21 580F LEGEND C Contactor 580F Fig. 19 Motormaster I Wiring Details LEGEND C Contactor OFC Outdoor-Fan Contactor TRAN Transformer *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.
