Pulse Motor Valve (PMV) Forced Open/Close Function in Indoor Unit
This function is provided to open or close forcedly PMV for 2 minutes in all the indoor units by the switch operation
on the interface P.C. board of the header unit.
This function is also used to open PMV fully when turning off the power and executing an operation.
<Operation>
[Open fully]
Set the switches SW01/SW02/SW03 on the interface P.C. board of the header unit to [ 2/3/1 ], and push SW04 for 2
seconds or more. (Display appears on 7-segment display for 2 minutes as follows.) [P ] [ FF]
[Close fully]
Set the switches SW01/SW02/SW03 on the interface P.C. board of the header unit to [ 2/3/1 ], and push SW05 for 2
seconds or more. (Display appears on 7-segment display for one minute as follows.) [ P ] [ 00 ]
[Clear]
After 2 minutes (1 minutes for “Close fully”) after setting up, the opening automatically returns to the normal opening.
Solenoid Valve Forced Open/Close Function in Outdoor Unit
This function is provided to forcedly open each solenoid valve mounted in the outdoor unit by the switch operation
on the interface P.C. board in the outdoor unit.
Use this function to check there is no refrigerant clogging with ON/ OFF operation of the solenoid valve.
[Operation]
(1) Set the switches SW01/SW02/SW03 on the interface P.C. board of the outdoor unit to [ 2/1/3 ].
(2) When [ H. r ] is displayed in 7-segment display [ A ], keep pushing the switch SW04 for 2 seconds or more.
(3) From when [ 2 ] is displayed in 7-segment display [ B ], SV2 is turned on.
(4) After then, ON and OFF of each solenoid valve are exchanged by changing the setup number of the switch SW02 .
(ON/OFF output pattern of each solenoid valve is as shown below.)
NOTE 1)
Display in 7-segment display [ B ] is exchanged just when the number of SW02 has been changed; on the other
hand, the solenoid valve output is exchanged when SW02 has been kept with the same number for 5 seconds or
more.
NOTE 2)
The mark [ O ] in the table indicates that the corresponding solenoid valve is forcedly turned on.
NOTE 3)
The mark [ - ] in the table indicates that ON/OFF of the solenoid valve is controlled based upon the specifications of
the air conditioner.
NOTE 4)
The mark [ x ] in the table indicates that the corresponding solenoid valve is forcedly turned off with this operation.
NOTE 5)
The case heater output is for both the compressor and accumulator heaters.
* If the outdoor unit has no valve, then 7-segment display [B] shows [ - - ].
[Clear]
Return switches SW01/SW02/SW03 on the interface P.C. board to [ 1/1/1 ].
NOTE) As this function is not based on the specified general control, be sure to release this mode after checking.
