Quickstart

Switch on the Condair Cube: To do this, press the power button inside the cavity on the lower, left side of the cube (see product overview).
Note:
When the Condair Cube is plugged in via the USB cable, it switches on automatically. Fully charge the device before using it for the first time.
Place the Condair Cube upright in the room where you want to check the room air. The Cube must be placed as shown in the figure below, so that the sensor on the back of the Cube is reached by the room air and the excess heat can escape through the ventilation slots.
Once the Condair Cube is in place, it requires an adjustment time of approx. 20 minutes until all values are displayed correctly. In particular, the temperature may deviate during the first phase after switching on, since the sensor is not yet at operating temperature.
When the Condair Cube is put into operation for the first time, it must be calibrated. This procedure is described in chapter 5.

---|---
Yellow circle:| Ambient temperature is rather low or high. (value is ≥ 17 and < 20 °C or ≥ 23.5 and < 27 °C) (value is ≥ 62.5 and < 68 °F or ≥ 74.5 and < 80.5 °F)
Red circle:| The comfortable temperature range is undershot or overshot. (value is < 17 °C or ≥ 27 °C) (value is < 62.5 °F or ≥ 80.5 °F)

Note:
Please note that the sensor requires an adjustment time of up to 20 minutes after switching on, a reset or when moving to a different location, until the temperature reading is displayed correctly

Application overviews

View health chart

The range “healthy” represents the air quality, which provides increased health protection and is perceived as pleasant.
The ranges “healthy, “acceptable” and “critical” are distinguished.

The aim is that the current measured value (red point) of the room air is in the inner green diamond and thus in the “healthy” range.

In the upper area of the view, the currently measured CO2 content of the room air is displayed in a bar view. If the current measured value is outside the green range, the room should be ventilated to reduce the CO2 content in the room.

Note:
If the currently measured value is displayed as a gray dot at the edge of the diagram, it indicates that the measured value is outside the displayed range.

View historical readings

This view shows the course of the measured room temperature over a maximum of 4 hours.

For every 10 minutes of measurement, a bar is displayed which shows the average value measured. This is colored according to the described traffic light system. See chapter chapter 4.2.1. If the bar is yellow or red, the temperature was too low ortoo high on average over the last 10 minutes, taking the health chart into account.
A 4-hour chart is available for all measured values of CO2, temperature and humidity.
These views are accessible via the arrow keys on the side of the circle.

Settings

Via the 3 icons you can call the different submenus:
– Alarm settings
– Calibration CO2
– Setting °C / °F
– Time and date settings
Tap once on the respective icon to enter the submenus

Calibration

For accurate measurement results of the CO2 content, the Condair Cube must be calibrated regularly. Two different calibration options are available:
– Auto calibration
– Manual calibration

Manual Calibration

To calibrate the sensor manually, proceed as follows:

Menu Settings Calibration CO2
Place the sensor outdoors, for example outside the window in fresh air. Outside air is used as a reference, since it normally has a value of approx. 400 ppm.
Press “Start” to start calibration. 12 Calibration
The measurement takes approx. 3 minutes This is displayed graphically with a bar graph and a percentage. The sensor resets its CO2 value several times during this time.
After the calibration is completed, the Cube automatically switches to the main page.
Check the CO2 value. If it is within the range of 400 +/-25 ppm, the calibration was successful. If the value is above or below this, repeat the calibration.

Important:
The sensor must be calibrated during the first start-up. Also, if you place the Cube in a new geographical location, it must be recalibrated for accurate measurement results.

Auto calibration

By default, the auto calibration is activated, whereby the sensor calibrates its value independently. It is important here that the sensor is in operation as permanently as possible and is exposed to fresh outside air at least once a week (approx. 10 min).
During auto-calibration, the lowest measured value over one week is taken as the reference value and recalibrated to 400 ppm.

Note: This setting is also saved when the cube is switched off.

Menu Settings Calibration CO2
Auto calibration
Enable or disable auto calibration

If the Condair Cube is not operated permanently and a weekly 10 min fresh air supply cannot be guaranteed, it is recommended to deactivate the auto calibration and to perform the manual calibration.

Time and date setting

The Condair Cube has an internal RTC (RealTimeClock) which is used for the time and date display. Time and date run for approx. 2 months when the unit is switched off and without charging the Cube. Afterwards, both must be reset.

Follow the procedure below to reset the time and date:

Menu → Settings → Time and date settings
Set the desired time using the up/down arrow keys.
The time format is defined as follows:
hh:mm:ss (Hours:Minutes:Seconds)
Confirm the entry with “Ok”.
Enter the desired date in the next screen.
The date format is defined as follows:
dd:mm:yy (Day:Month:Year)
Confirm the entry with “Ok” to complete the date entry.

Conversion degrees Celsius / degrees Fahrenheit

The Condair Cube can display the temperature in either degrees Celsius or degrees Fahrenheit.

Menu Settings Setting degrees Celsius / degrees Fahrenheit
Switch between degrees Celsius / degrees Fahrenheit by pressing the icon. The set value is displayed in the lower gray box with °C or °F.

Options

SD card

An optional memory card can be integrated via the SD card slot on the right side of the Cube. If a memory card is detected during the start-up process, the measured values are saved to the memory card every minute. With the help of Excel, this data can be displayed and analyzed.

Recommended memory card:
SANDISK microSDXC 16GB+AD memory card (16 GB, 98 MB/s, grey/red) or similar.

Power bank

To extend the battery life of the Condair Cube, you can use any power bank with a 5V USB connection.

Display on large screen

It is possible to connect the Condair Cube to an external monitor via a PC. To do this, connect the Condair Cube to the PC via the USB cable and install the necessary drivers. Then open the Condair Cube Tool to start the display on an external monitor. The values are updated at intervals of 30 seconds.

Note:
The minimum resolution for correct display of the values is 1024×768. Note that individual setting of zoom factors may have the negative effect on the display.
