Daikin-McQuay 802005724 Tstat

The Daikin-McQuay 802005724 Tstat is a specialized low-limit control thermostat engineered for precise thermal management in commercial air handling systems and chillers. Operating with a 28-degree out and 38-degree in temperature differential, this HVAC freeze protection switch ensures mechanical safety by preventing coil freeze-up or evaporator damage during low-ambient conditions. Its fixed 55-degree max setpoint provides critical oversight in sequencing, making it an essential OEM replacement part for maintaining system integrity in McQuay and Daikin Applied equipment. Built for high-cycle reliability, the SPST or SPDT configuration facilitates seamless integration into existing safety control circuits and BAS monitoring systems. Field technicians prioritize this Daikin 802005724 for its consistent setpoint accuracy and rugged construction, ensuring the unit triggers protective lockouts or bypasses before structural damage occurs. This mechanical thermostat is verified for compatibility with specific modular air handlers where precision temperature thresholds are non-negotiable for operational uptime.

• Precise Thermal Callouts: Calibrated for a 28°F cutout and 38°F cut-in to prevent liquid floodback and coil icing.
• OEM Compatibility: Exact drop-in replacement for Daikin-McQuay 802005724 ensures electrical and mounting alignment.
• Reliable Fail-Safe: Hard-wired 55°F maximum limit prevents overheating or incorrect staging in sensitive environments.
• Industrial Durability: Tested for high-vibration applications found in roof-mounted and mechanical room equipment.

• What systems use the 802005724 thermostat? This component is typically found in Daikin-McQuay air handlers, chillers, and fan coil units requiring a low-limit safety cut-out.
• Can this be used as a primary temperature controller? No, this is a safety and limit control device designed to protect equipment, not to regulate occupied space temperatures.
• Is the differential adjustable? This specific model features factory-set thresholds (28-out/38-in) to meet manufacturer safety specifications.
