Heating systems for frost protection in cold stores and freezer rooms offer a reliable precaution against frost damages and humidity wherever the natural thermal fl ow is not suffi cient for preventing a freezing of humidity in the foundation. For controlling these heating systems, Klöpper Therm developed a new controller offering maximum safety and convenience apart from the approved precise and reliable control. The frost protection controller can easily be confi gured and monitored via web interface. The integrated wake on LAN function enables the booting up of a PC in case of failures (e.g. in a control room) and informs the operating personnel about the type and place of failures.
