Hi there,

A friend of mine has an issue with 3 HR92's on 3 radiators where even if there is no demand and the HR92 is in sync with the evotouch and has a "0" position, the radiator continues to heat and should not.
It means the small pin is not completely pushed on the radiator TVR and lets hot water to flow ...

I have here a picture of this TVR but we are nit sure what type it is, so what adaptation to use :
