Adding Electric radiators to Evohome with extra BDR91 Relay and Y87 Stat

[frankmalia]

Hello,
I've built a summer house in garden, and want to use electric heating inside.

My current Evohome Setup Is 9xTRV controlling 9 zones and simple on off boiler control via BDR91 relay to combi boiler.

Can I add BDR91 Relay and Y87 wireless stat to zone 10 and use the BDR91 Relay to switch on the Radiator circuit, obviously via a power relay activating Radiators.

How will this behave with a separate BDR91 Relay, will other zones effect it or it effect other zones. My current 1-9 zones control my appliance relay demand which is BDR91(original).

Will a separate appliance wireless relay appear that is only controlled via zone 10.


Cheers in advance for any help

Frank

Yes you can add a BDR91 as a controller for electric heating. You will find this as an option when setting up your zone 10. I have two zones using the same set up as you suggest and they work independently of the boiler BDR91 and any other zone demands.
