2-4-5 Start/Stop Control of Indoor Units
Each indoor unit (or group of indoor units) can be controlled individually by setting SW 1-9 and 1-10.
*1. Do not cut off power to the outdoor unit. Cutting off the power supply to the outdoor unit will cut off the power supply to the
crankcase heater and may cause the compressor to malfunction when the unit is put back into operation.
*2. Not applicable to units with a built-in drain pump or humidifier.
*3. Models with a built-in drain pump cannot be turned on/off by the plug individually. All the units in the same refrigerant cir-
cuits will be turned on or off by the plug.
*4. Requires that the dipswitch settings for all the units in the group be made.
*5. To control the external input to and output from the air conditioners with the PLC software for general equipment via the
AG-150A, GB-50ADA, or G(B)-50A, set SW1-9 and SW1-10 to ON. With these settings made, the power start-stop func-
tion becomes disabled. To use the auto recovery function after power failure while these settings are made, set SW1-5 to
ON.
