BDR91 used for evohome underfloor heating control:

The BDR91 can be used instead of the HCC80R manifold controller, it is simple, each UFH zone is controlled be a BDR91 bound as a zone valve to evohome and a suitable thermostat bound as a temperature sensor.

A relay will need to be added for multiple zones to activate the UFH pump. Please contact us for details.

This set up will work and control UFH exactly the same as using a HCC80R.
