In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have a three zone hydronic infloor system heated by a munchkin boiler. Zones are controlled by two wirsbo actuators and one uponer actuator. One of my zones turned on/opened earlier today and has not shut off despite having satisfied the thermostat hours ago. Thermostat is set at 50 (its a workshop) and room is close to 70 degrees. pump is running constantly. Boiler appears to be turning off and on as it should (dependant upon return temperature). How should I troubleshoot this? Do I likely need a new actuator? Is there something I can do manually for the short term to shut down the heat in that room?
OK so this is what I did. I disconnected every wire that was associated with that actuator. First I disconnected the wires (one white one yellow) from the thremostat communicating with that actuator - the actuator stayed open/pump on. So I discoinnected the other yellow wire and the two red wires associated with that actuator. That worked for now - the pump is off. That actuator is still open which I believe means that that room will get heat when another zone calls - that is a good thing. I have basicly made it a two zone system yes? Until I can get a new actuator. Any feedback appreciated.
