Daikin-McQuay 060015801 Control

The Daikin-McQuay 060015801 is a high-precision PC7 Pressure Control switch designed for critical airflow monitoring and regulation in commercial HVAC systems. This SPDT pressure control switch is engineered to operate within a specific range of .03" to 1.4" WC, making it an essential component for air flow proving and supply fan pressure sensing. Operating at 277V, this switch ensures that the system maintains optimal static pressure, preventing equipment malfunction by providing a reliable signal to the control board that the fan is operational.

For technicians servicing McQuay rooftops or Daikin air handlers, the 060015801 pressure switch is the standard for detecting airflow faults. When integrated into the supply fan section, it monitors positive static pressure to prove airflow before allowing the ignition sequence or cooling stages to proceed. Its Single Pole Double Throw (SPDT) configuration allows for versatile wiring into safety circuits, ensuring that if airflow drops below the setpoint, the circuit opens to protect the compressor and heat exchanger from low-airflow conditions. This genuine OEM part is a direct Johnson Controls P32AF-13 equivalent, built to maintain the tight tolerances required by high-efficiency Daikin equipment.

• Precise Pressure Sensing: Monitors a narrow static pressure range from .03" to 1.4" WC for accurate fan proving.
• System Protection: Safely shuts down heating or cooling cycles if airflow failure is detected, preventing coil freeze-ups or limit trips.
• High-Voltage Compatibility: Rated for 277V applications, common in industrial and commercial HVAC electrical cabinets.
• OEM Reliablity: Designed specifically for Daikin-McQuay air handlers and rooftop units ensuring perfect physical and electrical fit.

What does the PC7 fault code indicate on a McQuay system?
A PC7 alarm typically indicates an airflow fault. This happens when the Daikin 060015801 switch fails to close when the fan starts or fails to open when the fan stops, suggesting either a mechanical switch failure or an actual lack of static pressure in the ductwork.

Can this switch be used for high-limit static pressure applications?
The 060015801 is specifically calibrated for low-pressure sensing (up to 1.4" WC). For high-limit applications exceeding this range, a different differential pressure switch should be selected to match the specific safety requirements of the system.

How do I wire the SPDT contacts for a fan proving circuit?
Technicians should reference the unit's schematic, but typically the Normally Open (NO) contacts are used so that the circuit closes only when the PC7 pressure control senses adequate air pressure from the supply fan.
