• The figure at left only shows the transmission
cable connections. Power supply lines are
omitted.

of the power supply units. Provide a ground
point for the indoor-outdoor transmission cable
for each outdoor unit.
• Make sure that the centralized control switch
(SW2-1, or SW5-1 on some models) on the
outdoor unit connected to the M-NET
transmission cable is set to ON.
(Refer to the outdoor unit Installation Manual for
detailed information about dip switch settings.)
• When both Air To Water (PWFY) and air-
conditioning units are connected to the outdoor
unit of Y series, the functions of Setback,
System-Changeover, and Operation Mode
