NOTE
• The CODE No. setting cannot be set with a wireless remote controller, simple remote controller, or central control remote controller.
• When installing another option at the same time, use CN4 on the Multi Tenant Kit board.
CN4 is for use instead of the indoor unit option connector CN61, but when Multi Tenant Kit is installed, pin 3 of CN61 is changed from the unit remote controller operation disable
function to the Multi Tenant signal so the unit remote control operation disable function of the other option cannot be used.
• A wired remote controller cannot be operated in multi tenant mode. Operation is also not accepted from another central control remote controller.
• In the case of group operation, install a Multi Tenant Kit and step-down transformer for all indoor units and enable simultaneous operation.
(Communication among the group stops and a check code is displayed.)
• Before configuring the address setting and performing test run, turn on the main power of the indoor unit.
• Be sure to install a step-down transformer for each Multi Tenant Kit. If a step-down transformer is shared by two or more kits, noise will be generated and communication will stop.
• Operation stops when multi tenant mode is cancelled (tenant power is turned on) even if auto restart is set.
• The louver of the indoor unit may open in multi tenant mode but this is not abnormal.
* Multi tenant mode: When tenant power is off
