Description
Honeywell T4031A1073 Refrigeration Temperature Controller Overview
The Honeywell T4031A1073 is a reliable, line-voltage refrigeration temperature controller engineered for precise temperature management in commercial and industrial refrigeration applications. Designed to operate on 120/240Vac power, this controller provides dependable switching performance across a wide temperature range, making it an ideal choice for walk-in coolers, refrigerated display cases, and other low-temperature environments.
Key Features
- Operating Voltage: 120/240Vac for broad compatibility with standard line-voltage systems
- Temperature Setting Range: -30°F to +50°F for versatile refrigeration control
- Maximum Operating Temperature: 125°F
- Differential Temperature: 3.5°F for consistent, stable temperature cycling
- Switch Type: 1 SPDT (Single-Pole, Double-Throw) for flexible circuit control
- Sensing Bulb: 3/8″ x 3″ copper bulb for accurate, responsive temperature sensing
- Capillary Length: 8 feet for flexible remote sensing installation
Application & Benefits
The T4031A1073 is purpose-built for refrigeration temperature control where reliable, repeatable switching is essential. The copper sensing bulb and extended 8-foot capillary allow the controller to be mounted away from the sensing point, providing installation flexibility in tight or complex refrigeration equipment layouts. The SPDT switch configuration supports both normally open and normally closed circuit arrangements, enabling use in a variety of control schemes including compressor cycling, fan control, and alarm circuits.
