The Web-Thermograph Relay is designed to prevent excessive energy-consuming cooling. This compact box archives and makes long-term values available and graphs trends, so that undesired fluctuations can be more easily recognized. And when your desired upper or lower temperature limit is exceeded, the built-in digital relay output can be switched to turn on a fan for additional cooling or a heater as freeze protection.The temperature values and the digital relay output are displayed on the start page of the unit in a clearly structured graphic.
