Wiring Diagram For Valiant System

Help please! I have a completely new heating system installed - Vaillant 630 system boiler with hot water tank, 1 x Tado TRV and 5 zone Tado thermostats. Extension kit and bridge installed and connected in accordance with Tado instructions. The UFH has been connected to the boiler via a heatmiser UH8 wiring centre. The system works but not controlled by the thermostats. Readings go above set temperature. A wiring illustration and guidance re zone settings would be appreciated.
