Abstract
A system and a method are provided for monitoring a condition and selectively executing a certification defrost algorithm for a heating, ventilation, and air conditioning (HVAC) system in response to the status of the monitored condition. A system and a method are provided for selectively operating a certification defrost algorithm in parallel to a field defrost algorithm. A system and a method are also provided for causing a controller to execute a first algorithm and for causing the controller to selectively execute a second algorithm while also executing the first algorithm where each of the first algorithm and the second algorithm are configured to selectively cause the HVAC system to operate in a defrost mode.
