Enviro-tec PC-03-0002 Switch

The Enviro-Tec PC-03-0002 is a precision-engineered pneumatic-electric (P/E) switch designed for VAV box control and HVAC sequencing. This SPDT pneumatic switch features versatile Normally Open (N/O) and Normally Closed (N/C) contacts, making it essential for interfacing pneumatic signals with electrical HVAC components. Built for reliability in commercial air handling units, the switch triggers electrical circuits based on specific pressure setpoints, ensuring accurate damper actuator operation and fan terminal unit management. Its robust construction minimizes signal drift, maintaining calibration in high-cycle environments. Whether you are replacing a legacy Enviro-Tec pressure switch or performing a system-wide retrofit, this component provides the exact differential pressure sensing required for maintaining ASHRAE-compliant airflow cycles. The compact design allows for easy mounting within existing control enclosures, facilitating rapid field installation for mechanical contractors and service technicians.

• Multi-Configuration Logic: Supports both N/O and N/C wiring for flexible system integration.
• Pneumatic Compatibility: Seamlessly interfaces with standard 3-15 psi pneumatic control signals.
• Durable SPDT Contacts: Engineered for high-frequency switching in terminal unit controllers.
• Field Reliability: Reduces troubleshooting time by providing consistent, repeatable setpoint activation.

What is the primary function of this P/E switch?
It converts a pneumatic pressure signal into an electrical contact closure or opening to control fans, heaters, or alarms within a VAV system.

Can this replace other PC-03 series switches?
Yes, the PC-03-0002 is a standard replacement for Enviro-Tec terminal units, provided the electrical ratings and pressure ranges match the original submittal data.

Does it require specific calibration during installation?
While factory-configured, technicians should verify the trip point using a calibrated pneumatic squeeze bulb to ensure alignment with the sequence of operations.
