Unit Controls
- Warning
- Risk of Injury
- Never operate the unit unless you completely understand the controls; otherwise serious injury may occur.
| 1. Display | It is always active and backlit except when the unit is disconnected (no power) or when the unit is connected but has been manually switched off from the HMI. It normally displays the return air temperature (of both load compartments in multi-temperature units). |
| 2. On/Off Key | This key is used to start/stop the unit. It is always lit except when the unit is disconnected (no power) and thus acts as an indicator of the presence of power in the unit. |
| 3. Select Key | Selects prompt screens and information screens. |
| 4. Up Key | Is used to increase the setpoint temperature. |
| 5. Down Key | Is used to reduce the setpoint temperature. |
| 6. Enter Key | Is used to enter a new command such as manual defrost, etc. |
| 7. Buzzer | It is energised when the vehicle battery and the electric power supply are connected simultaneously. It is also energized if the doors are opened while the refrigeration unit is running. |
| 8. Cool Symbol | (Thermometer with an arrow pointing downward). The unit is cooling. |
| 9. Heat Symbol | (Thermometer with an arrow pointing upward). The unit is heating. |
| 10. °C/°F Symbol | Indicates whether the on-screen temperature reading is in degrees
Celsius (C) or degrees Fahrenheit (F).
Note This icon will appear like a % sign in TK
Battery charging. See (TK Batteries HMI Menu)

| 12. Maintenance Symbol | Warns of the need to carry out maintenance to the unit. |
| 13. Defrost Symbol | Indicates the unit is in Defrost Mode. |
| 14. Electrical Symbol | Indicates that the unit is in Electric Standby. |
| 15. Condenser Defrost Symbol | Indicates the condenser unit is in defrost mode (turns on at the same time as defrost symbol 13). |
| 15. Battery Status | If the unit is connected to shorepower and this symbol is solid, this means that the TK Batteries are charged. if this symbol is blinking, this means that the E-200 is charging the TK batteries. |
| 16. Combined Compartment Symbol | Indicates that the multi-temperature unit is working as a single temperature unit. |
| 17. Unit Derating mode. | Indicates the compressor is running in derating mode. This means that the controller is reducing the power delivered due to a particular battery voltage. When the battery voltage rises sufficiently, this mode is disabled, and this icon will no longer appear. |
