FEATURES:

• Quartz clock

• 12/24h time display

• Indoor temperature display in °C/°F

• Indoor humidity display in %RH

• Outdoor temperature display in °C/°F

• Air quality sensor for monitoring of indoor air quality

• Display of CO2 equivalent values and quality indicator

• Air quality alarm per LED

• Low battery indicator

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 CO

• 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.

Note:

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

Levels Equivalent CO

GREEN (level 1) 450 – 600ppm
Level 2 650 – 800ppm
Level 3 850 – 1000ppm
Level 4 1050 – 1200ppm
Level 5 1250 – 1500ppm

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.
