13.13.4.6 Sunlight Sensor Abnormality
Abnormality detection:
o When ECONAVI is ON, if the sunlight intensity value below minimum level continuously for 24 hours, the
sunlight sensor disconnection error counter will increase by 1 time. If the ECONAVI is OFF, the 24 hours
timer will be reset, but the sunlight sensor disconnection error counter will not be reset.
Error Code judgment
o When sunlight sensor disconnection error counter reached 15 times. H70 occurred.
o No TIMER indicator or ECONAVI indicator blink.
When error code happened, the unit is able to operate without sunlight sensor.
13.14 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).
