For 50Hz operation:

For 60Hz operation:

When the power supply to the TOSHIBA MMD-AP0186BHP-TR is reset, the unit performs the following actions:

1. Identification of outdoor unit: The outdoor unit is identified, and control is redirected according to the identification result.

2. Indoor fan speed and air flow direction control availability settings: Settings such as indoor fan speed and air flow direction control availability are replaced on the basis of EEPROM data.

3. Fault code clearing: If the power supply reset is performed after a fault, the check code is cleared. If the abnormality persists after the Start/Stop button on the remote controller is pressed to resume operation, the check code is redisplayed on the remote controller.

The operation mode of your TOSHIBA MMD-AP0186BHP-TR changes in response to a command issued via the remote controller. The available commands and their functions are:

The TOSHIBA MMD-AP0186BHP-TR has a check function to test the indoor unit’s operation singly, without communication with the remote controller or the outdoor unit. This should be used for short periods to avoid causing equipment trouble.

How to operate:

1. Short-circuit the CHK pin (CN71 on the indoor P.C. board). The operation mode will differ depending on the unit’s status at that time:

– Normal time: Both float switch (SW) and fan motor are normal.

– Abnormal time: Either the float SW or fan motor is abnormal.

2. During normal time only, if you also short-circuit the DISP pin (CN72 on the indoor P.C. board), you can set the indoor PMV to its minimum opening degree (30 pls). When the DISP pin is open, the maximum opening degree (1500 pls) can be obtained.

How to clear:

Open the CHK pin. The system will stop once but will automatically return to operation after several minutes.

To set the indoor unit function DN code on your TOSHIBA MMD-AP0186BHP-TR, you must use a wired remote controller and the system must be at rest. Follow these steps:

Step 1. Push the SET, TEMP up, and CL buttons simultaneously and hold for at least 4 seconds. The display will show the address of the header indoor unit, and the fan and louver of the selected unit will move.

Step 2. Each time you press the UNIT LOUVER button (left side), one of the indoor unit numbers under group control is displayed in turn. The fan and louver of the selected unit will move.

Step 3. Use the TEMP buttons to select the desired CODE No. (DN code) of the function you want to change.

Step 4. Use the TIME buttons to select the desired SET DATA associated with the selected function.

Step 5. Push the SET button. The display will change from flashing to steady.

– To change the selected indoor unit, go back to step 2.

– To change the selected function, go back to step 3.

Step 6. When the TEST button is pushed, the system returns to its normal off state.

You can perform a test run on your TOSHIBA MMD-AP0186BHP-TR using either a wired or wireless remote controller.

In case of a wired remote controller:

1. Push the [CHK] button for 4 seconds or more. [TEST] will be displayed, and the unit will enter Test run mode.

2. Push the [ON/OFF] button.

3. Use the [MODE] button to set the mode to [COOL] or [HEAT]. Do not use any other mode.

4. The temperature cannot be adjusted during the test run. An error will be detected as usual. A frequency fixed operation is performed.

5. After the test run, push the [ON/OFF] button to stop the operation.

6. Push the [CHK] button to clear the test run mode. The [TEST] display will disappear, and the status will return to normal.

In case of a wireless remote controller:

1. Push the TEMPORARY button for 10 seconds or more. You will hear a “Pi!” sound, and the operation will change to test run. After approximately 3 minutes, a cooling operation will start forcibly. Check that cool air is blowing. If it doesn’t start, check the wiring.

2. To stop the test operation, push the TEMPORARY button once again (for about 1 second).

To access the error history (up to four errors are stored) on your TOSHIBA MMD-AP0186BHP-TR, follow this procedure while the system is at rest:

Step 1. Invoke the SERVICE CHECK mode by pressing the CHECK and SET buttons simultaneously and holding for at least 4 seconds.

Step 2. The letters “SERVICE CHECK” will light up, and the check code “01” will be displayed, indicating the most recent error. This will be accompanied by the indoor unit number to which the error is related and the specific check code.

Step 3. To view other error history items, press the TEMP up/down buttons to select another check code. The codes range from “01” (latest) to “04” (oldest).

Step 4. When you are finished, press the ON/OFF button to return to the normal display.

REQUIREMENT: Do not push the CL button, as this will erase the entire error history of the indoor unit.

Clearing an error of the outdoor unit:

This procedure clears the currently detected outdoor unit error for the refrigerant line connected to the indoor unit controlled by the remote. The indoor unit error is not cleared.

1. Push and hold the CL and TEST buttons for 4 seconds or longer to enter the service monitoring mode.

2. Push the TEMP button to set CODE No. to “FF”.

3. The display will count down from “0005” to “0000” at 5-second intervals. The error is cleared when “0000” appears.

4. Push the TEST button to return the display to normal.

Clearing an error of the indoor unit:

Push the ON/OFF button on the remote controller. Only the error of the indoor unit controlled by this remote controller will be cleared.

You can use the service monitoring mode to check sensor temperatures or the operation status of the remote controller, indoor unit, and outdoor unit.

Step 1. Push and hold the TEST and CL buttons for 4 seconds or longer to enter the service monitoring mode. The service monitor will light up, and the temperature for CODE No. 00 will appear first.

Step 2. Push the TEMP button to change to the CODE No. of the item you wish to monitor.

Step 3. Push the left part of the UNIT LOUVER button to change the item to monitor. This allows you to view the sensor temperature or operation status of the indoor and outdoor units in the refrigerant line.

Step 4. Push the TEST button to return the display to normal.

To read the setting data from the EEPROM, including factory settings and any modifications, follow these steps:

1. Push the SET, TEMP up, and CL buttons simultaneously and hold for at least 4 seconds. In group control, the first unit number displayed is the header unit’s. The CODE No. (DN code) 10 will also be displayed, and the selected unit’s fan will turn on.

2. Each time the UNIT LOUVER button (left side) is pushed, the next indoor unit number in the group is displayed. The selected unit’s fan will operate.

3. Use the TEMP buttons to move the CODE No. up or down.

4. Change the CODE No. from 10 to 01 (for filter sign lighting time) and jot down the setting data displayed.

5. Change the CODE No. using the TEMP button and jot down the setting data for that code.

6. Repeat step 5 until all necessary setting data has been recorded. The DN codes range from 01 to FF.

7. When finished, push the TEST button to return the system to its normal off state. It may take about a minute for the system to become responsive.
