Temperature controller for standard rail mounting, 2x 5…30…°C

Temperature controller for standard rail mounting, 2x 5…30…°C

Electronic temperature controller specifically for room temperature control using remote sensor. This device has two separate setpoint adjusters, which make it possible to control a room with two different temperatures by manual switching or depending on time (e.g. using timer). Switching between setpoints is performed via an external potential-free contact. The device has a sensor failure and sensor short circuit fuse. The sensor is not included in the delivery. All sensors with the number 2 can be used, e.g. KF-2. Hysteresis approx. 0.5K.
