Always the right temperature thanks to cooling and heating modes. Maintaining the exact required temperature at a constant level is highly relevant for numerous applications: cooling or freezing devices, such as those in supermarkets or large kitchens, require perfect temperature management to keep stored goods fresh for a long time. This built-in controller, suitable for a range of -30 °C to 999 °C, is also ideal for air conditioning systems. The device features a 1-meter sensor cable and two relay outputs. In case of overheating or sensor failure, the controller triggers both an audible and visual alarm, thus protecting against damage caused by incorrect temperature settings.
