0th position of the voltage curve. This ensures reduced relay contact welding, increased relay life and reduced switching noise. This feature should only be used when the compressor is directly driven by the EET relay and no external contactor is used. © Danfoss | Climate Solutions | 2023.07 BC320944106159en-000301 | 5... -
Page 6: Compressor Protection Against High Condensing Temperature
Advanced Fan control helps maintain a uniform cooling by switching fan ON and OFF during the compressor OFF cycle. This feature reduces the overall energy consumption while maintaining a uniform temperature in the cabinet. © Danfoss | Climate Solutions | 2023.07 BC320944106159en-000301 | 6... -

The second compressor can be configured to any of the auxiliary relays and might require an external relay, if the rated current of the second compressor is more than the auxiliary relay ratings. © Danfoss | Climate Solutions | 2023.07 BC320944106159en-000301 | 8... -
Page 9: Anti Freeze Function (Applicable For Eeta Only)
This feature helps test all the outputs of the controller instantly when connected to an actual application in the OEM Production line or during field service. The feature can be used when connected to KoolProg or by using MODBUS commands (please contact the Danfoss support team for info about MODBUS commands). Sensor Error handling In the event of cabinet sensor error/ failure, cabinet temperature can be controlled in EET controller using two methods to avoid food spoilage until the failed sensor is replaced. -
