1. IMPORTANT USER INFORMATION • symbol is intended to alert the user of a non-insultated voltage source within the product area that is sufficiently high to constitute a risk of electric shock to persons. • symbol is intended to alert the user of important operating and maintenance (servicing) instructions. -
Page 6: Product Disposal (Weee)
• It is good practice to bear in mind the following indications for all Dixell products: Prevent the electronic circuits from getting wet as contact made with water, humidity or any other type of liquid can damage them. Comply with the temperature and humidity limits specified in the manual in order to store the product correctly. -
Page 7: Generalities
3. GENERALITIES The XR-T is a microprocessor-based controller suitable for applications on medium or low temperature ventilated refrigeration units. It has 4 relay outputs to control compressor, fans, light and defrost or auxiliary outputs. The device is also provided with up to 4 NTC, PTC or PT1000 probe inputs. There are up to 2 configurable digital inputs. -

Page 28: Energy Saving
With parameter rCC it is possible to enable the compressor rotation function: the activation of the first and the second compressor will be alternated to equalize the number of working hours of both of them. In case of hot gas defrost operation, it is possible to select if one or both compressors will be used. 7. -
