Do any of these Smart Rad Valves (TRV) have an external temperature sensor? Only my wife has most of our Rads in wooden cabinets and the current manual TRV’s have a capillary wire to a sensor mounted on the outside of the Rad cabinet. My fear if Smart ones are used they will turn off prematurely due to heat build up in the Cabinet. (I am trying to remove some Cabinets as we renovate as they are inefficient but would be nice to know for areas where Cabinets are part of the rooms furniture).

I'm not aware of smart TRVs with external temp sensors, but one possibly useful thing is that UFH setups typically have the valve and the temperature sensor separate, so if may be worth looking at those.  I've seen UFH systems with hardwired valves (wired off a wiring center, one way for each UFH loop) and wireless temperature sensors, so that could be worth looking into if it was feasible to wire the valves.

Another option might be to simply take apart a smart TRV and put the sensor on a wire. Most of the chips they use for temperature sensing don't use particularly high speed communication, and so hanging them off maybe 10cm of wire would probably work.

Finally, it might be possible to have the smart TRV system ignore the local temperature and use an external temperature sensor - in other words don't have thermostatic control in the valve, have the master controller do it based on the external sensor.  I don't know if any of the smart hubs do that.

Tado offer smart TRVs with a room sensor... the smart TRVs are assigned to the room sensor, all components will need to be on a sub network formed by the Tado bridge gateway

 

that will solve your problem


Professional installer
