SETTING UP:

1.Open the battery cover at the back of the transmitter and open the battery cover at the back of the air quality monitor.

2.Checking the correct polarization, insert 2 x C, IEC LR14, 1.5V Alkaline batteries into the battery compartment of the outdoor transmitter and insert 2 x AA, LR06, 1.5V Alkaline batteries in the air quality monitor. Replace the cover.

3.When the batteries are inserted, all the segments of the LCD will light up briefly. The monitor will receive data signal from the outdoor transmitter in a few seconds.

4.Hold the SET key for 3 seconds to manually enter a time. (See manual settings.)

Note:

•The equivalent CO2 ppm will only be displayed after 30 minutes.

•The air quality sensor will take up to 5 days after inserting battery to condition itself for the room it is placed. If the unit is placed into another room, there might be a reconditioning time of several days as well.

•Insert the holder to the bottom of the outdoor transmitter for table standing or insert it to the back of the transmitter for wall mounting purpose.

•Set the air quality monitor in a dry and shaded interior and away from sources of interference, such as televisions or metal plates. The transmitter should be mounted protected from rain and direct sunlight.

INSTALLING AND REPLACING THE BATTERY IN THE AIR QUALITY MONITOR

The outdoor transmitter uses 2 x AA, LR06, 1.5V batteries. The air quality monitor uses 2 x C, LR14, 1.5V batteries.

To install and replace the batteries, please follow the steps below:

1.Remove the cover at the back of the air quality monitor or the outdoor transmitter. Remove the old batteries and wait 2 minutes before the next step.

2.Insert batteries observing the correct polarity (see marking).

3.Replace compartment cover.

BATTERY CHANGE:

It is recommended to replace the battery regularly to ensure optimum accuracy of the unit.

Add device to MOBILE-ALERTS system

(MOBILE ALERTS gateway needed, sold separately)

Open the app, dashboard is displayed. Tap "Add new sensor" and scan the QR code on the back of the WL 2000. Then set a name for the sensor. To set a name, select the transmitter and then tap on the left area of the pencil icon in the upper right.

•The minute will be flashing. Press the + key to set the minutes.

•Confirm with the SET key and enter the °C/°F temperature setting.

°C/°F TEMPERATURE UNIT SETTING

The default temperature reading is set to °C (degree Celsius). To select °F (degree Fahrenheit):

1.The “°C” will be flashing, use the + key to toggle between “°C” and “°F”.

2.Confirm with the SET key and exit the manual settings.

Max./ Min. for the indoor/outdoor temperature and humidity

Press “MIN/MAX” for displaying of max./min. of temperature and humidity.

AIR QUALITY ALERT SETTING

Press the ALERT button to activate the air quality alert. The air quality alert OFF icon indicates that the alert is set off. No air quality OFF icon indicates that the alert is set on.

Note:

The LED Alert blinks, if the air quality alert has been set to “ON” and the Equivalent CO2 ppm is higher than 1500ppm:

AIR QUALITY INDICATOR

The air quality indicator is located on the bottom of the LCD. It changes from GREEN to RED by according to the equivalent CO2 ppm value.

Equivalent CO2 ppm (parts per million) value*

Air quality indicator

Bar graph

* The air quality value shown, after sensor conditioning, may differ +/- 250 ppm.

Note:

A 9-level bar graph is used to indicate “GREEN” to “RED” air quality level in the surrounding environment:

Levels	Equivalent CO2 ppm
GREEN (level 1)	450	– 600ppm
Level 2	650	– 800ppm
Level 3	850	– 1000ppm
Level 4	1050 – 1200ppm
Level 5	1250 – 1500ppm
Level 6	1550 – 1800ppm
Level 7	1850 – 2100ppm
Level 8	2150 – 2400ppm
RED (level 9)	≥ 2450ppm

Troubleshooting

When no sensor readings are displayed in the app, check if the green LED on the gateway is permanently lit. If not, please check if:

-The gateway is properly connected to the power plug, the router and is turned on.

-Restart the station by removing the batteries for a minute and reinserting, to restart the device.

-Your phone is connected to the internet.

-The signal is weakened by thick walls and ceilings. Put the device in operation near the gateway and then locate a suitable location.
