SWE:ON · Indoor fan is running high speed. SW6-1:ON · Emergency operation of cooling mode. SW6-1,2:ON · Emergency operation of heating mode.

3.Before you activate emergency operation, check the following points: (1) Emergency operation cannot be activated when:

· The outdoor unit malfunctions. · The indoor fan malfunctions. (2) Emergency operation becomes continuous only by switching the power source on / off. ON / OFF on the remote control or temperature control etc. does not function. (3)

Avoid operating for a long time when the outdoor unit begins defrosting while emergency operation of the heating is activated, because it will start to blow cold air. (4) Emergency cooling should be limited to 10 hours maximum (The indoor unit heat exchanger may freeze). (5) After emergency operation has been deactivated, set the switches etc. to their original positions.

▲▲▲

After completing installation and the wiring and piping of the indoor and outdoor units, check for refrigerant leakage, looseness in the power supply or control wiring, wrong polarity, and no disconnection of one phase in the supply. Use a 500-volt megohmmeter to check that the resistance between the power supply terminals and ground is at least 1.0M

12-5. POWER OUTAGE AUTOMATIC RECOVERY OPERATION

• Whenever a power outage or switching of the power supply causes the power supply of an operating air conditioner to go from OFF to ON, this function will automatically restore the operation of the air conditioner to its previous operating mode.

* If the power is turned from OFF to ON when the air conditioner is not in operation, the air conditioner will not automatically

be turned on. However, the timer operation will be cancelled if the air conditioner is in timer operation (including when the unit is waiting for its start time). Setting for timer operation must be performed once again.

• If there is a momentary power outage of less than one second while the air conditioner is in operation, there may not be a

clear determination of whether or not there was a power failure. When it has been determined that there has been a power failure, recovery will take approximately four minutes after the power is restored. Please wait. (Once "PLEASE WAIT" has appeared on the display, a protection system will operate to prevent the unit from restarting for three minutes.)

When it has been determined that there has been no power failure, operation will continue as is.

• Settings can be made by function selections from the remote controller.

• When there is group control, selection of all refrigerants is required.

12-6. INDIVIDUAL CONTROL OPERATION FROM A SEPARATE ROOM

• By simply centralizing the remote controllers installed in each room in a separate control room, individual control or central-

ized monitoring of the air conditioners in each room can be attained.

• Air conditioner control can be performed up to a total of 500 meters away by connecting the indoor units and remote con-

trollers with 0.3 to 1.25 mm

2-core cable.

• If a remote controller is installed in a room and control room, refer to the section on operating with two remote controllers.

Indoor unit Indoor unit Indoor unit

Remote controller

Control room room 1 room 2 room 3

12-7. TIMER OPERATION

• Timer operation can be performed by setting the wired timer. Start and stop times can be set in10-minute increments within a

24-hour period.

• When used in combination with the central control remote controller of the M-NET control system for the outdoor unit, one

program timer can be used for individual timer settings for each group of the central control system. (Each timer setting can be stored in data memory so timer settings for up to 50 groups can be set individually.)

* Please refer to the MELANS catalog or technical information for details about the central control remote controller.
