6. Mode set by external input
6.1 Low -level sound priority mode (Local wiring)
By performing the following modication, operation noise of the outdoor unit can be reduced by about 3-4 dB.
The low noise mode will be activated when a commercially available timer or the contact input of an ON/OFF switch is added to
the CNDM connector (option) on the control board of the outdoor unit.
● The ability varies according to the outdoor temperature and conditions, etc.
Complete the circuit as shown when using the external input adapter (PAC-SC36NA-E). (Option)
SW7-1 (Outdoor unit control board): OFF
SW1 ON: Low noise mode
SW1 OFF: Normal operation

6.2 On demand control (Local wiring)
By performing the following modication, energy consumption can be reduced to 0–100% of the normal consumption.
The demand function will be activated when a commercially available timer or the contact input of an ON / OFF switch is added
to the CNDM connector (option) on the control board of the outdoor unit.
Complete the circuit as shown when using the external input adapter (PAC-SC36NA-E). (Option)
By setting SW7-1 on the control board of the outdoor unit, the energy consumption (compared to the normal consumption)
can be limited as shown below.
