Security and energy consumption
High security — higher energy consumption
If a high degree of security against ice and snow is wanted, make the following adjust-
ments of the operation parameters:
• Increase the standby temperature
• Increase the melting temperature
• Decrease the moisture level (close to setting 5)
• Prolong the post-heat period
This will give a high degree of security in even dry areas.
Low security — lower energy consumption
Conversely, low energy consumption and a moderate level of security against ice and
snow could be prioritized. In this case make the following adjustments of the operation
parameters:
• Decrease the standby temperature
• Decrease the melting temperature
• Increase the moisture level
• Shorten the post-heat period
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 secu-
rity and moderate energy consumption.
