Main features

Longtime seller temperature controllers

Longtime seller of digital temperature controllers with easy-to-operate PID Autotuning.

Avoids setting errors

This model uses SET key (Registration key) method which avoids setting errors.


PID action is selectable from heat, cool, or heat/cool control.
