5.5 Menu "Room climate" (only "R-Tronic RTFC K")
In comparison with the model "RT B" and "RTF B", the "R-Tronic RTFC K"
features an a CO2 measured value detection. The integrated sensor continu-
ously measures the carbon dioxide content (CO2 value) in the ambient air and
it will be displayed when the defi ned value is exceeded. Excessive CO2 values
have a negative infl uence on the power of concentration and lead to tiredness.
NOTE
The display of the "R-Tronic RTFC K" shows the CO2 values in PPM. A
PPM value of 1,000 is, for instance, equivalent to 1,000 parts (parts per
million) of CO2 per one million parts of room air or a CO2 content of 0.1%.
For comparison: The average CO2 content of outside air amounts to 400
PPM or 0.04%.
The display of the "R-Tronic RTFC K" shows the CO2 content in the ambient air:
(Illustration 70)
Values below 1,000 PPM are considered as standard value for a
"good" room climate. For this reason, the following symbol will
be displayed if this value is exceeded:
This is a recommendation for room ventilation (open window).
The
threshold
above which the symbol will be displayed can be modifi ed via the
menu
ROOM CLIMATE
X
CO2 ALERT THRESHOLD
. This way you may deter-
mine the CO2 level at which the room ventilation recommendation will be displayed.
1. Go to the MAIN MENU. After having pressed the Menu-button you will
reach the submenu TIME PROFILE. Turn the Menu-button to the right
and confi rm the selection ROOM CLIMATE and the following selection
CO2 ALERT THRESHOLD.
2. Select a
PPM value
between
450
and
2,000
and confi rm the selection
SETTING
. The message
SAVED
will shortly appear on the display.

From now on, a recommendation for room ventilation will be shown on
the "R-Tronic" display as soon as your individual CO2 threshold is
exceeded. The symbol will no longer be displayed as soon as the PPM
value will have dropped to a value lying 10% below the set threshold.
Example:
PPM = 1,000, symbol will disappear at a value < 900 PPM
