Honeywell Home L4064B2236 Fan Limit Controller 8 Insert Furnace Safety Switch

Advanced Temperature Control System with Adjustable Fan & Limit Settings

Engineered for precision and durability, this fan and limit control unit ensures optimal thermal management for industrial or commercial applications. With an 8-inch insertion limit stop, it provides reliable protection against overheating by activating cooling fans at 200°F and deactivating them once temperatures drop to 125°F, maintaining consistent performance even under heavy loads.

Designed for seamless integration into existing systems, this unit offers three wiring terminal options—push-in receptacles for stripped wires and female connectors compatible with 1/4-inch male flag terminals—simplifying installation for technicians of all skill levels. The L4064B, L4064W, and L4064R models feature a manual fan override switch, allowing continuous operation of cooling mechanisms during critical maintenance or troubleshooting scenarios when automated control isn’t sufficient.

For added flexibility, field-adjustable fan speed and high-limit thresholds let you tailor performance to specific environments without requiring factory modifications. Mounting adapters included with TRADELINE models ensure secure placement while strain relief bushings safeguard wiring from physical stress or damage caused by vibration or movement in demanding workspaces.

This compact yet robust solution combines user-centric design with industrial-grade reliability:
– Precise temperature regulation (Fan On at 200°F / Fan Off at 125°F)
– Manual override capability for uninterrupted airflow management
– Tool-free installation via push-in terminals and flag connectors
– Adjustable settings adaptable to diverse operational needs
– Durable construction with protective strain relief components

Whether you’re optimizing HVAC systems or managing equipment cooling in manufacturing settings, this unit delivers efficient thermal control while reducing downtime through its intuitive setup and fail-safe design features.
