• Coin battery CR2477 - installed
• Double-sided adhesive disc
• Installation Manual
5. Installing the Wireless Temperature and Humidity Sensor
We recommend commissioning the Wireless Temperature and Humidity Sensor
to your wireless interface before afxing it to the wall.
Please visit kumocloud.com/resources for the kumo cloudTM installation manual for
details regarding commissioning this wireless sensor and return to this guide for
installing in your desired location.
• Remove the wireless sensor and double-sided adhesive strip from packaging.
• To activate your wireless sensor, pull the insulator tab completely out and it will
power on the sensor.
• Peel away one side of the adhesive strip and apply it to the backside of the wireless
sensor, pressing rmly.
- The backside can be identied by the side with the FCC ID printed on it.
- The small hole on the front, should be facing the room. This hole should
remain unimpeded for sensing purposes.
• Find a location to install your wireless sensor. The device should be placed in an
area allowing it to monitor and sense the room. (Recommended placement is
within
10 ft of wireless interface or indoor unit, unobstructed)
- The wireless sensor will work best when placed in an open area of the room
allowing it to sense the greatest area without obstruction.
- Do not place the wireless sensor in direct sunlight, near vents or window
openings, or in enclosed areas such as drawers, cabinets, behind furniture
or curtains, drafts, radiators, replaces, or on exterior walls.
• Peel away the other side of the adhesive strip and press rmly to the wall or
surface to mount. Allow to remain undisturbed at least 24 hours to ensure it is
bonded securely to surface. Bond should be 100% after 72 hours from application.
Do not move once adhered.
- Ensure surface is clean and dry before adhering. Substrates are best
prepared by cleaning with 50:50 mixture of isopropyl alcohol and water.
- Rigid surfaces may require 2 or 3 times more pressure to ensure adhesion.
- Ideal application temperature range is 70°F to 100°F (21°C to 38°C).
