Understanding the functionality of a cooling unit in regards to temperature.
The following is an example of cooling units standard temperature setpoint and the components which will be operational. The factory default temperature setpoint is 95°F. The temperature setpoint can be modified by the customer depending on their application needs.
The cooling cycle of the unit automatically activates when the cabinet temperature exceeds the default setpoint of 95°F, maintaining optimal conditions for sensitive components. The internal fan continues to run, ensuring airflow across the temperature sensor for accurate monitoring. Simultaneously, the compressor and external fan engage to cool the air until the temperature returns to the desired level, preventing overheating and ensuring reliable equipment performance.
Cabinet Temp Below Target Setpoint:
- Internal Fan is always ON to blow cabinet air across the temperature sensor
- Compressor and External Fan are OFF
Cabinet Temp Above Target Setpoint:
- Internal Fan is always ON
- Compressor and External Fan are ON to cool the air
Examples:
Cabinet Temp Below Reference
Internal temp 90ºF Set Point 95ºF
- Internal fan always running
- Air blowing across temp sensor, monitoring conditions
- Compressor and exterior fan are off
- LED sequence “solid green”
- Fault signal contact is closed
Cabinet Temp Above Reference
Internal temp 100ºF Set Point 95ºF
- Internal fan always running
- Air blowing across temp sensor, monitoring conditions
- Controller Set-point Met turning on External fan and compressor.
- Cooling continues until reference met
- LED sequence “solid green”
- Fault signal contact is closed
