L4064B2236 Fan And Limit Control Switch, 120V

The Honeywell L4064B2236 is a fan and limit control switch designed for forced air heating systems. This essential component regulates when the furnace fan turns on and off based on plenum temperature, and sets a high limit to prevent the system from overheating. It is commonly used in residential and light commercial heating applications where automatic temperature control and safety are priorities.

This control maintains consistent comfort by automatically adjusting fan operation in response to temperature changes. The device prevents overheating damage to the furnace and connected ductwork while ensuring the fan runs only when needed for efficient heating.

Features and Benefits

• Dual Temperature Control: Fan temperature range of 50 to 200°F and limit temperature range of 100 to 250°F provide flexible operation across different heating demands.
• Automatic Fan Operation: Turns the fan on and off automatically based on plenum temperature, reducing manual adjustment needs.
• High Limit Safety: High limit setting prevents overheating and protects the heating system from damage due to excessive temperatures.
• Manual and Automatic Settings: Switch between manual and automatic fan control modes depending on your specific heating requirements.
• 120V Compatibility: Standard 120 volt operation simplifies installation and reduces the need for additional electrical components.
