How to install remote controller

NOTE 1 : Avoid to twist the remote controller cable with power supply cable, etc. or to store them in the same metal pipe, otherwise it causes a malfunction.

NOTE 2 : Install the remote controller apart from the generation source of noise.

NOTE 3 : When noise is contained to the unit power supply, counter measures such as mounting the noise filter is necessary.

•When using the remote controller as exposed, install it at the wall surface where it can be fixed.

Requirement to install the

remote controller

Installation place

•	Install the remote controller at a position with height 1 to 1.5m

	be felt.
•	Do not install the remote controller at a place exposed to direct
	sunlight or direct outside air, such as a side of window, etc.
•	Do not install the remote controller at a place behind something

• How to install

For 2 remote controllers, install the remote controllers in the following procedure.

1.	Set one of two remote controllers as the master
	remote controller. (At shipment from factory)
2.	For the other remote controller, exchange the
	remote controller address connector of the
	master to sub remote controller on the P.C.
	board. Under this condition, the other remote

•	Do not install the remote controller in the freezing box or
	refrigerator because water proof or drop-proof is not applied to
	this remote controller.
•	Be sure to set the remote controller vertically on the wall
	surface, etc.

How to select the room temperature sensor

The room temperature sensors are equipped in the indoor unit and remote controller.

One of two sensors works. Usually, the room temperature sensor in the indoor unit is set to work. To select the sensor in the remote controller side, refer to the following procedure.

1.	Keep	, SET , and		CL buttons pushed for 4 seconds or more.
	NOTE) The UNIT No. displayed at the first time is the indoor
		unit address of the master unit in the group control.
	NOTE) Do not push			UNIT	(select) button.
2.	Using the temperature setup buttons					/	, specify
	the item code 0032 .
3.	Using the timer buttons				/	, change the set
	data from		0000 to	0001 .
4.	Push	SET	button.

(OK if the display changes from flashing to lighting)

1.For removal and mounting of the remote controller body and the rear case, refer to the item, “Using as concealed type”.

2.Remove the lead wires wound to the fixing part of lead wires of the remote controller body, remove the connectors, and then connect the remote controller cable (sold separately) to the connector section of the remote controller body. Insert the remote controller cable into the groove and form it, and wind it around the fixing part of lead wires.

Notching the lower case (thin part of the upper center part) with nipper, etc., pull out the remote controller cables from this part. (Fig. A) (Refer to the item, “How to perform cabling of the remote controller”.)

Connect cables of the remote controller after check of terminal No. of the indoor unit so that there is no miswiring. (Do not apply AC 200/230/ 240V to the remote controller.)

3.Fix the remote controller body by two wood screws.

4.Using the cable clips (Accessory of remote controller cable sold separately), fix the remote controller cable to the wall surface.

•For cabling of the remote controller, use the remote controller cable (sold separately).

1.Remove the lead wires wound to the fixing part of lead wires of the remote controller body, remove the connectors, and then connect the remote controller cable (sold separately) to the connector section of the remote controller body. Insert the remote controller cable (sold separately) into the groove and form it, and wind it around the fixing part of lead wires.

2.When using the remote controller cable (sold separately), refer to the Installation Manual attached to the remote controller cable.

• In a case to operate a group control of multiple

indoor units from the remote controllers at two

positions

5.Push button.

The status returns to the normal status. In this time, is displayed in LCD.

NOTE 1 :

When using two remote controllers, the master remote controller is recognized as sensor though the temperature can be set from either master or sub remote controller.

NOTE 2 :

In a group control, the sensor does not work if the group address is not set to the indoor unit of the master unit.

NOTE 3 :

When using the remote sensor together with the remote controller, do not use the sensor of the remote controller.

Remote controller test run setup

1.When the remote controller is used at the first time, it accepts an operation approx. 5 minutes after the power supply has been turned on. It is not a trouble, but is because the setup of the remote controller is being checked.

2.Push key after [TEST] has been displayed on LCD by keeping button on the remote controller for 4 seconds or more.

•During the test run, [TEST] is displayed on LCD.

•The temperature cannot be controlled if [TEST] is displayed.

Do not use [TEST] in a case other than a test run, otherwise an excessive load is applied on the machine.

3.Use [TEST] in one of HEAT, COOL, and FAN operation modes.

NOTE : The outdoor unit does not operate for approx. 3 minutes after the power supply has been turned on or the operation has stopped.

4.After the test run has finished, push button again to check [TEST] on LCD has gone off.

(For this remote controller, a release function of 60 minutes timer is provided to prevent continuous test runs.)

Master and Sub remote controllers are

*operable even if they are installed to any

indoor unit.
