The circuit for A cycle generates 35V of the power supply voltage for the indoor unit 1¥ 2, and 12V and 5V for the drive of
electric expansion valve. Similarly . the circuit for B cycle generates 35V of the power supply voltage for the indoor unit 3 ¥ 4,
and 12V and 5V for the drive of B cycle electric expansion valve. The voltage specification of each output is in fig . 4-2 below.
