The universal temperature switch (thermometer) is ideal for all applications where temperature control is required in heating or cooling operations. Its external, plug-in temperature sensor measures ranges from -55 to +125 °C. The switching temperature is adjustable in 1 °C increments. A 12.7 mm large 7-segment display shows the on and off temperatures as well as the current temperature. A red LED indicates "Heating," a yellow one indicates "Cooling," and another lights up when the relay is activated. The electronic thermostat is not only clear and easy to use but also safe in operation - sensor short circuits and sensor interruptions are detected immediately. The built-in module can be used independently but also serves as a replacement for defective mechanical thermostats or digital thermometers. The connection cable can optionally be extended up to 50 m.
