●Reduces maintenance work drastically.●Enables you to check operation data of the indoor and outdoor units by remote controller.

Furthermore, use of maintenance stable-operation control that fixes the operating frequency, allows smooth inspection, even forinverter models.

1. Maintenance Mode Operating Method* If you are going to use the " 2. Guide for Operation Condition ", set the airflow to "High" before activating maintenance mode.

● Switching to maintenance modeMaintenance mode can be activated either when the air conditioner is operated or stopped.It cannot be activated during test run.

Maintenance information can be viewed even if the air conditioner is stopped.

■Remote controller button information

Operation mode

(1) Press the TEST button for 3 seconds to switch to maintenance mode.[Display ] MAINTENANCE

The outdoor unit features automatic capacity control to provide optimum fan speeds. Therefore, the fan keeps running at a low speed to meet the current outside air condition unless it exceeds its available maximum power. Then, in actuality, the fan may stop or run in the reverse direction depending on the outside air, but this does not mean malfunction.

Check for correct motion of auto-vanes.

Cooling mode: Check if cool air blows and water is drained.Heating mode: Check if warm air blows. (It takes a little while until warm air blows.)

A.Remote control-ler operation(Standard)

B.Remote control-ler operation

Use of 2 con-trollers enablesoperation of the airconditioner bothfrom a distanceand nearby.

C.Group controloperation

Use of 1 remotecontroller to con-trol multiple airconditioners withthe same settingssimultaneously.

* Outdoor unit`s re-frigerant addressneeds to be set.

D.Remote/localcombined controloperation

Allows start/stopof the air condi-tioner from a dis-tance, and prohib-its/permits start/stop from remotecontrollers.

E.Operation byexternal signal

F.Control by externalsignal and remotedisplay

Enables you todisplay the op-eration state andcontrol start/stopfrom a distance.

There are 2 types of remote controllers: wired typeand wireless type.Simultaneous twin, triple and quad units are counted as 1 unit, and the indoor units are started or stopped simultaneously.

Up to 2 remote controllers can be connected toone group.Simultaneous twin, triple and quad units are counted as 1 unit.

Operation control by the latest command (last en-tered priority)Wired and wireless remote controllers can be com-bined as a pair.

One group can consist of up to 16 indoor units, andthey can be started sequentially by connecting theremote controller to them and assigning an addressto each outdoor unit.Simultaneous twin , triple and quad units are counted as 1 unit.All the units belonging to the same group are oper-ated in the same mode, but thermostats can beturned ON/OFF individually for each outdoor unit.Up to 2 remote controllers can be connected.

All the air conditioners can be turned ON/OFF collectivelyfrom a distance.Operation can be switched between the remote operat-ing panel and local controller.Operations (e.g., temperature adjustment, airflow, air-flow direction) except for start/stop operations can beperformed even if operations from the local remotecontroller are prohibited.In the case of simultaneous twin, triple, quad units, connect the controller to one indoor unit only. If connected to 2 or more indoor units, an error may occur.(operation stop)Control by an external timer is possible by connecting it.

Use of optional "remote ON/OFF adapter" enablesremote control via relay. (Level signal)

Extraction of non-voltage contact outputUse of optional "remote operation adapter" and"remote display panel" (Part to be provided at your site) provides non-voltage contact outputs ofsignals (operation, error) and operation/stop input function.

Extraction of DC12 V contact outputUse of optional "Multiple remote controller adapter"and "remote display panel" (Part to be provided at your site)provides DC12 V contact outputs of signals(operation, error) and operation/stop input function.

If simultaneous twin or triple or quad, connect 2 wireless remote controller receivers (one each) to any 2 of the indoor units. All the functions of the indoor unit can be controlled even if different models (different types) are mixed. Do not use crossover wiring among indoor units with simultaneous twin, triple, quad units. (Prohibited item.)In the case of "standard 1:1" connection, it is not possible to connect 2 remote controller receivers to the indoor units. However, with systems consisting of simultaneous twin or triple or quad units, it is possible to connect a remote controller receiver to 2 indoor units. In this case, all the pair numbers will be "0" (intial setting, no change necessary), and all the units will be turned ON/OFF simultaneously. When using 2 or more wireless remote controllers, the display contents on the remote controllers may differ from the actual settings, since the operation mode last by any of the remote controllers will be effective.

If simultaneous twin or triple or quad, connect both the wired remote controller and wireless remote controller receiver to any one of the indoor units. All the functions of the indoor unit can be controlled even if different models (different types) are mixed. Do not use crossover wiring among indoor units with simultaneous twin, triple, quad units. (Prohibited item.)When using 2 or more remote controllers, the display contents on the remote controllers may differ from the actual settings, since the operation mode last by any of the wireless remote controllers will be effective.

3. Group Control Operation (Collective Operation and Control of Multiple Refrigerant Systems (2 to 16))

Multiple Mr.Slim air conditioners can be operated with the same settings (e.g., operation mode, preset temperature, etc.) by using 1 remotecontroller. Each outdoor unit can be turned ON/OFF individually by the intake sensor.Up to 16 refrigerant systems can be controlled as a group by 1 remote controller.A refrigerant address must be set for each outdoor unit. Addresses "0" to "15" can be set with no duplicates. Address "0" must be set for one ofthe outdoor units.

* In the case of simultaneous twin, triple and quad units, only 1 refrigerant system is used.

For 2-remote controller control, refer to "2. 2-Remote Controller Operation". However, when using both wired and wireless remote controllers, receivers must be connected to indoor units that are connected by crossover wiring.Connect an indoor unit having the highest functions among the group to the outdoor unit assigned to refrigerant address "0". <Refer to the examplegiven below> If indoor units with vanes are used with those without vanes, connect the outdoor unit to a unit with vanes.

Function specifications <Example>

In the case of multi type systems consisting of simultaneous twin, triple and quad units, the indoor units should not be connectedby crossover wiring. (Prohibited)

Outdoor unit address settingFor group control, an address must be set for each outdoor unit.To set addresses to outdoor units, use the DIP switch SW1 (3–6) provided on each outdoor control board (initial setting: all are set to "OFF").Address setting by SW1 is as follows.

* Checking the outdoor unit refrigerant addressesTo find the location of an outdoor unit with a specific refrigerant address, specify the address in self-diagnosis mode. The outdoorunit will operate intermittently. (For details on using self-diagnosis mode.)

Group operation by multiple remote controllersUp to 2 remote controllers can be connected to each group. For details, refer to " 2.2-REMOTE CONTROLLER OPERATION".
