I know I'm not completely daft.
I've removed two 8 year old time switches on towel rail (lighting circuits) and replaced them with Timeguard WiFi Switches. I even remembered how to use my Multimeter to find the live circuit.
But somewhat overconfident I have removed the 5 year old Timeguard NNTO4 timeswitch on the immersion. The wiring was different, see photo.
I have put in place a Timeguard WiFi switch. FSTWIFITU. Identical to the two I've already installed. Wiring different, see photos.
I've no Power to the new FSTWIFITU unit. Dead as a dodo. No glowing blue light.
Multimeter says no live wire blue or brown. How is that possible?
Should I have left Earth Wires capped off?
Is there a mysterious connection or two I'm missing? It looks like the old NNT04 had a link between L and ?
If only the terminology was standardised I have half a chance.... SL? Sin? S Out?
Any help appreciated, please explain like I'm 5.
Thanks
Richard
