Adjacent Unit Setting Mode

When two indoor units are set adjacently, sometimes, both indoor units may receive signals from the wireless remote controller simultaneously. To ensure both indoor units operate properly, the IR Receiver Kit of one of them may be set at the mode [adjacent unit setting]. For example, for two indoor units A and B shown in the right figure, set B at the mode [adjacent unit setting].

a. Method to set the adjacent unit setting mode

1. Set the IR Receiver Kit
   Set 2nd digit and 3rd digit of the dip switch (DSW1) on the IR Receiver Kit of the indoor device B (object to be set) to another mode.
   Set the wireless remote controller
   For setting, please refer to wireless remote controller’s Operation Manual.

b. Method to cancel the adjacent unit setting mode

1. Set the IR Receiver Kit
   The adjacent unit setting mode can be cancelled just by setting 2nd digit and 3rd digit of the dip switch (DSW1) on the IR Receiver Kit to OFF.

2. Set the wireless remote controller
   For canceling, please refer to wireless remote controller’s Operation Manual.

About Simultaneous Control of Multiple Units

One IR Receiver Kit can be used to control simultaneously a number of indoor units (up to 16 devices). When a number of indoor devices are installed in a large room, one single wireless remote controller can be used to run and stop all these devices.

NOTE:
When a number of units are under simultaneous control, all their indoor devices shall be placed in the same room. If using one wireless remote controller to control air conditioners in more than two rooms, it is possible to forget to close one.

Set the IR Receiver Kit
In case of simultaneous operation of multiple (up to 16) indoor units by the wireless remote controller, install the IR Receiver Kit only to the unit to be operated. Other units should be the standard units without the IR Receiver Kit. If multiple IR Receiver Kits are required to install, 2 IR Receiver Kits are available at a maximum.

Methods for wire connection and setting for the purpose of simultaneous control of multiple units

1. Method to connect wires between indoor unit
   Perform the connection work as following figure.

2. The signal cable of all units shall not be in parallel with the power cable within the device and shall be fixed with wire buckle at key places. The distance between the signal cable and the power cable shall be at least 30 mm outside the devices. Or, put the signal cable through the protective sleeve, one end of which shall be grounded. When a shielded signal cable is used, one end of the shielding net shall be grounded.

3. Set addresses of all indoor devices.

Method for Test Running with the Wireless Remote Controller

Please test it in accordance with the wireless remote controller’s Operation Manual.
