ITR 79.504
Temperature controller for standard rail mounting, 0…60…°C
Electronic temperature controller for controlling and monitoring temperatures in cooling systems. The device has a sensor failure and sensor short circuit fuse and a “cooling” display. The sensor is not included in the delivery. All sensors with the number 4 can be used, e.g. KF-4. The hysteresis can be adjusted between approx. 0.5…5K.
