Remove the battery door on the back of the display. Insert one AA(alkaline or lithium, avoid rechargeable) battery in the back of the display console.All of the LCD segments will light up for a few seconds to verify all segments are operating properly.Figure 23. Replace the battery door, and fold out the desk stand and placethe console in the upright position.The console will instantly display indoor temperature and humidity.The remote temperature will update on the display within a few minutes.While in the search mode, the reception search icon flash.Note: If the remote does not update, please reference the troubleshooting guide in Section.2.4.1 Display Console Layout2.4.2 Sensor Operation VerificationVerify the indoor and outdoor temperature match closely with the console and sensor array in the same location (about 2 to 3m apart). The sensors should be within 2°C (the accuracy is ±1°C. Allow about 30 minutes for both sensors to stabilize.3. Wireless Sensor InstallationIt is recommended you mount the remote sensor in a shaded area. Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the sensor is water resistant, it is best to mount in a well-protected area, such as under an eve.3.1 Mounting with Zip TieMounting the sensor with a zip tie will result in better accuracy when mounting outside, since it is not touching other objects.Figure 43.2 Mounting with Nail or screwTo mount the sensor with a nail or screw, the cap must be less than or equal to 5mm in diameter.Figure 54.

Best Practices for Wireless CommunicationNote: To insure proper communication, mount the remote sensor on a vertical surface, such as a wall. Do not lay the sensor flat.Wireless communication is susceptible to interference, distance, walls and metal barriers. We recommend the following best practices for trouble free wireless communication.1. Electro-Magnetic Interference (EMI). Keep the consoleseveral feet away from computer monitors and TVs.2. Radio Frequency Interference (RFI). If you have other 433MHz devices and communication is intermittent, try turning offthese other devices for troubleshooting purposes. You mayneed to relocate the transmitters or receivers to avoidintermittent communication.3. Line of Sight Rating. This device is rated at 100meter line ofsight (no interference, barriers or walls) but typically you willget 30 meter maximum under most real-world installations,which include passing through barriers or walls.4. Metal Barriers. Radio frequency will not pass through metalbarriers such as aluminum siding. If you have metal siding,align the remote and console through a window to get a clearline of sight.The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction decreases the transmission range by the factor shown below.7.Specifications7.1.Wireless Specifications∙transmission range (in open air): 80meter∙Frequency: 433 MHz∙Update Rate:Indoor temperature/humidity 48 secondsOutdoor temperature CH1 48 secondsOutdoor temperature CH1 49secondsOutdoor temperature CH1 50 seconds7.2 Measurement SpecificationsThe following table provides specifications for the measured parameters.7.3Power Consumption∙Base station (display console) : 1 x AA 1.5V Alkaline or Lithium batteries (not included)∙Remote sensor : 1 x AA 1.5V Alkaline or Lithium batteries (not included)8.
