Hi Harry, I also have a similar problem. I have just upgraded my heating controls to the wired VRC700 (installed in boiler front panel) and some Ambisense TRV's. I get up early in the morning for work and some of the radiators are hot, way above the setback temp. I'm interested to see a solution...

no probs :D

Hi, please excuse me if these are simple questions? I have just installed a Vaillant VRC430 (in boiler) and VR81 into Ecotec plus 831 combi but I'm not sure of some of parameters? How do I know which curve to set? On setup page A5, it states set parameter value 50c. Is this only to test...
