The problem I have is that my radiators would not get hot when turned thermostat up .but thermostat clicked when turned up,I have a 3 port control valve so I turned it from auto to manual then I got rads hot when I moved lever back to auto rads would not cool down so I had to switch off at control switch, don't know if it is motor on zone valve that is burnt out or the valve itself.can anybody help
