boilers have a switched live output for the thermostat, which means when the boiler is powered off, it also powers off the thermostat receiver. Yours does not appear to have this, I cannot see it indicated in the installer manual, looping out the mains as per my drawing will mean the...

Oh if only it were so, alas that isn't even the case in the UK which is the only place the EC holds any official sway. I say alas because like many professional engineers I would love it to be a protected professional designation, unfortunately this has yet to occur in the UK unlike some other...

My comment was about him dissecting another member's, factually accurate, professional contribution. BAS's opinion may have been that the information was above the level necessary for a basic domestic installation, and he is entirely entitled to that opinion and probably correct. But wanting to...

I believe you will need to use the 230V remote timer connection. Can you see in the first picture you posted, the green connector block labelled "X1" where your mains supply comes in, also has a terminal labelled "RT". This is the correct terminal for a 230V remote timer / thermostat. All you...

Sorry you are indeed correct it should be 2 and 3. Good spot. I marked them up as COM and NO correctly in the drawing but used the wrong numbers. Mea culpa. The manual indicates that you want to use the RT terminal on the main connection block where the mains comes in, as shown in your first...

Did you have anything useful to add to the conversation too or are you holding that in reserve... The information is entirely accurate and allows the OP to make his or her own mind up, he was asking for advice on the cable, not stating it had been purchased already, you will note that...

You could use a flush fitting on the ceiling or put an LED batten above the door as you say, I used the batten approach on my airing cupboard light. I would recommend that you have a switch elsewhere on the supply in addition to door switches to remove supply to the fitting in the event you...

Is it this Nest thermostat you are using? https://nest.com/support/images/misc-nest-thermostat-eu/gen3-install/3rd-gen-Nest-Learning-Thermostat-Install-Guide-UK.pdf In which case, page 10 of the manual indicates you should have terminals for Neutral, Live, Common (T2) and Normally Open "Call For...

Cat5e will handle gigabit speeds, the standard specification of course allows for a maximum of 100 metres for reliable Ethernet communication. Cat5a UTP can suffer from cross talk and interference in electrically noisy environments but for most general use is not a problem. If you wanted to...

Part 2 Neo Air Wireless thermostat, 4xAA powered. Lots of different methods of use: Can be programmed individually or linked to Neo hub for programming centrally using the mobile App. Can be used as a stand alone traditional room thermostat linked wirelessly to an RF switch for boiler...

Part 1 I have been looking for some time at various smart heating set-ups and weighing up the different options. I have a 8 Rad + towel rail system on a 32 CDI and I specifically wanted controlled valves on each radiator to allow multiple room temperatures to be configured I was an early...

Looking at your picture it would appear your setup is using volt free contacts, pg 12 of the Hive manual for your original thermostat supports this supposition. In which case referring to Pg 11 of the Tado manual (http://www.free-instruction-manuals.com/pdf/pa_1184115.pdf), your wiring should...

If it's rented I would report back to the letting agent / landlord and get them to have an electrician take a look, if not rented then get an electrician to come take a look. For it to violently blow a lamp under normal operating voltage is weird, when the incandescent lamps are old the bond...

Good news is after writing a complaint email to BG and sending them the receipt and safety certificate from the gas engineer dated the same day as the smart meter install visit they have agreed to refund the cost of the engineer visit.

I was told one of the main reasons they brought in multiple categories was that young lads particularly were passing a test on a little scooter then when they got to 21 or around that age they were getting on something at a 1000cc with no experience and doing themselves in. So now if you want...

Agree with the comment about not buying new, everyone is different but I had two incidents on mine over 4 years, first one someone pulled a U-turn on me, second on I panned it on some diesel going round a roundabout, was annoyed enough without it having been a brand new bike. From personal...

Thanks all will see how it goes. The standard of installation on the electrical side was rather poor too. Not unsafe but just bloody untidy, I don't think a single new component was installed square on the backboard. The bugger also removed a perfectly serviceable Henley block on the consumer...

I've sent them an email, will post back how it goes.
