Mitsubishi Emergency Cool Mode is a feature that allows the air conditioning unit to operate in the event of a malfunction or failure of the remote controller. This mode can be activated using the Emergency Operation switch, which is located on the indoor unit. When the switch is pressed, the unit will operate in order of Emergency Cool Mode, Emergency Heat Mode, and Stop Mode. However, when the Emergency Operation switch is once pressed, the unit will operate in test run for 30 minutes, and then the operation mode shifts to Emergency Mode.
Understanding Mitsubishi Emergency Cool Mode
Activation of Emergency Cool Mode
The Emergency Cool Mode can be activated by pressing the Emergency Operation switch, which is typically located on the indoor unit of the Mitsubishi air conditioning system. This switch is designed to provide a backup control mechanism in case the remote controller fails to function properly.
Operation Sequence
When the Emergency Operation switch is pressed, the unit will go through the following sequence of operation modes:
- Emergency Cool Mode: The unit will start operating in the Emergency Cool Mode, providing cooling to the space.
- Emergency Heat Mode: If the Emergency Cool Mode is not required, the unit will switch to the Emergency Heat Mode, providing heating to the space.
- Stop Mode: If neither cooling nor heating is required, the unit will enter the Stop Mode, effectively shutting down the system.
It’s important to note that once the Emergency Operation switch is pressed, the unit will operate in a test run for 30 minutes before shifting to the Emergency Mode.
Predetermined Settings
When the Emergency Cool Mode is activated, the unit will operate with the following predetermined settings:
- Set Temperature: The set temperature is fixed at 75°F (24°C).
- Fan Speed: The fan speed is initially set to High during the 30-minute test run, and then it shifts to Medium speed after the test run is completed.
- Coil Frost Prevention: The coil frost prevention feature will still function, even in the Emergency Cool Mode, to ensure efficient and reliable operation.
Limitations
It’s crucial to understand that when the Emergency Cool Mode is activated, the remote-control operation mode is not available. The unit will continue to operate in the Emergency Mode until the issue with the remote controller is resolved.

Mitsubishi air conditioning systems use refrigerants, which must be handled with care. Proper training and certification are required for anyone performing refrigerant-related tasks, such as charging, recovering, or replacing the refrigerant.
Maintenance and Servicing
Regular maintenance and servicing of the Mitsubishi air conditioning system are crucial to ensure its optimal performance and longevity. This includes tasks such as cleaning the air filters, checking the refrigerant levels, and inspecting the system components for any signs of wear or damage.
Troubleshooting
In the event of a malfunction or failure, it’s essential to follow the manufacturer’s troubleshooting guidelines to identify and resolve the issue. This may involve checking the electrical connections, verifying the refrigerant levels, or replacing faulty components.
Conclusion
Mitsubishi Emergency Cool Mode is a valuable feature that provides cooling during emergency situations when the remote controller is not functioning properly. By understanding the activation process, operation sequence, and predetermined settings, users can effectively utilize this mode to maintain comfort in their living or working spaces. However, it’s crucial to adhere to the manufacturer’s guidelines and safety protocols when dealing with the Mitsubishi air conditioning system to ensure its safe and reliable operation.
