3.4.3 Display Console Set Up
Place the remote thermo-hygrometer about 5 to 10 feet away from the display console (if the sensor is too close, it may not be received by the display console).
1. Insert the power adapter into the power jack of the console, and plug in the adapter. The LCD
display will beep once and then light up. The brightness selection is set to high when plugged into the adapter.
2. Remove the battery door on the back of the display. Insert three AAA (alkaline or lithium,
avoid rechargeable) batteries in the back of the display console. Looking at the back of the unit (left to right), the polarity is (+) (-) for the top battery, (-) (+) for the middle battery and (+) (-) for the bottom battery.
Note: To avoid permanent damage, please take note of the battery polarity before
inserting the batteries.
3. Replace the battery door, and fold out the desk stand and place the console in the upright
position, as shown in Figure 5.
Note: The batteries are intended for back-up power only. The backlight will remain on
for 5 seconds when on back up battery power only. Only when you use power adapter it will the back-light be continuously on.
Version 1.0 Page 6
Receiver Model : WH2802

4. After initialization, the console will instantly display indoor temperature, humidity, barometer,
moon phase, date and time. The remote search icon will turn on：
Do not touch any buttons until the remote sensor reports in, otherwise the remote sensor search mode will be terminated and the search icon will turn off. When the remote sensor data has been received, the console will automatically switch to the normal mode, and all further settings can be performed.
3.4.4 Radio Controlled Clock (RCC)
Your console is equipped with the Radio Controlled Clock (RCC). The icon WWVB will appear above the time to signify this.
The RCC is received by the wireless transmitter, and passed to the console. After the remote sensor is powered up, the sensor will transmit weather data for 30 seconds, and then the sensor will begin radio controlled clock (RCC) reception.
During the RCC time reception period (maximum 10 minutes), no weather data will be transmitted to avoid interference.
If the signal reception is not successful (normally during the day due to solar interference), the sensor search will be cancelled, the outdoor temperature and humidity will update as normal, and the RCC search will automatically resume every two hours until the signal is successfully captured. The regular RF link will resume once RCC reception routine is finished. In some locations, RCC reception may take a couple of days to receive the signal. The temperature and humidity data will continue to transmit during this period.
Once the radio controlled time is received, the RCC reception icon will turn on (reference Figure 4).
3.5 Sensor Operation Verification
Verify the indoor and outdoor humidity match closely with the console and sensor array in the same location (about 10’ apart). The sensors should be within 10% worst case (the accuracy is ± 5%). Allow about 30 minutes for both sensors to stabilize.
Verify the indoor and outdoor temperature match closely with the console and sensor array in the same location (about 10’ apart). The sensors should be within 4°F worst case (the accuracy is ± 2°F). Allow about 30 minutes for both sensors to stabilize.

3.6 Sensor Placement
It is recommended you mount the remote sensor outside on a north facing wall, in a shaded area, at a height at or above the receiver. If a north facing wall is not possible, choose a shaded area, under an eve.
Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the sensor is weatherproof, it is best to mount in a well-protected area, such as an eve.
1. Use a screw or nail to affix the remote sensor to the wall, as shown in Figure 6.
2. Hang the remote sensor up on string, as shown in Figure 7.
Note: Make sure the sensor is mounted vertically and not lying down on a flat surface. This
will insure optimum reception. Wireless signals are impacted by distance, interference (other weather stations, wireless phones, wireless routers, TVs and computer monitors), and transmission barriers, such as walls. In general, wireless signals will not penetrate solid metal and earth (down a hill, for example).
3.7 Best Practices for Wireless Communication
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 console several feet away from computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 915 MHz devices and communication is intermittent, try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or receivers to avoid intermittent communication.
3. Line of Sight Rating. This device is rated at 300feet line of sight (no interference, barriers or walls) but typically you will get 100feet maximum under most real-world installations, which include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum siding. If

4.2 Barometric Pressure
4.2.1 Barometric Pressure History
While in normal mode, press BARO/- to check the barometric pressure history. Press the BARO/- button to switch to past 12hr/24hr/48hr/72hr average pressure. To exit the barometric pressure history mode, press the SNOOZE/LIGHT key (on the top of the display console), or wait 30 seconds for the timeout to take effect.
4.2.2 Relative vs. Absolute Pressure
While in normal mode, Press and hold the BARO/- button for 2 seconds to switch between
Version 1.0 Page 11
Figure 9

absolute (ABS) pressure and relative (REL) pressure.
Note: The display console displays two different pressures: absolute (measured) and relative
(corrected to sea-level).
To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at if located at sea-level) is generally higher than your measured pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level pressure around the world. Relative pressure measurements greater than 29.92 inHg (1013 mb) are considered high pressure and relative pressure measurements less than 29.92 inHg are considered low pressure.
To determine the relative pressure for your location, locate an official reporting station near you (the internet is the best source for real time barometer conditions, such as Weather.com or Wunderground.com), and set your weather station to match the official reporting station.
To calibrate the relative pressure to a local airport, please reference Section 4.5.
4.3 Dew Point
While in normal mode, Press the TEMP/+ key to view the Dew Point in the outdoor temperature field. If key idle 30 seconds, the display will return to normal mode.
To exit the Dew Point display mode, press the SNOOZE/LIGHT key (on the top of the display console), or wait 30 seconds for the timeout to take effect.

4.7.3 Weather Forecasting Description and Limitations
In general, if the rate of change of pressure increases, the weather is generally improving (sunny to partly cloudy). If the rate of change of pressure decreases, the weather is generally degrading (cloudy, rainy or stormy). If the rate of change is relatively steady, it will read partly cloudy.
The reason the current conditions do not match the forecast icon is because the forecast is a prediction 24-48 hours in advance. In most locations, this prediction is only 70% accurate and it is a good idea to consult the National Weather Service for more accurate weather forecasts. In some locations, this prediction may be less or more accurate. However, it is still an interesting educational tool for learning why the weather changes.
The National Weather Service (and other weather services such as Accuweather and The Weather Channel) have many tools at their disposal to predict weather conditions, including weather radar, weather models, and detailed mapping of ground conditions.

5 Glossary of Terms
Term
Definition
Accuracy
Accuracy is defined as the ability of a measurement to match the actual value of the quantity being measured.
Hygrometer
A hygrometer is a device that measures relative humidity. Relative humidity is a term used to describe the amount or percentage of water vapor that exists in air.
Range
Range is defined as the amount or extent a value can be measured.
Resolution
Resolution is defined as the number of significant digits (decimal places) to which a value is being reliably measured.
Absolute Barometric Pressure
Relative barometric pressure, corrected to sea-level. To compare pressure conditions from one location to another, meteorologists correct pressure to sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at if located at sea-level) is generally higher than your measured pressure.
Relative Barometric Pressure
Measured barometric pressure relative to your location or ambient conditions.
HectoPascals (hPa)
Pressure units in SI (international system) units of measurement. Same as millibars (1 hPa = 1 mbar)
Inches of Mercury (inHg)
Pressure in Imperial units of measure. 1 inch of mercury = 33.86 millibars

7 Troubleshooting Guide
Version 1.0 Page 19
Receiver Model : WH2802
Problem
Solution
Make sure the remote sensor LCD display is working on both the console and the remote sensor.
Install a fresh set of batteries in the remote thermo-hygrometer. For cold weather environments, install lithium batteries.
Make sure the remote sensors are not transmitting through solid metal (acts as an RF shield), or earth barrier (down a hill).
Move the display console around electrical noise generating devices, such as computers, TVs and other wireless transmitters or receivers.
Move the remote sensor to a higher location. Move the remote sensor to a closer location.
Temperature sensor reads too high in the day time.
Make sure the thermo-hygrometer is mounted in a shaded area. The pre preferred location is a north facing wall because it is in the shade most of the day.
Indoor and Outdoor Temperature do not agree
Allow up to one hour for the sensors to stabilize due to signal filtering. The indoor and outdoor temperature sensors should agree within 3.6 °F (the sensor accuracy is ± 1.8 °F).
Use the calibration feature to match the indoor and outdoor temperature to a known source.
