I have Caleffi radiant manifolds with their twistflow actuators. Some zones are getting a lot of heat while others are not getting heat. A likely explanation is that the valve is stuck open or closed, so it's not responsive to the thermostat in either direction.
From what I've read, I need to gently whack a pin that is connected to the internal plunger and then put some WD40 on it. But I can't find any documentation about how to access that pin on the Caleffi actuators and I"m reluctant to start unscrewing things without knowing what's under pressure.
Any tips?
