Dixell XR20CX-5N1C1 230V/50-60Hz Digital Thermostat Controller Off Cycle Compressor Defrost Programmable-Commercial for Refrigeration

  • ...esigned for refrigeration applications at normal temperature.It provides a relay output to drive the compressor.Suitable for appliances including:for refrigeration applications at normal temperature..
  • COMPRESSOR:The regulation is performed according to the temperature measured by the thermostat probe with a positive differential from the set point: if the temperature increases and reaches set point plus differential the compressor is started and then turned off when the temperature reaches the set point value again. In case of fault in the thermostat probe the start and stop of the compressor are timed through parameters COn and COF..
  • Defrost is performed through a simple stop of the compressor. Parameter ?IdF? controls the interval between defrost cycles, while its length is controlled by parameter MdF..
  • SAFETY PRECAUTIONS Check the supply voltage is correct before connecting the instrument. Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden temperature changes with high atmospheric humidity to prevent formation of condensation. Warning: disconnect all electrical connections before any kind of maintenance. Fit the probe where it is not accessible by the End User. The instrument must not be opene....
