Antunes Controls 8562140020 Control

The Antunes Controls 8562140020 is a high-precision digital freezestat designed to protect HVAC coils from freezing conditions. Operating on a 24Vac power supply, this SPDT control features a 30-75 degrees F temperature range and includes a 20-foot capillary sensor for extensive coverage across the coil face. This unit serves as the direct replacement for 8562120010, offering improved reliability for low temperature cutout applications. Technicians can utilize the 1-10 minute adjustable timing delay to prevent nuisance tripping during defrost cycles or transient temperature fluctuations. The digital interface ensures accurate setpoint management, making it a critical component for commercial air handling units and rooftop unit freeze protection. Built for field durability, the Antunes 8562140020 provides essential HVAC freeze protection logic to maintain system integrity in cold climates.

• Universal Compatibility: Serves as the official 8562140020 replacement for 8562120010, ensuring seamless mechanical and electrical retrofitting.
• Enhanced Sensitivity: The 20-foot sensor lead allows for comprehensive monitoring of large evaporator coils to detect localized cold spots.
• Adjustable Time Delay: Integrated 1-10 minute timing knob allows contractors to fine-tune the system response and avoid short-cycling.
• Precise Control: Range of 30 to 75 degrees Fahrenheit provides flexibility for various refrigeration and comfort cooling setpoints.

What is the difference between the 8562140020 and the 8562120010?
The 8562140020 is the current production model and the manufacturer-specified direct replacement for the obsolete 8562120010, featuring the same electrical footprint and 24Vac requirements.

How do I wire this freezestat into a safety circuit?
This is an SPDT (Single Pole Double Throw) control. For standard freeze protection, the "Normally Closed" (NC) contacts are typically wired in series with the compressor contactor or fan relay circuit to break the 24V signal upon a temperature drop below the setpoint.

Can the sensor length be shortened?
No, the 20' capillary sensor should not be cut or kinked. Excess tubing should be carefully coiled and secured away from moving parts to maintain calibration accuracy.
