Years ago we were always told, you don't fit a TRV in same room as the wall thermostat, well that has clearly all changed.
To date that is the only thermostat where I have seen instructions on how to set, in fact only one where I have seen a warm up time option.
The big advance in my eyes is having °C marked on the TRV, not more silly *123456, but it seems how the TRV works with the wall thermostat varies a lot, and I am not impressed with the MiHome Energenie method, having the TRV follow the wall thermostat seems to me the wrong way around, Hive idea seems better where the TRV tells the wall thermostat to run boiler even when the target temperatures has been reached by wall thermostat.
Nest wall thermostat was suppose to work like the MiHome Energenie one, however the support was withdrawn, it does work of sorts, but not reliably. The TRV will some times follow, but not every time.
EvoHome will it seem not work without TRV heads, but not sure on this? But it does seem to have been one of the first fully integrated systems, but the Hive allows one to slowly add, rather than buy all together, which is what I tried to do with Nest only to find support withdrawn.
So my TRV heads are set to same schedule as the wall thermostat, but not linked, as yet not tried setting the TRV heads to geofence, the Nest wall thermostat does, and also has occupancy detect, so if family in the house it will not shut down.
I feel I wasted money with MiHome Energenie as they can't be manually adjusted, so if I walk into a cool room and phone is not in my pocket then it seems can push button and I get 21°C for one hour, the default is 16°C which is a tad low, but with the cheap eQ-3 I can set the eco and comfort settings and once set pushing one button swaps between them until a program change is reached, and boost button opens up TRV head to 80%, it also actually tells you if the valve sticks, or travel too much or too little, no putting spacers in like the MiHome Energenie.
But most of these systems you only learn what they can do after you have bought them, all top often you get "Follow the instructions on the app." which means no idea how it works until you have bought and installed it.
So the instructions for Hive seem great, the way it should integrate wall thermostat to TRV head, but so did Nest and MiHome Energenie until I tried it.
So other than MiHome Energenie and Nest which I now know, how do the other makes work, do they really integrate, or when it comes to real life are there problems? Specially using wall thermostat and TRV in same room, if my TRV fails to alter temperature in any room other than hall, it just means one room is wrong temperature, but if the hall TRV fails to follow set seclude, so it does not match the wall thermostat, then heating can get stuck on or off. As yet not happened but the TRV uses batteries, not sure what MiHome Energenie does when batteries discharge, the eQ-3 TRV head is designed to open once battery becomes depleted, MiHome Energenie don't tell you, should last 2 years, I change every year to make sure.
So what does Hive, EvoHome, or Tado TRV heads do when batteries become depleted?
It is now expected to have both TRV and Wall thermostat in the same room, but from the quote it is clear they have to be set to complement each other and not fight each other.MIHO069 Full User Guide said:TRV warmup time (16)To allow any TRVs to reach their own designated target temperature, the heating can be set to continue heating for abdefined time after it has reached the target temperature at the thermostat location. This TRV warm up time can be set from the settings section on either the web browser, or smartphone app.
