FCC ID: MG3-H24428 Temperature and Humidity Sensor

Zigbee 3.0 Temperature and Humidity Sensor H24428 (THZB1) SPECIFICATIONS Frequency: 2.4GHz Zigbee (IEEE 802.15.4) Battery Type: CR2477 Battery Operating Temperature: -10C to 50C Operating Humidity: 0 % to 100 % non-condensing Dimension: 56 mm x 16.7 mm Battery Life: 3 Years Temperature Reporting: 0C to 50C ( 0.5) Humidity Reporting: 20 % to 80 % ( 2) Ingress Protection: IP20 PAIRING SENSOR This Temperature and Humidity sensor needs to be paired before installation. 1. Pull the exposed plastic tab from the sensor. (Figure 1) 2. 3. 4. The LED indicator will be blink three times in green color to indicate a successful booting. (Figure 2) The LED will blink three times every 2-3 seconds in amber color while scanning the Zigbee network. If network is found and successfully joined, the LED will be lit for 1 second in amber color followed by a short blink in green color. If network is not found after 3 minutes, the sensor will go into sleep mode and the LED will blink in amber color every 1 minute. You need to reset the sensor to trigger a pairing process, and then sensor will repeat steps from 2 to 4. 5. Note: MAC address of the Sensor can be found on the QR code by scanning it with your mobile phone. Reset to Factory Defaults & Reboot 1. Remove from the rear cover if it has been assembled. 2. Remove the battery for at least 5 seconds. 3. Press and hold down button while re-inserting the battery. (Figure 2) 4. Release the button within 3 seconds after insert the battery. Mounting bracket Battery Tab Figure 1 LED Indicator Button Figure 2 INSTALLATION 1. Use the provided double-sided tape on the mounting bracket. (Figure 1) 2. Tear off the protective film of the double-sided tape. 3. Attach the sensor to the desired area. Press firmly and hold in place for a few seconds (Figure 3).

* Keep the surface clean and dry before attach the sensor.

* Do not install on the metal surface, it will affect the wireless communication range. Figure 3 OPERATION The LED will blink every 5 minutes in green color to indicate the sensor is working properly. MAINTENANCE REPLACE THE BATTERY When the battery is low, a signal will be sent to the control panel. The LED will blink every 2 minutes in red. To insert or replace the battery:

1. Rotate the sensor in counterclockwise and detach it from the mounting bracket. (Figure 4) 2. Remove the battery. (Figure 5) 3. Press and hold the button for 5 seconds, then release the button. 4. 5. Fit the sensor on the mounting bracket, rotate and lock in position. (Figure 6) Insert a new CR2477. Figure 4 Figure 5 Figure 6 WARNING: Failure to follow these warnings and instructions can lead to heat generation, rupture, leakage, explosion, fire, or other injury, or damage. Do not insert the battery into the compartment in the wrong direction. Always replace the battery with the same or equivalent type (see Specifications on section 1). Never recharge or disassemble the battery. Never place the battery in fire or water. Always keep batteries away from small children. If batteries are swallowed, promptly see a doctor. Always dispose and/or recycle used batteries in accordance with the hazardous waste recovery and recycling regulations for your location.
