System and Method for Defrost of an HVAC System
First Claim
1. A method of controlling a heating, ventilation, and air conditioning (HVAC) system, comprising:
- executing a field defrost algorithm;
monitoring whether a condition meets a criteria;
executing a certification defrost algorithm in parallel with the field defrost algorithm in response to the condition meeting the criteria;
performing a certification defrost cycle if demanded by the certification defrost algorithm; and
performing a field defrost cycle if demanded by the field defrost algorithm.

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.
