Replacement for Honeywell CM927

Hi,

Does anyone know what product is a good replacement for a Honeywell CM927 wireless thermostat controller and BDR91 Relay Box that controls my electric underfloor heating?

I assume it needs to be another Honeywell product and the T4 wireless thermostat which seems to be the latest model, but I haven’t found any guidance on whether it’s compatible with electric underfloor heating.

Thanks in advance for any advice!
