- Connect the 115V AC power supply to the designated power terminals.
- Connect temperature sensors to the sensor input terminals. Ensure correct polarity if applicable.
- Connect control outputs (e.g., compressor, fan, defrost) to the respective relay terminals. Observe maximum current ratings for each output.
- Ensure all connections are secure and properly insulated.
Note: Incorrect wiring can damage the unit and void the warranty. If unsure, consult a qualified electrician.
5. Operating Instructions
Once installed and powered, the controller will display the current temperature. The front panel typically includes a digital display and several buttons for operation.
5.1 Front Panel Controls
- SET Button: Used to access and confirm parameter settings.
- Up/Down Arrows: Used to navigate menus and adjust values.
- Function Buttons: May include buttons for manual defrost, fan control, or alarm reset, depending on the specific model configuration. Refer to the detailed product sheet for specific button functions.
5.2 Setting the Temperature Setpoint
- Press the SET button. The current setpoint value will flash on the display.
- Use the Up or Down arrow buttons to adjust the setpoint to the desired temperature.
- Press the SET button again to confirm the new setpoint. The display will return to showing the current temperature.
5.3 Accessing and Adjusting Parameters
Advanced parameters (e.g., differential, alarm limits, defrost cycles) can be accessed through a specific key combination or by holding the SET button for an extended period. Consult the full technical manual for a complete list of parameters and their adjustment procedures.
6. Maintenance
The Danfoss AK-CC210 controller is designed for reliable operation with minimal maintenance. Regular checks can help ensure optimal performance.
- Cleaning: Periodically clean the front panel with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Connections: Annually inspect wiring connections for tightness and signs of corrosion. Ensure power is disconnected before inspection.
- Sensor Check: Verify sensor readings periodically against a calibrated thermometer if accuracy is critical.
Caution: Do not attempt to open the controller casing, as this may expose live components and void the warranty.
