Wireless Reciever EU

MaxRebo

Hello

Tried to wire in the wireless receiver EU version to my Vaillant boiler using the bus + & - connections from the Boiler to the receiver but the receiver was totally dead. Tado have informed me I also need to wire in the L & N just asking if anybody has wired in the EU receiver like this

Yes, you need a separate power connection for Opentherm.

Thanks for the reply does that also go for the Vaillant bus connections

Some ebus connections do, some don’t. If the receiver is dead and Tado is saying you do, I’d say yours does need a power source.
