Wireless Receiver X wiring question

Hi all,

I'm trying to wire a Wireless Receiver X to a Rehema Avanta. At the moment a Honeywell receiver is attached, see picture of current wiring below. If I understand the Tado-app correctly, I have to replace the blue wire with the black (terminal 3) and the brown with the grey (terminal 4). Can someone confirm this?
The app says to make sure there is no bridge between the terminals I connected to, but what about the bridge between terminals 1 and 2? Do I remove it or leave it in place?
Any help would be greatly appreciated!

Cheers,
Steven

    What is the exact model of Rehema Avanta and the exact model of Honeywell receiver?

    The Rehema Avantas seem to operate in both relay mode and in Opentherm mode. However the circuit boards on each model are specific, unique. So need the exact model to identify how the wiring might be handled.

    Have you contacted Tado support with this model information and asked them for specific instructions? In any case, come back here, will try to help.
