The zone valve to one of my buildings is constantly opening and closing. Within minutes. I checked the sensor on another building and it is working fine. I don't know if the valve is not getting a signal, maybe a wire is loose (although I have followed them and don't see evidence of this). Is my thermostat box messed up. The only way I could get the zone valve to stop was to cut the power wires. I can now hook them up - let it either open or close depending on whether building is too hot or too cold - then unhook the wires to leave valve in either open or closed position. What do I need to do? New zone valve? Maybe a new thermostat. I think the sensor is working fine.
