If a special crimping tool is not used, or if the connection is soldered, insulate the wires using insulation tape. Power wire from receiver unit Wire of receiver unit (field supply) Wire joint CE-1 (provided) Exposed Mounting Connection diagram Indoor unit remote controller terminal board Separate receiver unit Remote controller cord (optional) 80 Requirement The control by two remote controllers is enabled by installing the wireless remote controller with the wired remote controller for an indoor unit. 2 remote controllers of wireless or wired are insatiable. ) "2-remote controllers" controlling means that one or multiple units are operated by the multiple remote controllers. Upon confirmation of the terminal numbers of the indoor unit, connect the remote controller cables without miscabling. The multiple wireless remote controller kits cannot concurrently be used for an indoor unit. When installing simultaneously the wireless remote controller with the wired remote controller, set one of them as the side remote controller. When setting the wired remote controller as the side, exchange the address connector at the rear of P. C. board of wired remote controller from master to side remote controller. When setting the wireless remote controller as the side, turn the switch of wireless remote controller receiver unit from RCU: MAIN to RCU:SUB. To operate an indoor unit by 2 remote controllers The indoor unit is operated if either wireless or wired remote controller is set as master or side remote controller.

The room temperature sensor is set to the indoor unit side at the shipment from the factory. To select the sensor in the remote controller, push the SENSOR button (Right figure) inside of the remote controller cover and check "Main sensor" disappears from LCD. NOTE : If the room temperature data from the remote controller is not transmitted to the unit for 10 minutes or more, the sensor at indoor unit side is automatically selected even if the sensor at the remote controller side is selected. Fix the remote controller toward the unit as possible. Sensor button How to set the address switch When the multiple sensors are installed in the same room, an address can be set to prevent cross communication. When replacing the battery and pushing SET button, the address of the remote controller becomes [ALL] and the sensor is enabled to receive signal regardless of setting of address switch of the operation section. For selecting of the remote controller address, refer to Owner's Manual. Display of remote controller address Address switch position of sensor Address Address Address Address Address switch of sensor unit can be set any position. 82 Wireless remote controller <Operation Manual> Display Section All indicators are shown in the right and the lower figures for the explanation. · When turning on the leakage breaker at the first time 3 minutes later, [SET DATA] flashes about for 1 minute on the display part of the remote controller. While this display is flashing, the model is being automatically confirmed. [. . . ] board A B Indoor unit Indoor unit Remote controller Remote controller 2.
