The electronic thermostat for top hat rail mounting (35 mm) in the format 90 mm x 22.5 mm is used for simple temperature control (heating or cooling). A Pt100zl, Pt1000zl or KTY2X-6 can be used as an input. The actual and setpoint values are shown on the backlit dot matrix display (64 x 80 pixels) with special characters for °C and °F. The timer function can be used to start the thermostat function (heating or cooling) or to limit it for a specific time. The switching state of the relay output as well as the actual and setpoint values are shown simultaneously on the display. The display can be switched between four national languages (German, English, French and Spanish). The device is operated using 4 buttons on the front. The electrical connection is made via print terminals with push-in technology. The voltage supply is DC 12 to 24 V +/-15% / AC 24 V +/-15%, 48..6 3Hz.
