Wiring up extension kit. Boiler doesnt fire up
Ive been running the old V1 Tado for years without issue, recently the thermostat started playing up so I bought the newer Smart Thermostat starter kit and today I received the extension kit.
I had hoped it would be a simple swap but as always no such luck..
I can control the heating by pressing the extension button twice, the relay clicks and it fires up.
However, if I attempt to fire up the heating using the smart meter OR the Android app nothing happens.
I have attached a photo of the wiring which is as Tado Support told me to do it, I have the link set to No 2 also as I was told.
ALL devices are setup and working in the app.
Does anyone have any ideas on this? Im expecting to wake up cold in the morning :(
