Lennox 60M10 Honeywell W7212A1033 Enthalpy Control Module

The Lennox 60M10 is a Honeywell W7212A1033 Economizer Logic Module designed to optimize energy efficiency and indoor air quality in commercial HVAC systems. This advanced control module intelligently manages outdoor and return air dampers to provide free cooling when outdoor conditions are favorable, reducing energy consumption and operating costs.

Key Features:

• Enthalpy-based economizer control for precise air quality management
• Operates on standard 24 VAC power supply at 50/60 Hz
• Wide operational temperature range from -40°F to 149°F (-40°C to 65°C)
• Compatible with C7400 Solid State Enthalpy Sensors or C7660 Dry Bulb Temperature Sensors
• LED indicators for free cooling status, DCV mode, and exhaust fan operation
• Proportional damper control for optimal ventilation and free cooling
• Built-in adjustable setpoints (A, B, C, D) for customized control
• Contact rating: 1.5A at 30 VAC running, 3.5A at 30 VAC inrush
• Compact design: 4-1/8" H x 4-3/8" W x 1-5/8" D

This economizer control module measures both temperature and humidity (enthalpy) of incoming outdoor air and compares it to preset values or return air conditions. When outdoor air conditions are favorable, the module opens dampers to use free cooling instead of mechanical cooling, significantly reducing energy costs. The Lennox 60M10 defaults to free cooling mode on startup with closed position during freeze protection, ensuring safe and efficient operation year-round.
