Industrial KSALA0601AAA MotorMaster Low Ambient Controller

The Motormaster KSALA0601AAA Low Ambient Controller is an OEM Carrier kit that modulates condenser fan motor speed to regulate the saturated condensing temperature in cooling mode, maintaining about 100°F ±10°F across outdoor temperatures as low as -20°F. Configured for 208/230V, 1-phase, 60 Hz operation, it includes a solid-state control board housed in an aluminum enclosure and a matched sensor assembly that mounts to the condenser coil return bend; both the control board and the sensor are replaceable independently. The enclosure measures roughly 9 inches deep by 8 inches wide by 5 inches high, and shipping weight is about 3.5 pounds; listings often note a California Prop 65 warning. As an official Carrier Motormaster Low Ambient Controller kit (KSALA0601AAA), it is designed for OEM installation on Carrier HVAC equipment and is distributed through authorized Carrier distributors.
