Combining existing tado TRV radiator setup with new heatmiser UFH.

darahgan

I currently have a tado wireless receiver instructing the condensing boiler to fire up when the TRV temperature sensor says so. My current setup is as shown below.

I'm now adding 2 UFH zones with a manifold controlled by a heatmiser UFH wiring centre. With the addition of the underfloor heating, I would like to use the open-therm support of my boiler to gain maximum efficiency. Below is what i think would work. (Unfortunately, i will have to buy a new open-therm supported tado wireless receiver as the standard UK ones only support relay based control).

In order for the setup in the diagram to work, the tado wired thermostat must be capable of:

• Switching the relay on (to trigger the heatmiser wiring centre to open the UFW actuator and activate the UFW loop pump) and
• Wirelessly calling for heat from the tado wireless receiver (to turn on the boiler over open-therm)

at the same time.

Will this work?

Thanks,
