Replacing a Honeywell Evohome with Tado - Help with wiring



I am replacing a Honeywell Evohome with a Tado and had some questions on the wiring. It is connected to a Worcester Bosch Greenstar 42CDI Classic ErP Combiboiler.

This is the current wiring of the Honeywell BDR91

Would I use the following wiring diagram for Tado to retain similar functionality?

Thanks for your help.


  • Hi did you solve this? As im looking to replace my evohome system had enough of it
  • It looks similar to above diagram, anyway just replaced mine and Tado wiring guide during setup was spot on.
