EXTERNAL INPUT/OUTPUT AND FUNCTION SETTING
5.4.1.1 Remote Control ON/OFF Function
This function provides a control to stop and start the system automatically from a remote place. Four
methods are available by using each signal from a building management system.
(1) Remote ON/OFF 1 (Level Signal Input) [ Input Setting: Code (03) ]
This is an ON/OFF function from a remote place by using level signals (ON/OFF). An example of
basic wiring and time chart is shown below.
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.
