Temperature controller for standard rail mounting, 35…95…°C

ITR 79.405

Temperature controller for standard rail mounting, 35…95…°C

Electronic temperature controller for controlling and monitoring of temperatures in halls, greenhouses and underfloor heating systems. The device has a sensor failure and sensor short circuit fuse and a “heating” display. The sensor is not included in the delivery. All sensors with the number 5 can be used, e.g. KF-5. The hysteresis can be adjusted between approx. 0.5…5K.
Art.-Nr.: D4780181
