You have proved the valve is/was bad. The new ccu may not be as good as the one in there now. Fix/replace the valve and go from there.

Hey Paul,
I have replaced the monovalve twice. This last time there was nothing with the valve but at $15 for the new valve I figured it was worth a shot. It did not fix the problem. Now with the modified valve in I have full heat, I believe the CCU is bad, tellinig the monovalve to close when it shouldnt. New CCu should be here by weeks end so I will let yall know. In the meantime I am enjoying full heat!!
