A19ABA-40C Johnson Controls Temperature Control

Overview

The Johnson Controls A19ABA-40C is a single-stage mechanical remote bulb temperature control designed for a wide range of heating, cooling, and refrigeration applications. It incorporates an environmentally friendly liquid-filled sensing element and capillary to provide reliable, line-voltage switching based on temperature change.

Features

• Environmentally friendly liquid-filled sensing element
• Wide temperature ranges with a constant adjustable differential across the entire range
• Compact NEMA 1 enclosure with a screwdriver slot range adjuster
• Repeat accuracy that remains unaffected by cross-ambient conditions or barometric pressure variations
• Concealed differential adjustment to discourage unauthorized tampering
