• Integrated Defrost Sensor for Accurate Ice Detection:Equipped with a factory-calibrated defrost sensor, this control board accurately monitors the temperature of your outdoor coil to determine when a defrost cycle is needed. The sensor is pre-wired and securely connected, eliminating guesswork during installation. It ensures your heat pump runs efficiently all winter long
• Industrial-Grade Relays for Full System Control:This control board manages all critical functions of your heat pump with heavy-duty relays built to OEM specifications.These relays ensure smooth, reliable switching of high-current components, reducing wear on your system and preventing premature failures. The board is rated for 24VAC (18–30VAC) and 50/60 Hz, making it compatible with standard residential HVAC control systems
• Built to Survive Extreme Conditions – From Arctic Cold to Humid Summers:Designed for real-world HVAC environments, this control board operates flawlessly in temperatures from -40°F to 150°F (-40°C to 65°C) and humidity levels up to 95% (non-condensing). The conformal-coated PCB resists moisture, dust, and corrosion—common causes of electronic failure in outdoor units
