How to set the room temperature sensor

•The room temperature sensors are equipped in the indoor unit and the wireless remote controller. One of two sensors works.

•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

Requirement

The control by two remote controllers is enabled by installing the wireless remote controller with the wired remote controller for an indoor unit.

(Max. 2 remote controllers of wireless or wired are installable.)

“2-remote controllers” controlling means that one or multiple units are operated by the multiple remote controllers.

NOTES :

1.	Upon confirmation of the terminal numbers of the indoor unit, connect the remote controller cables
	without miscabling. (If applied AC 220–240 Volt, damage the unit.)
2.	The multiple wireless remote controller kits cannot concurrently be used for an indoor unit.

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.

3. When installing simultaneously the wireless remote controller with the wired remote controller, set
one of them as the sub remote controller.
•	When setting the wired remote controller as the sub, exchange the address connector at the rear
	of P.C. board of wired remote controller from master to sub remote controller.
•	When setting the wireless remote controller as the sub, turn No.3 of DIP switch [S003] on P.C.
	board of wireless remote controller sensor unit from OFF to ON.

To operate an indoor unit by 2 remote controllers
