UFH and zone valves help?

[Scott_D]

Hi all
Got an existing combi with 3rd party controls.
There is a towel rail zone with 2 port valve and UFH manifold with 4 actuators and a 2 port valve.
They are having an extension with another UFH manifold with 3 actuators, would this need a 3rd 2 port or just use the same as the other UFH?

Depends if they have programmable stats on the existing manifold / independent control on the new one etc

I think its a room stat per UFH room zone
