Hi, Any help or guidance appreciated. I’ve moved into a property with electric UFH in the bathroom, controlled by a Devireg 550 controller. The heating works (mat comes on warm etc) but the control is partially broken and the control knob doesn’t work. We have UFH elsewhere in the house running...

Ah, OK - this makes sense (I think!). So I hardwire the existing wired stats so they bypass the programmer all together - these are permanently live on one side. The wireless Tado system (plus receiver) would then replace the existing WiFi receiver and have HW connect to this too… corresponding...

Thanks RandomGrinch. There are neutral wires present (disconnected) behind the stat but my electrician/plumber is not being particularly helpful in tracing where they go (I presume behind the programmer but it’s beyond my skill level). I have been thinking Tado (have prior experience in a much...

Wow, very detailed explanation - thanks! To answer some of the questions Heatmiser system is the NeoStat v3 and are all connected to the NeoStat hub - this works fine and is independent from the older (radiator) system - it is linked directly to boiler so bypasses the old programmer and...

Hi All New member here but wonderd if anyone had experience in wiring up the LightwaveRF smart Relay switch. We have a Grundfos Gold Pump whose job is to constantly coirculate HW around the house. This was on a timer which has since broken so the pump was constantly running and wasting HW. I...
