Temperature controller for standard rail mounting, 0…11 °C
Electronic temperature controller for controlling and monitoring the temperature in halls, greenhouses and underfloor heating systems. Frost protection locks when the temperature drops. The device has a sensor break and sensor short-circuit protection as well as a “heating” display. Sensors are not included in the scope of delivery. All sensors with the number 0 can be used, e.g. KF-0. Hysteresis approx. 1.5 K.
