Instruction manual
The CX family (32x74mm) has new functions plus an innovative and attractive design. The revolutionary introduction of 6 keys allows the user direct access to all main functions rapidly and intuitively, while the display with illuminated icons allows an instant view of the machine’s status.
 
Regulation stop by auxiliary probe (beer dispenser applications); it is possible to supervise the tube temperature, stopping the compressor when the temperature becomes too low, and restarting when the correct values have been restored.
Max and Min temperature or HACCP function.
Virtual probe for air on / air off application; used in multideck applications where it is important to regulate temperature using the average of 2 temperatures.
Condenser temperature management to prevent critical situations in the system.
Real time clock.
TTL serial connection for monitoring systems (direct for XR35/75/77CX or through XJ485CX).
