MOTOR TYPES
The relationship between the voltage supplied to a motor and its operating speed is described by
a motor type. This type varies with the make and capacity of the motor. The various motors
available in the industry have been represented.
Select the appropriate type to ensure that the controller supplies the correct voltage to the stage
1 and 2 variable speed fan motors. The factory default selection is type number 10.
