Enviro-tec PE-09-1105 Limit Switch

The Enviro-tec PE-09-1105 is a precision-engineered auto limit switch designed for critical thermal protection in VAV terminals and fan coil units. This SPST high limit switch features a fixed temperature setting of 90°F to 105°F, ensuring the blower motor or heating element shuts down before exceeding safe operating temperatures. Built for low voltage HVAC controls, the PE-09-1105 utilizes a dependable bimetallic disc for snap-action response and automatic reset once temperatures drop below the established differential. When performing Enviro-tec parts replacement, this switch serves as a direct drop-in for HVAC safety limit applications, maintaining the sequence of operation and preventing overheating in ductwork. The compact design allows for rapid installation in tight control cabinets, while the factory-calibrated setpoints eliminate field adjustment errors, ensuring the HVAC terminal unit safety protocols remain intact for long-term commercial performance.

• Precise Thermal Protection: Maintains a strict 90-105°F operating range to protect system components from heat damage.
• Automatic Reset Function: Eliminates the need for manual intervention by restoring the circuit once safe temperatures are achieved.
• Direct OEM Compatibility: Engineered specifically for Enviro-tec VAV units, ensuring electrical and mechanical fit.
• Durable Bimetallic Construction: Provides long-cycle life and consistent switching reliability under varied thermal loads.

Is the PE-09-1105 a manual or automatic reset switch?
