When the outdoor temperature is above10 °C, the reduction is 100%. The lower the outdoortemperature, the less the temperature reduction. Whenthe outdoor temperature is below the set limit, there isno temperature reduction.The comfort and the saving temperatures are set in the displayoverviews. The difference between the comfort and the savingtemperature is considered to be 100%. Depending on the outdoortemperature, the percentage value can be lower according to theset value in ‘Auto saving’.Reduction100%0%-20 -10-29 0 2010Outdoortemp. °CAuto savingExample:Outdoor temp.: –5 °CDesired room temp. in Comfort mode: 22 °CDesired room temp. in Saving mode: 16 °CSetting in ‘Auto saving’: –15 °CThe drawing above illustrates that the reduction percentage at anoutdoor temperature of –5 °C is 40%.The difference between Comfort and Saving temperature is (22–16)= 6 degrees.40% of 6 degrees = 2.4 degreesThe ‘Auto saving’ temperature is corrected to (22–2.4) = 19.6 °C.Boost 11012Circuit Setting range Factory setting1 OFF / 1 ... 99% OFFShortenstheheating-upperiodbyincreasingthedesiredflowtemperatureby the percentage you set.OFF: The boost function is not active.1-99%: The desired flow temperature is increased temporarilywith the set percentage.In order to shorten the heating-up period after a savingtemperatureperiod, thedesiredflowtemperaturecanbeincreasedtemporarily (max. 1 hour).
