Abstract:
A controller for heating, ventilation, or air conditioning (HVAC) equipment includes a communications interface configured to communicate with first HVAC equipment and second HVAC equipment and a processing circuit communicably coupled to the communications interface. The processing circuit is configured to detect a staging event for the first HVAC equipment occurring at a first time, obtain a delay time based on an estimated amount of time required to reach steady state after the staging event for the first HVAC equipment occurs at the first time, determine whether the delay time has elapsed since the staging event for the first HVAC equipment has occurred, and prevent the second HVAC equipment from staging in response to a determination that the delay time has not elapsed since the staging event for the first HVAC equipment has occurred.
