Have a zone with BDR91 and HR92 in it?

[Secret_squirrel]

I have a kitchen with a single radiator and a plinth heater in it.

The rad has a HR92 on it I realised I could switch the plinth heater with a bdr91 and a contactpr to handle the current with a remote T87 thermostat to monitor the temp.

All went well in the fitting apart from having to put the evohome controller in the kitchen so it could see the bdr91.

Right now I have the kitchen radiator on its own zone controlled by its internal temp sensor and a second kitchen zone of type Zone Valve using the Evohome controller as the temp sensor.

For simplicity I’d like to have a single zone that includes both the rad HR92 and the BDR91 though - is there a way to do this?

No, unfortunately Radiator Controller zones cannot be paired with a BDR91. Is it an electric plinth heater you have or hydronic?

The way I would have done this if it was hydronic, is to put a HR91 Radiator Controller on the return pipe of the plinth heater with a straight TRV valve, and paired both devices into the same zone controlled by a T87RF.

There are alternative ways if you use things like Home Assistant, but not natively on evohome.
