Heat Controller R68DD0014 -0.2" Pressure Switch

The Heat Controller R68DD0014 is a negative pressure switch designed for HVAC applications, calibrated to activate at -0.2 inches of water column (w.c.). This pressure-sensing safety device monitors air pressure differentials in heating and cooling systems to ensure proper operation and system safety.

Key Features:

• Calibrated set point of -0.2 inches water column for precise pressure monitoring
• Normally open (N.O.) or normally closed (N.C.) contact configuration for versatile installation
• Designed for use in furnaces, air handlers, and HVAC control systems
• Monitors vent pressure, draft pressure, or airflow to prevent unsafe operating conditions
• Factory-calibrated for reliable, consistent performance
• Compact design for easy installation in tight spaces

This pressure switch serves as a critical safety component that can shut down equipment if proper draft or airflow conditions are not maintained. Commonly used in combustion appliances to verify proper venting, or in air handlers to confirm adequate airflow before allowing system operation. Direct replacement for Heat Controller OEM equipment.
