    3.12 Temperature and Pressure Parameter Values All parameters that indicate a temperature or pressure can be expressed in degrees Celsius/bar or Fahrenheit/PSI, according to parameter Ec41 that sets the unit of measurement. Modifying the Ec41 parameter from Celsius/bar to Fahrenheit/PSI and vice versa does not involve an automatic update of the parameters from one unit of measurement to the other.

  • Page 23: Kind Of Operation

    A high superheating value means that the gas flow passing in the evaporator is insufficient and the evaporation process ends before reaching the end of the evaporator. The valve must be opened to increase the gas flow. A low superheating value means that the gas flow passing in the evaporator is excessive and the evaporation process does not end before reaching the end of the evaporator.
  • Page 24 7.1.1 Manual mode If manual mode has been selected (par. Et2/Et5), the controller will bring the valve to the number of steps set in parameter Et3/Et6 while remaining in that position; opening and/or closing valve are not active. This can be helpful during the set-up of the machine or in case of maintenance. 7.1.2 Adjustment mode Only at start-up, regardless of the mode of operation, the valve will be completely closed by reaching the maximum number of steps of the Ec13/Ec22 valve plus the extra steps for the complete closure...
  • Page 25 during the initial stage, during the Et53 / Et55 time calculated from ▪ when the defrost starts, if the adjustment of the valve requires an aperture value below the step number set under parameter Et52 / Et54, the valve will not close at a value below Et52 / Et54 (which is therefore the minimum aperture threshold in the initial defrost stage).
