PARAMETERS REGULATION Differential: (0,1 ÷ 25,5°C / 1÷255 °F) Intervention differential for set point. Compressor Cut IN is Set Point + differential (Hy). Compressor Cut OUT is when the temperature reaches the set point. Minimum set point: (-100°C ÷ SET; [-148F ÷ SET): Sets the minimum value for the set point. Maximum set point: (SET÷150°C/ SET÷302°F). -

Do you have a question about the ULTF 80 and is the answer not in the manual?
Questions and answers
Good afternoon Mr/Mrs, We get a problem with our ULTF 80, in every 2 weeks operation time, the temperature chamber is out of range, overheat. The compressor & condensor is normal. What should we do? Thank you
If the Arctiko ULTF 80 temperature chamber overheats every two weeks despite normal compressor and condenser operation, check the thermostat probe calibration for possible offset and adjust it within the range of -12.0 to 12.0°C. Also, verify if the compressor ON time during continuous cycle (CCt) or faulty probe settings (COn and COF) are causing extended compressor activity. If the issue persists, inspect temperature readings from the internal sensors and ensure proper installation and operation.

@Mr. Anderson Thank you for your response. We have tried re-adjusting the offset from -5.5 to -7.5. Since we are using the G-214 controller, we couldn't find the "****" and "COF" settings, so we are unable to verify the compressor's timing. Permit me to ask again, Mr. Anderson: 1. Current condition: Setpoint = -80°C, Hysteresis = 2°C. However, when the compressor turns on at -79°C, the temperature rises to -76°C. Is this behavior considered normal? 2. In installations, is it acceptable to weld the suction (low-pressure) and discharge (high-pressure) lines together? Or is this condition intended to protect the compressor from excessively low temperatures?(attached) Thank u very much
