I have scoured Google but I cannot find a simple solution!
My handicapped daughter's room needs accurate temperature control (+- 1C) .
Because of the radiator position TRV's (even with capillary remote sensors) are out.
What I think I need is an electric radiator control valve with a remote thermostat (not necessarily wireless).
When the thermostat is too cold the valve opens slowly to try to prevent overshoot.
When the temperature is correct the valve 'sticks'.
When the thermostat is too hot the valve closes slowly to try to prevent undershoot. (When I was a plant engineer many years ago this was called differential control, I think).
Can anyone suggest a supplier of such an integrated valve and thermostat system, or maybe suggest an alternative?
