5.14 XR75CX 2.6

Model XR75CX 2.6 (32 mm x 74 mm) is a micropro-

cessor based controller, suitable for applications on
medium or low temperature ventilated refrigeration units.
It has four relay outputs to control compressor, fan, and
defrost, which can be either electrical or reverse cycle (hot
gas) and light (configurable). It can have a Real Time
Clock (RTC) that allows programming of up to six daily
defrost cycles, divided into holidays and workdays. A
“Day and Night” function with two different setpoints is
fitted for energy saving.

It can also have up to four NTC or PT1000 probe

inputs; the first one for temperature control and the second
probe is located on the evaporator to control the defrost
termination temperature and to manage the fan. One of the
two digital inputs can operate as a third temperature probe.
The fourth probe is used to signal the condenser
temperature alarm or to display a temperature value.

The RS485 serial output enables the unit to be

connected to a network line that is MODBUS-RTU
compatible, such as the monitoring units of the XWEB
family. The Hot Key receptacle allows the controller to be
programmed by means of the Hot Key programming
keyboard.

The controller is fully configurable through special

parameters that can be easily programmed through the
keyboard.
