3. Outdoor application operation
Application Control Kit
(TCB-PCOS1E2)
(1) Peak-cut control
• Saves the power of the outdoor unit by the external peak-cut signal to suppress temporary peak power
dissipation.
• The power saving can be switched to three levels: 75%, 50%, and operation stop.
(2) Night operation
• Reduces the capacity of the air conditioner by the input signal from a commercially available timer (procured
locally) regardless of the outside air temperature or load to reduce operating noise.
• There are some noise levels for Night operation.
By setting DIP switches of Application Control Kit, the noise level in Night operation (Sound reduction) mode
can be selected.
1. Make sure of the color (green or black) of the DIP switches (SW01) on the P.C. board.
2. Referring to the table below, set the DIP switches for the desired noise level.
(3) Compressor output
• Turns on the no-voltage contact output while the compressor is operating.
