I've noticed that the KE100 TRV will often be in heating mode but the valve remains closed. Appears to happen mainly when the current temperature gets close to the target temperature. Problem is I have the TRVs set up to control my boiler, this issue is causing the boiler to fire up for no reason.
I have 6 TRVs installed around the house and they all have this issue. I have tried calibrating them multiple times but nothing seems to resolve this

@Wayne-TP  are you able to investigate this please? To me, if the valve is closed the TRV should stop calling for heat. 
 

Thanks.
