*The Motormaster II head pressure controller is equipped with an alternate operating mode. When

this mode is selected, the controller shifts the fan cycle sequence to effectively raise the average
condensing temperature approximately 20 F higher than the standard operating mode. In this
alternate mode, the outdoor fan begins cycling at higher outdoor ambient temperatures. This
mode should only be used if the evaporator coil shows signs of frosting at low outdoor ambient
temperatures.

To select the alternate operating mode, move the jumper wire on the Motormaster II control board
from reset T1 to reset T2.

NOTE: Motormaster® II transformer is wired for 460-v supply; it must be rewired for 208/230-v
application. Be sure to insulate unused tap. Refer to color code.
