Field Setting of Outdoor Unit
1. Connect the demand adapter X80A to X36A and X66A on the outdoor unit control PCB.
2. According to the desired demand, short-circuit between the terminals on the demand
2.2.2 Low Noise Operation by External Input
External input enables low noise operation by restricting outdoor fan rotation speed and
compressor operation frequency. (Use at night or other time when the load is small.)
1. Turn ON the DIP Switch (DS1-3) on the outdoor unit control PCB.
2. Short-circuit between the terminal blocks X801M and COM on the demand adapter. (Low
