EXTERNAL INPUT
ON/OFF of the "Low noise mode" and "Peak cut mode" functions can be specified by external
signal.
Low noise mode
z
On-site work like the following also reduces the operating sound of the outdoor unit from the
•
normal sound.
The air conditioner is set to the "Low noise mode" by applying the contact input of a commercial
timer or ON/OFF switch to a connector on the outdoor control PC board.
* Performance may drop depending on the outside air temperature condition, etc.

Wire (External input)) : Red / White / Black
1) Power supply
●Voltage (Chart sign=Vcc) : DC 5V to 24V
●The current capacity : About 100mA
2) Switch (Chart sign=SW)
● Toggle switch or Rocker switch, etc : Switch which maintains the
states.
● Prepare switches which are enough capable for DC 10mA
current or more
3) Resistance (Chart sign=R)
●Adjust the resistance for current to about DC 10mA
(Example)
●In case of Vcc=DC 5V : Rated resistance value 470Ω 1/4W
●In case of Vcc=DC 12V : Rated resistance value 1kΩ 1/4W
●In case of Vcc=DC 24V : Rated resistance value 2.2kΩ 1/4W
