selected randomly) after power supply resumes.
This type of control is not applicable during ON/OFF Timer setting.
This control can be omitted by open the circuit of JP1 at indoor unit printed circuit board.

14.11 HA Terminal (HAJEM-A)
Enable digital connection from indoor unit to external devices.
Control
items:
1 Start/stop
input.
2 Start/stop signal output.
Condition
1 1-2 (Pulse input): Unit ON/OFF condition switching with a pulse signal.
(1 pulse signal: shortage status 200~300msec)
2 3-4 (Static output): 5V output during the unit ON. No output at OFF.
Example of wiring:
Note: The wire length from indoor unit to the external interface must be within 1.9 meters. The wire must be double
insulation type and a ferrite core to be added to reduce noise. Proposed core spec is J0KE00000147 with Heat
Shrinkage Tube.
The signal between indoor unit and the external interface must be isolated by photo-coupler of approval type
(e.g: Semko, VDE etc).
