65 Ventilating fan control from remote control[Function]• The start/stop operation can be operated from the wired remote control when air to air heat exchanger orventilating 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. OperationHandle a wired remote control in the following procedure.∗ Use the wired remote control during stop of the system.∗ Be sure to set up the wired remote control to the header unit. (Same in group control)∗ In a group control, if the wired remote control is set up to the header unit, both header and followerunits are simultaneously operable.1 Push concurrently SET+ CL+ TESTbuttons 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 LOUVERbutton (button of left side), the indoor unit numbers in group control aredisplayed successively.In this time, the fan of the selected indoor unit only turns on.3 Using the setup temp or button, specify the CODE No. 31 .4 Using the timer time or button, select the SET DATA.
