A19PRC-1C Johnson Controls Temperature Control

Overview

The Johnson Controls A19PRC-1C is a single-stage mechanical temperature control designed primarily for heating and ventilation applications in demanding environmental conditions. It features a rugged thermoplastic enclosure that complies with NEMA 4X specifications, making it rain-tight and suitable for agricultural and industrial environments requiring NEC Article 547 compliance. The device utilizes a liquid-filled coiled air sensing element to accurately monitor and respond to temperature changes.

Features

• Rugged NEMA 4X raintight thermoplastic enclosure ideal for high-moisture agricultural and industrial settings.
• Coiled air sensing element provides efficient temperature responsiveness.
• O-ring sealed setpoint adjustment knob protects the internal mechanisms from dust and moisture.
• Exposed portions of the liquid-filled sensing element are plated and plastic-coated to resist damage in corrosive atmospheres.
• Heavy-duty Single Pole Double Throw (SPDT) switch action that opens or closes on temperature rise.
