I have a Myson wireless UFH control system 230V with 4 of Myson/Danfoss FH-RT wireless thermostats in 4 zone UFH system utilising a Grant ASHP. The FH-RT thermostats are now unobtainable - to avoid changing the whole system out has anyone a suggestion for a replacement wireless thermostat?
Seeking suggestions for replacement for Danfoss RH-FT wireless thermostat as unable to obtain failed unit

Not entirely sure what you mean there, I don’t have ufh experience. Wireless thermostat’s use their own frequency afaik.

The Danfoss units work at 433mhz but others seem to be 868mhz and therefore any proposed replacement must be 433mhz, which I have been unable to locate and hence the question I raised. Danfoss support appears non existent as they won’t answer emails.
Many thanks for input. For sure Danfoss will be closed for Xmas but they acknowledged the enquiry on the 5th of December and I'm afraid I need to keep progressing this even when they don't answer. Your picture is accurate and is the unit the Myson appear to have badge engineered for resale. We bought the last 3 thermostats available in 2017 for myself and 2 neighbours and am now seeking alternatives with failing existing units.
The existing wireless thermostats are identified by the receiver in the FH-BU unit i.e, only the thermostat is needed, as the receiver is integral to the FH-BU
