(2) Remote ON/OFF 2 (Pulse Signal Input) [ Input Setting: Code (04) ]
This is an ON/OFF function from a remote place by using pulse signals. An example of a basic wiring
and time chart is shown below.

3P Connector
Signal to terminals 2 & 3 of CN3 (Operation)
Signal to terminals 1 & 2 of CN3 (Stop)
Control by Wired Controller
NOTE:
Operation priority is given to the remote
ON/OFF signal or wired controller
signal which is given last.
NOTES:
1. Picking up signal within 10 seconds after power supply is turned ON is not possible due to initialization
of the components.
Do not change the signal (ON/OFF) in this period.
2. Wired Controller is required for this function.
3. If multiple indoor units are connected to the same communication cable for wired controller, input the
signal to any of these indoor units.
4. When the communication cable is not used in the twin, triple and quad combinations for simultaneous
operation, input the signal to the main indoor unit.
