Drayton wiser smart hub and ufh wiring centre

[Singloon]

I’ve currently got a Drayton wiser hub 2 channel for heating and hot water.

I’m looking to install hydronic ufh (3 zones) and would want to use the Drayton ufh wiring centre. So it can all be controlled via the same app.

Would I need to get a new Drayton wiser hub with 3 channels or can I use the existing one?

Hey Singloon, Did you ever figure out whether it is possible to retain the existing hub where all channels are currently in use in this scenario? I am in a similar situation with an existing Wiser 3 channel(2 heating, 1 HW) hub and have underfloor which I would like to control with the underfloor heating controller in addition to the existing zones. The docs you attached has the following note on the wiring diagram If you are installing a system with only underfloor heating (no radiators) you can select in the Wiser Home app to control the boiler using the Wiser UFH Controller boiler output OR the heating output in the Hub R which seems to indicate that the UFH Controller can be controller separately to any existing channels in the hub but I would like to confirm this.
