nVentilating fan control from remote controller

[Function]

•The start/stop operation can be operated from the wired remote controller when air to air heat exchanger or ventilating fan is installed in the system.

•The fan can be operated even if the indoor unit is not operating.

•Use a fan which can receive the no-voltage A contact as an outside input signal.

•In a group control, the units are collectively operated and they can not be individually operated.

(1)Operation

Handle a wired remote controller in the following procedure.

∗Use the wired remote controller during stop of the system.

∗Be sure to set up the wired remote controller to the header unit. (Same in group control)

∗In a group control, if the wired remote controller is set up to the header unit, both header and follower units are simultaneously operable.

1	Push concurrently SET + CL + TEST buttons for 4 seconds or more.
	The unit No. displayed firstly indicates the header indoor unit address in the group control.
	In this time, the fan of the selected indoor unit turns on.
2	Every pushing	UNIT	button, the indoor unit numbers in group control are displayed succes-

sively.

In this time, the fan of the selected indoor unit only turns on.

Using the setup temp		or	button, specify the item code !.
Using the timer time	or		button, select the setup data. (At shipment: )

The setup data are as follows:

Setup data	Handling of operation of air to air heat exchanger or ventilating fan

	Unavailable (At shipment)

	Available

5 Push SET button. (OK if display goes on.)

•To change the selected indoor unit, go to the procedure 2 ).

•To change the item to be set up, go to the procedure 3 ).

6 Pushing TEST returns the status to the usual stop status.
