9.18 XR75CX 5.6
The XR75CX is a microprocessor based controller, suitable
for applications on medium or low temperature ventilated
refrigeration units. It has four (4) relay outputs to control
compressor, fan, and defrost, which can be either electrical or
reverse cycle (hot gas) and light (configurable).
It can also have up to four (4) NTC, CtC (EU or US type) probe
inputs. The first probe is used for temperature control. The
second probe is used to control the defrost termination
temperature at the evaporator. One of the two (2) digital
inputs can operate as a third temperature probe. The fourth
probe is used to control the condenser temperature (for
condenser alarm management) or to display a temperature
value. Set the PbC parameter to CtC to support standard
Copeland temperature sensors (factory default).
The controller is fully configurable through special
parameters that can be easily programmed through the
keyboard.
