A refrigerant monitor and alarm includes a sensor positioned to detect the level of liquid state refrigerant in the system and provide an electrical output signal therefrom, a digital display for displaying the refrigerant level, a circuit coupling the digital display to the sensor for actuating the digital display, and a heat reclaim system lockout circuit coupled to the sensor. In a preferred embodiment, the level display is a bar-graph LED-type display incorporated on a control panel also including a refrigerant level alarm and other parameter alarms.
