*1. When switching to Remote, control at Local remote controller will NOT be effective, but the "CENTRALLY CONTROLLED" is displayed.
*2. MA or ME remote controller is needed for this function.
*3. If using ON/OFF input function, Automatic-address-start-up can not be performed to start-up the system at commissioning.
*4. If CITY MULTI use GB-50A/AG-150A and PLC software to control the Indoor unit via its external input/output connectors, Dip Switch 1-9 and Dip Switch 1-10
should be set to ON.
In this case, the input/output connectors act as normal connectors, functions mentioned at Table 1-2 are no more available.
Details are available at the PLC software Instruction Manual.
Table 1-3. ON/OFF control to each Indoor unit (group) by using Dip Switch 9 and 10 (SW1-9, SW1-10) of the Indoor unit.
Function
Auto ON
Auto recovery
All OFF
*1. The Dip Switch setting should be carried out on every Indoor unit in the group.
*2. Outdoor unit's power supply should NOT be cut. Otherwise, power supply to case heater of the compressor would be cut too, which may cause damage to the
compressor.
*3. Above method can not be applied to the power ON/OFF of the drain pump and humidifier equipment.
*4. If CITY MULTI use GB-50A/AG-150A and PLC software to control the Indoor unit via its external input/output connectors, Dip Switch 1-9 and Dip Switch 1-10
should be set to ON.
In this case, the input/output connectors act as normal connectors, functions mentioned at Table 1-3 are no more available.

Restart of the CITY MULTI needs to be careful. When no power supply to the outdoor unit, no power supply to the compressor case heater too. The compressor
needed to be warmed up before running. When using above functions, power supply to the outdoor unit should be ensured.

Description
1 Control combining distant/local
2 Pulse ON/OFF
3 HA ON/OFF(JEMA)
4 Power ON/OFF
5 Automatic recover
*1. Pulse ON/OFF, power ON/OFF and automatic recover can only be used when the remote/local setting CN32 is set to local.
Therefore, always avoid this function when combining control.
Indoor group can be controlled ON/OFF by an ON/OFF switching or contact input to
the connector of the head Indoor in an Indoor group.
It can be interlocked with timer, door, window, or other equipment to "Force stopping"
Indoor group can be controlled ON/OFF by an external pulse signal input to the
connector of the head Indoor in an Indoor group.
Indoor group can be controlled ON/OFF by an ON/OFF switching or contact input to
the connector of every Indoor in an Indoor group.
Signal output from a head Indoor unit, presenting its Indoor group.
It can be used for monitoring or interlock with other equipment purpose and so on.
Signal output from every Indoor unit, for monitoring Error or Thermo-off (fan) state.
It can be used for monitoring or interlock with other equipment purpose and so on.
Operation on Indoor units
All indoor units will turn ON and automatically resume to its previous mode after 5 minutes from
power recovery.
Indoor unit recovers to its previous state (ON/OFF, mode) after 5 minutes from power recovery.
Forced stopping regardless of Indoor units' state.
