Product Features & Fitment

This control box safely manages the electrical distribution required to shift the rooftop unit between cooling modes and mechanical heat pump cycles. It includes a dedicated freeze sensor that monitors coil temperatures to prevent the system from icing over during low-ambient operations. The 9530A751 is specifically calibrated for Coleman-Mach HP2 Series Heat Pumps and Mach 8 Ultra-Low Profile units, and also supports the addition of an optional backup electric heat strip for extreme cold.
