7.2.3.11 Maximum level
This setting is required for the "Direct control with steps" and "Differential tem-
perature with steps" operating modes. It specifies, for example, how far a win-
dow should be opened at the maximum stage. The value range is 0...100%.
Turn the touch wheel to set the value "Maximum level".
The function button [
Stand.
] sets the value “Maximum level” to the product-
specific factory setting.
7.2.3.12 Step duration
This setting is required for the "Direct control with steps" and "Differential
temperature with steps" operating modes. It specifies the period after which
switching to the next stage occurs. The value range is 1...100 minutes.
Turn the touch wheel to set the value “Step duration”.
The function button [
Stand.
] sets the value “Step duration” to the product-
specific factory setting.
7.2.3.13 ifference temperature
control
These settings are needed for the operating modes "Enable/disable differ-
ence temperature" and "Difference temperature with steps" of the tempera-
ture control. You can use it to cool and ventilate a room, activating your win-
dow depending on the inside and outside temperature.
The difference temperature control works with four adjustable limit values:
Limit value "WARM" (Max. comfort temperature): It is too warm inside when
the inside temperature exceeds this value. The difference temperature control
is activated to vent and cool the room.
Limit value "COLD" (Min. comfort temperature): It is too cold inside when the
inside temperature falls below this value. The difference temperature control
is deactivated again and the window is closed.
“D-temp COOLER” limit value (cooler outside than inside): If the outside tem-
perature is lower than the inside temperature by at least the set difference
temperature, the window is opened for venting and cooling the room.
“D-temp WARMER” limit value (too hot outside): When the outside tem-
perature is below the inside temperature by no more than the set difference
temperature, the room can no longer be cooled by the warm outside air. The
window is closed again to prevent the room from being heated further by out-
side air that is becoming warmer.
