Rad & UFH set up 2 x two port valves

[jake.taylor]

New to EvoHome products...sorry if this is an obvious question.

Looking to install the following set up for my house.

Understand I would have to wire the two zone valves through the BDR91 relays via a wiring junction box. This would then in turn feed the boiler ‘on demand’
Any pointers would be much appreciated.

Does anyone know if the below drawing would work with the capabilities of the EVOhome system?
