    If the reason for ending a heating period is a decrease of moisture to below the cho- sen level the post-heating period will start. Post-heating ensures that no ice and snow is left on the roof. 32 | © Danfoss | 2019.07 08097083 / VIMHE202...
  • Page 33 If the temperature rises more than 1.5 °C above the chosen melting temperature the system will automatically stop heating the area irrespective of the moisture on the area. 08097083 / VIMHE202 © Danfoss | 2019.07 | 33...

  • Page 35 This will give relatively low energy consumption, but the area may remain wet and icy in short periods. The factory settings are average values providing a relatively high degree of security and moderate energy consumption. 08097083 / VIMHE202 © Danfoss | 2019.07 | 35...
