Wireless Reciever EU


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.
