Description
The Johnson Controls A19ZBC-12 Temperature Control is a versatile controller that controls and preserves the temperatures of HVAC applications. It uses voltages of 120 VAC or 208/240 VAC; it can be installed and also connected to various types of HVAC equipment. The capillary length of 10 feet and the operating temperature that ranges from 0°F to 70°F provide versatile temperature sensing and control within different environmental conditions. Operated by an SPDT contact type, this control reacts to temperature fluctuations by distributing energy from heating or cooling machinery. This works by having its capillary tube and bulb be sensitive to the temperature of its surroundings.
