(Indoor/outdoor cannot communicate before address setup. ) There is none of outdoor terminator resistor, or there are two or more resistances. (Before address setup) E20-01 Address setup is performed with connecting indoor/outdoor communication line. ON 12 Remote controller status No response Countermeasures Set up addresses. (In order of indoor ® outdoor) Correct wiring. Check SW30 bit 2 of the outdoor unit. No connection between multiple refrigerant lines: SW30 bit 2 0N. Connection between multiple refrigerant lines: SW30 bit 2 of the connected outdoor unit is turned on only in one line. Correct wiring. SW30 Address setup is performed under condition of connecting between multiple refrigerant lines. 3 There is no display of a check code on 7-segment display on the interface P. C. board of the outdoor unit though there is indoor unit which does not accept the operation from the remote controller. 7-segment display of outdoor unit None Cause Communication line is not connected between indoor and outdoor. (Unit which does not response to remote controller) The power of the header unit of the group is not turned on in indoor group control. (Unit which does not response to remote controller) Group address is set up to follower unit in the individual control. (Unit which does not response to remote controller) Modify wiring. Push the temperature setup / buttons to select the item number (Item code) to be monitored. For displayed codes, refer to the table below. Push UNIT button to change the item to one to be monitored.

[. . . ] 1 to 9 unit Indoor individual start/stop (ON/OFF) function 8 Pulse Motor Valve (PMV) Forced Open/Close Function in Indoor Unit This function is provided to fully open or close forcibly the PMV for 2 minutes in all indoor units, using the switch operation on the interface P board of the outdoor unit. This function is also used to open the PMV fully when turning off the power and executing an operation, for example, vacuuming. Operation [Open fully] Set the switch SW01 on the interface P board of the outdoor unit to [2], SW02 to [3], SW03 to [1] and push SW04 for . C.
