Description

Motormaster® V Low Ambient Control

The Motormaster® V control is a motor speed control device which adjusts condenser fan motor speed in response to varying discharge refrigerant pressure. A properly applied Motormaster V control extends the operating range of air-conditioning systems and permits operation at lower outdoor ambient temperatures.

To operate these units at very low ambient temperatures, Motormaster V controls must be added. Field-fabricated and installed wind baffles are also required for units in areas with prevailing winds of more than 5 mph and where temperatures drop below 32°F (0°C). The Motormaster V control permits operation of the unit to an ambient temperature of –20°F (–29°C). The control regulates the speed of one 3-phase fan motor that is compatible with the control. Replacement of fan motor on most units is not necessary since the control is compatible with the factory-installed fan motors. Field wiring of control is required.

This accessory kit will allow the Motormaster V Control to be used on heat pump units (using the single 3-phase outdoor fan motor). A second relay assembly is provided as part of the heat pump adapter kit to override the Motormaster V when in heat pump mode. The second relay must be installed by the technician. For cooling units, the second relay assembly is not needed.
