this control board is specifically engineered for single-stage heating systems and manages the 24V signal to the gas valve following a verified flame signal

or "open circuit" fault codes on the control board that persist even after replacing sensors

this relay serves as a primary switching component for heavy-duty inductive loads

allowing technicians to take precise readings from a distance

Daikin-McQuay 113103601 Control R-407A this control board is specificallyThe 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,
