Unclear how to connect my Vailiant ectotec pro
Options
Hey all,
I am trying to install the tado v3+ on my heater
It is a Vaillant VCW BE 286/5-3 A R4.
The installation instructions in the app say that the connector on X31 needs to be removed, and another one coming from the translator module has to be attached if present.
I openend it up, but there is no connector on X31?
The previous thermostat that was connected is a VRT 350. The wires where bridged. Nor sure if I should keep that bridge and then connecting it to the + and - on the tado?

This is the circuit board. X31 is in the upper left corner.
This is the thermastat connection how it was, and how it now is.

The VRT 350 uses the same eBus connections that the Tado uses. You should be able to just use the Tado as you currently have it connected, without changing any wiring at the boiler.
