I have a Carrier multi-zone system (4 zones) and the Infinity controller. There are several people living in the house and they adjust the controller to suit themselves, not the whole household. I find in the manual how to lock-out the controller but on the main controller the temp can be adjusted and just found out the heat can be switched to air. I don't have a problem with them changing the temp in their zone but turning the heat off and air on is a problem. Talking to them doesn't have any affect....
Why doesn't lock-out lock it out????
Thanks..
