If it still doesn't work it might be because it can't calibrate the valve position when the valve wheel is not attached - it will try to wind the valve closed (CYCLE mode) but there is nothing to limit the rotation when it's not attached to the valve wheel - so the calibrate process will fail. I'm not sure if that will cause it to be unable to call for heat but if you want to be really certain, unscrew the white and black base off your radiator as well and fit it to the HR92 then close the latch and wait for CYCLE to finish.
Now it will most definitely be able to calibrate and will be able to call for heat. Now you can walk with it further into your house and adjust the manual override wheel on the top to see if it calls for heat!
The best most conclusive way to do this is set all of your other zones to a 5 degree override and hot water off (if applicable) and give that a few minutes to take effect so that there is no other demand and the boiler relay is off, then alternatively turn the HR92 you are carrying right down to 5 and right up to 30. Remember it takes up to 30 seconds for the motor to turn the valve head from one extreme to the other, and it waits until after it finishes turning before it sends a new wireless heat demand.
So turn the temperature to one extreme and wait for the motor to stop turning before deciding whether it worked or not. You should be able to bring the boiler relay on by turning it right up and off by turning it right down. If that works when you are in the house but not when you are in the conservatory it must be a signal issue! If it still doesn't work when you're near the Evotouch then there is some sort of binding issue or possibly even a hardware fault.
In that case I would try a reboot of the HR92 first and then the controller if still not working. I have occasionally had to reboot an HR92 by removing the batteries due to odd behaviour.
