Worcester Greenstar 34CDi Boiler compatibility with Evohome

Post by eroir »

Hi all

I am planning to replace my ageing boiler with Worcester Greenstar 34CDi Classic ERP Combi Boiler and I am planning to start building my Honeywell 'Smart Home' environment. First of all I was wondering if someone let me know if this boiler will be compatible with Honeywell Evohome smart heating controller including HR92 Radiator Controllers?
I was trying to find some info on Worcester and Honeywell websites but the info is very generic and it doesn’t tell you e.g. yes it is compatible or no it is not…

Many thanks
Eric

The Worcester 34 CDi will run with the evohome system as a Class IV (TPI) controlled system, but won't do load compensation (Class V).

I Hope that helps.

Many thanks for your reply. Now after additional reading on web I know the difference between Class IV & V :)
I guess future firmware update for Evohome controller may resolve this...
