Lennox 77W94 Actuator Motor

The Lennox 77W94 Actuator Motor is an essential OEM component designed for high-precision damper control in Lennox commercial and residential systems. Operating on a versatile 24VAC/VDC power supply, this 5VA motor facilitates exact proportional or two-position control of HVAC zone dampers and supply air bypass systems. As a direct replacement for the legacy 102692-01 part number, the 77W94 provides the necessary torque and reliability required for the L Connection Network zoning applications. Its robust construction ensures consistent airflow regulation, preventing the static pressure imbalances often found in modern multi-zone ductwork. For a successful field installation, technicians should verify the 50/60 Hz frequency compatibility and ensure proper 2VDC to 10VDC signal calibration to achieve full 90-degree rotation. This replacement actuator motor is engineered to maintain system efficiency by eliminating air leakage and ensuring optimal thermal distribution across all designated zones.

• Broad Compatibility: Engineered specifically for Lennox HVAC systems, ensuring seamless integration with existing damper assemblies and L Connection networks.
• Dual Power Input: Operates efficiently on both 24VAC and 24VDC, providing flexibility for various control circuit configurations.
• Enhanced Zoning Accuracy: Delivers precise airflow regulation to improve temperature consistency and reduce overall energy consumption.
• Industrial Grade Durability: Built to withstand demanding duty cycles in commercial air handlers and bypass duct environments.

What are the wiring requirements for the 77W94?
This actuator requires a 24V Class 2 transformer. Technicians must maintain strict polarity across multiple actuators to prevent erratic operation or control board failure.

Can this motor replace the 102692-01?
Yes, the 77W94 is the official OEM replacement for part number 102692-01 and is fully compatible with the same mounting brackets and shafts.

Does it support both zone and bypass dampers?
Correct. This actuator is designed for use in both zone damper applications and supply air bypass dampers within Lennox zoning architecture.
