Programmable Temperature Controllers

Programmable Temperature Controllers are microprocessor based program controllers which stores a maximum of 256 segments in 16 patterns (16 segments per pattern ).

Programmable Temperature Controllers are compact 96 mm (4" ) Square DIN size unit that features a unique touch key panel which allows the display section of the front panel to be used not only for setting but also for data entry.

Programmable Temperature Controllers Features:

• Advanced ramp and soak

• Large memory storage ....16 patterns/ 16 segments
• Autotuning learning function
• Easy programming with unique touch key
• Compact size 96 x 96 mm
• Audible verification of key operation
• Setting lock function for security operation mode
• Mode indicators RESET RUN FIX MAN SET enable easy monitoring
• Program pattern card simplifies program pattern checking
• 3 year warranty
