ITR 79.503
Temperature controller for standard rail mounting, 0…11…°C
Electronic temperature controller for controlling and monitoring of temperatures in halls, greenhouses and underfloor heating systems. Frost protection locks when the temperature falls. 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 0 can be used, e.g. KF-0. Hysteresis approx. 1.5K.
