Zone monitoring systems and methods for a zoning system

The present disclosure relates to a control system for a heating, ventilation, and/or air conditioning (HVAC) system. The control system includes a user interface configured to receive a first input indicative of a first expected operating range of a first parameter in a first zone and to receive a second input indicative of a second expected operating range of a second parameter in a second zone. A first set point for the first parameter is within the first expected operating range and a second set point for the second parameter is within the second expected operating range. The control system includes a controller configured to manage operation of the HVAC system and to provide a first alert in response to the first parameter being outside of the first expected operating range and a second alert in response to the second parameter being outside of the second expected operating range.
