I currently have a home heated with forced air with 3 zones and a honeywell mini zone controller. In times when it is extremely cold, my furnace has a hard time satisfying all 3 zones at once. The 3rd zone was an add on for a basement and with all 3 zones going the system has poor airflow. As a work around, I have been turning off one zone until the other zones are satisfied but I am hoping this is only short term. I would like to only have 2 zones on at once and then the 3rd zone can come on after one of other zones is satisfied. Does anyone know of a way to prioritize the zones or another possible way to correct this? BTW, this is my first time posting so please bare with me. Thanks!
