Hi, My vFlow valve on my TZ climatemaster is not fully closing when the unit is off and the valve position is indicating 0% on the thermostat. This means I am pumping some water through my open loop 24/7. I have tried adjusting the valve configuration voltage in thermostat installer settings, but all selections seem to still result in an partially open valve. I would really appreciate any suggestions on how to further troubleshoot. Thanks!
