A19BAC-15C Johnson Controls Temperature Control

Overview

The Johnson Controls A19BAC-15C is a single-stage temperature control space thermostat designed for automatic heating or ventilation regulation in commercial, agricultural, and general-purpose applications. It features a heavy-duty electromechanical design housed in a dust-tight enclosure, utilizing a liquid-filled sensing element to deliver highly responsive and reliable operation that remains unaffected by barometric pressure or altitude variations.

Features

• Liquid-filled coiled bulb sensing element provides rapid response and uniform control
• Single-pole, double-throw (SPDT) snap-acting contacts enclosed for dust protection
• Factory-mounted external range adjustment knob for simple temperature setting updates
• Built-in adjustable cutout stop screw allowing installers to set fixed high or low system operation limits
• Rugged construction designed for surface mounting or attachment via wiring conduit

Specifications

• Temperature Range: 30 to 110 degrees Fahrenheit (-1 to 43 degrees Celsius)
• Differential: 3.5 +/- 2 degrees Fahrenheit fixed differential
• Contact Type: SPDT switching action
• Electrical Ratings: 16.0 Full Load Amps at 120 VAC; 9.2 Full Load Amps at 208 VAC; 8.0 Full Load Amps at 240 VAC
• Pilot Duty Rating: 125 VA
• Sensor Element: 1-3/8 inch x 2-1/4 inch coiled air bulb

Applications

• Ideal for agricultural structures requiring stable ambient conditions, including livestock barns, poultry houses, milk houses, and brooder houses
• Used in commercial heating, cooling, and ventilation applications to manage space temperatures
• Suitable for general-purpose environmental control, refrigeration equipment, and industrial spaces needing a durable, non-powered electromechanical thermostat
