    2-gang light switch - 2 common feeds?

    Hi So I am planning to replace my living room light switch with a smart switch such as this https://www.diy.com/departments/wifi-smart-2-gang-touch-switch-no-neutral-needed-black-body/5060774555408_BQ.prd?alt=true The existing switches have 2 gangs (for 2 lights) - each with T&E to the fitting...

    Integral garage wiring

    Thanks all. The ring is on modern CU so has RCD protection. Is that sufficient or do I need additional for the garage, e.g. FCU (not fused JB ) with built in RCD? It's in the garage where the boiler and cylinder are located. Not looping in and out of the garage. Makes sense. I may at...

    Integral garage wiring

    Hi So recently moved into new house (early 1990's build). I'm wanting to fit an extra socket to my garage (integrated). Having looked at the wiring in the garage, it's fed off a spur from the ring main in the lounge through the wall. So the spur goes to a single unfused socket. That then...

    PIR sensor voltage - Scantronic 9751

    So I found the issue. There was no voltage drop seen at the aux connector on the controller, only at the junction box and the PIRs. Turns out to be a fault in the multicore between the controller and the junction box - high resistance on a couple of cores, including red. Have now repurposed a...

    PIR sensor voltage - Scantronic 9751

    Will try with battery removed when I get home later. It's in multicore (8 core I think) cable, no steel. It's powering 4 PIRs, but get a drop even with just one connected. PIRs are rx40-qz. Cheers

    PIR sensor voltage - Scantronic 9751

    Not a zone expander, just a small box of screws to tap off. There's +12v, GND and 2 zone connections from the controller to the box, then the 12v feeds to the PIRs taken from here - and the switch loop in series. It'll be up to about 10m to the junction box, depending on how the wiring has...

    PIR sensor voltage - Scantronic 9751

    Hi So I have the above system in new to me house, and have been trying to trace false alarm triggers. Voltmeter over the feed of the PIRs shows only 8 volts. Have traced wiring back to junction box. Breaking the connections apart I get 13.6 volts from the controller feed. As soon as I wire...

    Opentherm with S Plan System

    Thanks stem After a bit more reading around this forum last night, I saw that suggested improvements in energy savings are only a few percent (seen 1-2%, 6%). Also some suggestion that manufacturers are removing OpenTherm from newer boilers, so whilst it sounds "shiny and new" it's been around...

    Opentherm with S Plan System

    Hi Can anyone advise how Opentherm wiring should work with an S Plan system (1 heating zone)? I'm looking to add smart control and was going Hive but learned that my boiler (Logic+ Combi 24) supports Opentherm so that might be a better option and lead towards Nest which supports Ooentherm...

    Vokera Excel 80SP Service and Repair

    Hi All I have a Vokera Excel 80SP Combi boiler, it's not been serviced for a few years. Last time I had an issue with it I had lots of problems, and got a fixed price repair from Vokera who replaced all sorts (boards, expansion chamber, valves, etc etc etc) and it's been great since...
