  • Page 33 DEVIreg™ 850 IV Post-heating If the reason for ending a heating period is a decrease of moisture to below the chosen level, the post-heating period will start. Post-heating ensures that no ice and snow is left on the roof. If system priority is low, heating might be paused at any time! The ground system uses heated sensors which under normal circumstances will hold a temperature of 1.5 °C.
