10.5.4 Eco-Mode 1
Eco Mode1 is an advanced energy saving mode.
Heating is only switched on when the following conditions are met:
• The outside temperature is below the threshold temperature and precipitation was
detected. Heating then runs at the control temperature for 30 minutes (after the last
precipitation event).
• When the outside temperature lies constantly below the threshold temperature and there
was no heating for more than 20h, heating is switched on for 30 minutes as a
precautionary measure in order to thaw any icing.
However, the precautionary 20h-heating only runs if the outside temperature was measured
at below the threshold temperature for the entire period and conditions were constantly
bright for at least 3 hours.
Examples:
Outside temperature constantly below 5°C; no precipitation for more than 24h
Outside temperature constantly below 5°C; with precipitation
