Supco F7799 Control Board

The Supco F7799 Fan Control Board serves as a critical direct replacement for 1088977 (and HQ1088977A1), commonly found in HVAC systems manufactured by brands such as Tempstar, Heil, and Comfortmaker. Specifically engineered for condenser units, this board regulates fan speed based on ambient outdoor temperatures to maintain stable head pressures for system efficiency. This furnace control board supports high-amperage applications with an output low speed of 20A and a high speed of 10A at 240VAC. The compact, robust design ensures consistent performance in extreme environments with an operational range from -40°C up to 167°F. Professional technicians will appreciate the 24 VAC/DC input versatility and precise 80°F or 88°F temperature set points (determined by the tab configuration), designed to protect the compressor and optimize the refrigeration cycle across various heating and cooling maintenance requirements.

• Universal Compatibility: Serves as a direct aftermarket replacement for 1088977, facilitating rapid repairs on major condenser unit brands.
• Precision Thermal Regulation: Features a 1 to 2-second delay on make and specialized temperature differential set points to prevent short cycling.
• Industrial Durability: Rated for high-humidity environments (up to 95% condensing) to ensure reliable operation in outdoor enclosures.
• Enhanced Efficiency: Precisely manages HVAC ventilation speeds to reduce energy consumption and improve overall system lifespan.

• Is the F7799 compatible with both DC and AC circuits? Yes, this board accepts an input voltage of 24 VAC or DC ± 10%, making it versatile for different control wiring setups.
• What are the temperature set points for this board? With the tab intact, the set point is 80°F; removing the tab adjusts the set point to 88°F, allowing for onsite calibration.
• Can this be used for other brands besides Comfortmaker? As a high-quality HVACR part, it is a suitable replacement for numerous brands using the 1088977 model, including certain Heil and Tempstar units.
