Product description
The Cooperheat CM256 Programmer with 6 Zone Control is a sophisticated temperature control solution developed to enhance the reliability, accuracy, and operational control of multi-zone industrial heating processes. Designed with a powerful microprocessor-controlled programming system, the CM256 allows operators to easily manage up to six independent heating zones, ensuring consistent temperature regulation and repeatable thermal cycles across complex heat treatment setups.
The unit supports six ‘K’ type (Chromel/Alumel) thermocouples, enabling precise temperature feedback from each zone. Its blue graphical LCD screen provides clear, real-time process visibility, while the push-button interface ensures straightforward configuration and operation. Each zone is equipped with an independent control relay, complemented by a dedicated fault relay for improved system monitoring and safety.
The CM256 offers flexible control strategies, allowing users to select between PID control for precise temperature stability or On/Off control for simpler applications. Operators can modify ramp rates and soak temperatures online, and the servo start function enables the system to begin control from the current process temperature, reducing thermal shock and improving process continuity.
Overall, the Cooperheat CM256 Programmer is a powerful, flexible, and user-friendly solution for precise multi-zone temperature control in industrial heat treatment, resistance heating, and thermal processing environments.

Frequently asked questions
What is the Cooperheat CM256 Programmer with 6 Zone Control used for?
The Cooperheat CM256 Programmer is used to control and monitor up to six independent heating zones in industrial heat treatment and thermal processing applications. It ensures accurate temperature regulation, synchronized multi-zone control, and reliable execution of complex heat treatment cycles.
How many heating zones can the CM256 temperature programmer control?
The CM256 temperature programmer can control six independent heating zones simultaneously. Each zone operates with its own control relay and thermocouple input, allowing precise and individual temperature management across multi-zone heat treatment setups.
What control modes are available in the Cooperheat CM256 Programmer?
The CM256 supports both PID control and On/Off control modes, which are user selectable. PID control provides precise temperature stability for critical heat treatment processes, while On/Off control offers a simpler control method for less demanding applications.
Can the Cooperheat CM256 Programmer be integrated with other controllers?
Yes, the CM256 features a Master/Slave cascading facility, allowing multiple controllers to be linked together. This enables expanded multi-zone control for large-scale heat treatment operations requiring coordinated temperature management across numerous heating zones.
