Antunes Controls 804112104 Pressure Switch

The Antunes Controls 804112104, specifically the Model RHLGP-A, is a dual-function high and low gas pressure switch engineered for precision monitoring in commercial burners, boilers, and HVACR systems. This 2-SPDT gas pressure switch features an automatic reset mechanism, ensuring continuous operation by cycling the electrical control circuit once gas pressures return to safe operating parameters. Designed for rugged environments, it monitors a high gas pressure range of 2" to 16" W.C. and a low gas pressure range of 2" to 14" W.C. simultaneously. Technical connectivity is handled via a 3/8" NPT high pressure connection, a 1/8" NPT low pressure connection, and a 1/8" NPT vent. This industrial gas pressure controller is housed in durable die-cast aluminum and must be mounted horizontally. By integrating this HVAC safety limit switch, contractors can ensure reliable fuel gas pressure monitoring and prevent equipment damage caused by pressure fluctuations outside specified setpoints.

• Dual-Range Monitoring: Consolidates high (2-16" W.C.) and low (2-14" W.C.) pressure sensing into a single, compact unit to save manifold space.
• Automatic Reset Logic: Eliminates the need for manual intervention after temporary pressure dips or surges, optimizing system uptime for commercial gas burners.
• Flexible Mounting: The rugged aluminum housing supports horizontal mounting without the need for high-precision leveling, simplifying field installation.
• Reliable SPDT Switching: Features 2-SPDT switches for versatile wiring into safety interlock strings and control logic circuits.
• Standard NPT Ports: Includes 3/8" High, 1/8" Low, and 1/8" Vent NPT connections for seamless integration with existing gas lines.

How do I adjust the setpoints on the RHLGP-A?
Scale indicators are located on the front of the unit and can be adjusted using the internal setpoint screws to match the specific inches of water column requirements of your appliance.

What is the maximum surge pressure for this switch?
The Antunes 804112104 is rated for a maximum surge pressure of 10 PSI and is suitable for ambient temperatures ranging from -40°F to 140°F.

Does this switch require a specific mounting orientation?
Yes, for accurate calibration and reliable operation, the switch must be mounted in a horizontal position with the inlet stem pointing down.
