[QUOTE="Doc Hudson, post: 473058, member: 1607"] Did the valves make this noise before you replaced the thermostats? It sounds to me like something is wired wrong. I would want to electrically isolate the valve and thermostat from each other to measure what voltages are appearing where and what direction they are coming from. i.e. Is it something from your Tado kit repeatedly energising and de-energising the valve, or does the valve give the same symptoms if you just manually trigger it with a temporary link to imitate the thermostat signals? I doubt this problem is going to be easily solved without someone actually doing some physical tests on your installation. Doc H. [/QUOTE]
