Notice!
1. Device must be wall-mounted vertically. Do not lay it flat
or upside down while working.
2. Do not mounted it in a wind gap, or cover its bottom,
which may affect the detected data.
Step 1: Separate Panel and Bottom case by removing the screw at the bottom of device. Insert all
wires into the right terminals and tighten screws. The wiring diagram is shown above.
Pay attention to the current direction of positive and negative, otherwise device will easily be burn!
Step 2:Mount the Bottom case onto wall with two screws (M4*25mm).The hole pitch 60mm is for
86/60mm box, and 82mm is for American 120mm box.
Step 3: Mount the Panel back by aligning its tabs and card slot onto the Bottom case.
Step 4: Tighten the fastening screw and the device is ready for normal work.

Operation
Local time setting
In normal display interface, long press K1 will enter the local time modification interface.
“Week” starts flashing, press K2 can switch among “MON-TUE-WED-THU-FRI-SAT-SUN”.
Choose one then press K1 will save the setting.
“Hour” starts flashing. Press K2, the value will cycle switchover from 00-23. Press K1 to save
the change.
“Minute” starts flashing. Press K2, the value will cycle switchover from 00-59. Then press K1
can save settings and return to normal display.
In the process of modification, long press K1 can save and return to the normal interface, long press
K2 can continuously increase the value.
VOC detection (optional)
Device has built-in a VOC sensor, and four levels can be detected and shown on the display:
Excellent, Good, Average & Poor. (VOC toxic gases include carbon monoxide, alcohol, hydrogen,
methane, isobutene, ammonia and benzene, etc.)
Calibration
Long press K1 and K2 buttons at the same time to enter in to the Calibration Setting interface,
then enter the password 1234 to access. Press K1 button to switch, press K2 button to adjust the value;
when finish the setting, press K1 button to exit or wait for 5s without any operations, it will return to
the normal working interface automatically.
Following is the information of each parameter:
Item Parameter Range Default Value
01 Temperature Calibration -5℃~+5℃00℃
02 Humidity Calibration -9%RH~+9%RH 00
03 CO2 Calibration -99~+99 00
Z-Wave Operation
Including& Excluding of Z-Wave network
Activate Inclusion/Exclusion mode in the gateway. When device is powered on, long press K2
can enter interface for inclusion or exclusion of Z-Wave network.
If device has not been included into any Z-Wave network before, “- - -”will display on the
screen.
Then press K2 once, “- - -” flashing and device enters into learning mode to get a node ID. If
inclusion is success, a node ID will display on the screen. If not, “- - -” will stop flashing in 20
sec.
If a node ID displays, it means the device is already in a Z-Wave network. To press K2 once can
remove it from the network. “- - -” displays and press K1 once can return to normal work.

Association Group
Device supports 2 association groups:
Group 1 is for “Notification” purpose, which can add up to 5 Node ID. Device works in “Push”
mode in “Notification Command Class”. Use “Configuration “can set the threshold of CO2
Notification report.
When detected value is more than setting value, device will send (CO2 Detected Event) report to
the Group 1. And this report will keep sending in every 30 sec unless the detected value lower
than setting value.
Use “Notification Set” can set this unsolicited report; this function is default as “OFF”.
A gateway is suggested to associate with Group 2, which can support only one Node ID. The
gateway can ask for detected data any time. And the device will report to this associated device
(gateway) when detected data changes:
CO2: report when any change ≥50ppm“Multilevel sensor Report (CO2=0x11)”
Temperature: report when any change≥ 0.5 “Multilevel sensor Report℃(Temp=0x01)”
Humidity: report when any change≥ 2%“Multilevel sensor Report (Humidity=0x05)’
Configuration Command Class
Command Class supported by the device:
