New Install Help..


Hi All

I've just installed Smart Thermostat V3+ Starter Kit and I've got an issue where the boiler (Vaillant ecotech pro 28)

replaced a Danfoss wired Thermostat using 2 wires COM/N0

The 2 Radiator valves work fine but the boiler is running all the time, I have everything switched to off on the app and its still running flat out

Grateful for any help
