59W22 - Lennox 100847-09, Limit Control, 140 Deg F, SPST, Open Switch Face

The Lennox 100847-09 Limit Control is a critical component designed to ensure the safe and efficient operation of heating systems. This device plays a crucial role in monitoring and controlling temperature levels, preventing overheating and potential damage. Below is a detailed description of the Lennox 100847-09 Limit Control, presented using HTML

Key Features:

• Temperature Control: The Lennox 100847-09 Limit Control is specifically designed to control and limit the temperature within a heating system. It operates as a safety measure to prevent excessive temperatures that could lead to equipment damage or safety hazards.
• Temperature Rating: This limit control is rated for a temperature of 140 degrees Fahrenheit (°F). When the temperature in the system reaches or exceeds this limit, the control will take action to safeguard the equipment and the surrounding environment.
• SPST Configuration: The limit control is configured as a Single-Pole, Single-Throw (SPST) switch. It has a normally closed (NC) contact that opens when the temperature exceeds the set limit. This action interrupts the electrical circuit to prevent further heating.
• Open Switch Face: The Lennox 100847-09 Limit Control is designed with an open switch face, allowing for easy access and adjustment. Technicians can set or reset the temperature limit as needed during installation or maintenance.
• Durable Construction: This limit control is constructed with durable materials to withstand the conditions and demands of heating systems. Its robust design ensures long-term reliability and performance.
• Compatibility: The Lennox 100847-09 Limit Control is designed to be compatible with Lennox heating equipment and systems. It is engineered to meet the specific requirements of Lennox heating applications.

Applications:

The Lennox 100847-09 Limit Control is an essential component in heating systems, particularly those used in residential and commercial HVAC (Heating, Ventilation, and Air Conditioning) applications. Its primary applications include:

• Furnaces: This limit control is commonly used in gas and oil furnaces to monitor and limit the temperature of the combustion chamber. It prevents overheating, which can lead to equipment damage or even safety hazards like fires.
• Boilers: In hydronic heating systems, such as boilers, the limit control ensures that water temperature remains within safe and efficient operating limits. It prevents excessive heating that could result in boiler failure.
• Unit Heaters: Unit heaters used in commercial and industrial spaces rely on limit controls to maintain safe temperatures within the heating units. These controls are crucial for preventing overheating and maintaining indoor comfort.
• Heat Pumps: Some heat pump systems use limit controls to monitor the temperature of heating elements or coils. They help regulate the heat pump's operation and prevent overheating.
