Daikin-McQuay 018482800 Stat

Ensure reliable temperature regulation in commercial and industrial HVAC applications with the Daikin-McQuay 018482800 unit-mounted thermostat. This heating/cooling auto changeover thermostat is a critical field-replacement component designed for seamless integration with Daikin and McQuay equipment, including PTAC units and fan coils. Operating on a 24VAC power supply, it features a technical control range of 45-99°F (7-37°C), providing precise temperature control for office spaces, warehouses, and retail environments.

Built for durability and ease of maintenance, this unit-mounted HVAC control eliminates the need for complex wall-mounted subbases in compatible systems. The mechanical auto changeover switch utilizes a 5/8" tube mounting profile, effectively replacing legacy part numbers 032327900, 184828A-00, and 323279B-00. As an OEM replacement part, it maintains system integrity by ensuring correct low-voltage thermostat wiring and streamlined interface performance, reducing the overall equipment footprint while maximizing thermal efficiency in the field.

• Efficient Auto Changeover: Automatically switches between heating and cooling modes based on ambient demand to maintain consistent setpoints.
• Direct Unit Mounting: Simplifies installation for technicians by mounting directly to the cabinet, reducing external wiring runs.
• Wide Compatibility: Serves as a direct replacement for various Daikin and McQuay legacy thermostats and Klixon/Therm-O-Disc 14TC33 models.
• Compact Industrial Design: Measures 4.5" x 2.5" x 1.5", making it ideal for tight mechanical compartments in commercial air handlers.

Is this thermostat compatible with 120V or 240V systems?
No, this component is rated strictly for 24VAC applications. Applying line voltage will cause immediate failure of the internal circuitry.

Does this unit replace the older 032327900 part number?
Yes, the 018482800 is the designated OEM replacement for the 032327900 and 18482800 series stats commonly found in older McQuay units.

Can this be used for a heat pump with auxiliary heat?
This specific model is designed for standard heating/cooling auto changeover. Verify your specific wiring diagram (R, C, Y, W terminals) to ensure it matches your equipment's staging requirements.
