 GENERALITIES 

The 

XR70T

 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. By using the 

HOT-KEY

 it is possible to program the device quickly and easily. The 

controller implements Full Touch technology.
