Hi, would like to ask if the boiler Bosch Condens GC 2300i W - is it compatible with the tado and how it is possible to conect it? do you have any manual? thak you Peter
This is not a customer support desk, you need to contact the Tado servicedesk for questions like that.
It is definitelly possible to connect it using on/off relay. Unfortunatelly It doesn't seem possible to connect it using EMS as this boiler utilizes EMS2 (not supported yet by tado).
It may be possible to use an EMS to OpenTherm convertor (https://www.robbshop.nl/nefit-ems-opentherm-converter) but I'm not 100% sure.
You can install Tado Pro app and type the boler name and see the wiring diagram. I just looked into your model and It is clearly just relay on/off.
Buy a Bosch CT200 !!!
