摘要： Systems and methods utilized to create and perform an alert system in a heating, ventilation, and air conditioner (HVAC) system. One implementation includes a visual alert system to alert of a fault in the HVAC system. The system includes one or more LED lights indicating the fault and disposed on an exterior surface of a housing of the HVAC system. The system includes a programmable logic relay (PLR) having one or more relay outputs configured to activate, based on a type of the fault and according to fault/error codes, an alert notification. The alert system can operate without another device having a display for input and output, the other device displaying one or more parameters of the HVAC system. The system includes at least one of a high pressure switch, a low pressure switch, a differential air pressure switch, or an access panel switch.
