Daikin-McQuay 113103601 Control

The Daikin-McQuay 113103601 Outdoor Enthalpy Control is a critical component for optimizing economizer operations in commercial HVAC systems. This sensor monitors both outdoor air temperature and humidity to determine the total heat content (enthalpy) of the ambient air, ensuring the system only utilizes free cooling when conditions are within the specified enthalpy setpoint. Engineered for integration with Daikin Applied and McQuay rooftop units, this control prevents high-latent-load air from entering the building, protecting indoor air quality and reducing mechanical cooling load. Designed for durability in rooftop environments, the 113103601 enthalpy sensor provides precise analog or digital input to the main unit controller, allowing for seamless transition between economizer mode and mechanical refrigeration. As a direct OEM replacement part, it ensures proper fitment and restores the air-side economizer to factory efficiency levels, making it a vital commercial HVAC control for contractors maintaining energy-efficient building operations.

Key Technical Benefits

• Optimized Economizer Logic: Accurately measures outdoor air energy levels to maximize free cooling cycles.
• Seamless System Integration: Designed specifically for Daikin-McQuay rooftop unit compatibility, ensuring plug-and-play installation into existing control strings.
• Improved Energy Efficiency: Reduces compressor wear and tear by leveraging favorable outdoor conditions for temperature and humidity management.
• Industrial-Grade Construction: Built to withstand outdoor exposure and maintain calibration accuracy over a wide range of ambient conditions.
• Enhanced Latent Load Management: Prevents the intake of high-humidity air, maintaining superior building comfort levels compared to dry-bulb only sensors.

Common Technical Questions

Can I use the 113103601 as a dry-bulb only sensor?
While it measures temperature, this control is specifically designed for enthalpy logic to account for humidity. Using it strictly for dry-bulb sensing bypasses the latent heat protection it offers.

Which McQuay series is this control compatible with?
The Daikin 113103601 is widely used across various McQuay Maverick and Rebel series rooftop units; verify your specific wiring diagram for enthalpy input compatibility.

How do I verify if the sensor is functioning correctly during a PM?
Check the DC voltage output or resistance against the manufacturer’s enthalpy curve based on current outdoor ambient conditions to ensure the controller is reading the correct atmospheric data.
