The sensors should agree within 10% (the accuracy is ± 5%). Allow about 30 minutes for all sensors to stabilize. The humidity can be adjusted or calibrated later to match each other a known source. Verify the temperature sensors match closely with all of the sensors in the same location (about 5 to 10’ apart). The sensors should be within 4°F (the accuracy is ± 2°F). Allow about 30 minutes for all sensors to stabilize. The temperature can be adjusted or calibrated later to match each other or a known source. 3 Remote Sensor Installation If you mount one or more of the sensors outside, it is recommended you mount the sensor in a shaded area. Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the sensors are water resistant, it is best to mount in a well-protected area, such as under an eve. Use a screw to affix the remote sensor to the wall, as shown in Figure 6. Alternately, you can hang the sensor with fishing wire or a string. This insures the sensor does not come into contact with any radiant heat source.

Figure 13 Scroll to the temperature or humidity field you wish to calibrate, press the key to perform the calibration, and press the or key to match your calibration source.
Receiver Model : HP3002 Sensor Model : WH31E Version 1.0 Page 14 Figure 14 4.2.1 Notes about Calibration Note: The calibrated value can only be adjusted on the console. The remote sensor(s) always displays the un-calibrated or measured value. Note: The measured humidity range is between 10 and 99%. Humidity cannot be accurately measured outside of this range. Thus, the humidity cannot be calibrated below 10% or above 99%. The purpose of calibration is to fine tune or correct for any sensor error associated with the devices margin of error. The measurement can be adjusted from the console to calibrate to a known source. Calibration is only useful if you have a known calibrated source you can compare it against, and is optional. This section discusses practices, procedures and sources for sensor calibration to reduce manufacturing and degradation errors. Do not compare your readings obtained from sources such as the internet, radio, television or newspapers. They are in a different location and typically update once per hour. The purpose of your weather station is to measure conditions of your surroundings, which vary significantly from location to location. 4.2.2 Humidity Calibration Methods Official stations recalibrate or replace humidity sensors on a yearly basis. Due to manufacturing tolerances, the humidity is accurate to ± 5%. To improve this accuracy, the indoor and outdoor humidity can be calibrated using an accurate source, such as a sling psychrometer or one step humidpak calibration kits.
Receiver Model : HP3002 Sensor Model : WH31E Version 1.0 Page 15 4.2.3 Temperature Calibration Methods Temperature errors can occur when a sensor is placed too close to a heat source (such as a building structure, the ground or trees). To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal (dial) and other digital thermometers are not a good source and have their own margin of error. Using a local weather station in your area is also a poor source due to changes in location, timing (airport weather stations are only updated once per hour) and possible calibration errors (many official weather stations are not properly installed and calibrated). Place the sensor in a shaded, controlled environment next to the fluid thermometer, and allow the sensor to stabilize for 48 hours. Compare this temperature to the fluid thermometer and adjust the console to match the fluid thermometer. 4.3 Min / Max and Alarm Mode In the Normal mode, press the MENU key three times to enter Min / Max and Alarm Mode. 4.3.1 Min / Max Icon Description Scroll down/right key Press this key to scroll down/right. .

Receiver Model : HP3002 Sensor Model : WH31E Version 1.0 Page 22 Figure 22 5 Other Features 5.1 Radio Controlled Clock (RCC) 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 5 minutes), no weather data will be transmitted to avoid interference. If the signal reception is not successful within 3 minute, the signal search will be cancelled and 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. Once the radio controlled time is received, the RCC reception icon will turn on next to the date and time field. 5.2 SD Card Export and Firmware Updates With the use of an optional Micro SD Card, you can export data to a computer, save historical graphs (in the event of a power failure) and update firmware when new versions are released.

Do not lie 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 console several feet away from computer monitors and TVs. 2. Radio Frequency Interference (RFI). If you have other 433 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 300 feet line of sight (no interference, barriers or walls) but typically you will get 100 feet 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 you have metal siding, align the remote and console through a window to get a clear line 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.

Receiver Model : HP3002 Sensor Model : WH31E Version 1.0 Page 31 10 Troubleshooting Guide Problem Solution Wireless remote (thermo-hygrometer) not reporting in to console. There are dashes (--.-) on the display console, and these sensors are a port of your system. If any of the sensor communication is lost, dashes (--.-) will be displayed on the screen. To reacquire the signal, re-acquire the signal per Section 4.4.3. Please verify each sensor is on a different channel by viewing the sensor’s LCD display. The maximum line of sight communication range is 300’ and 100’ under most conditions. Move the sensor assembly closer to the display console. If the sensor assembly is too close (less than 5’), move the sensor assembly away from the display console. Make sure the remote sensor LCD display is working. 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 on the north facing wall. Temperature sensors do not agree Allow up to one hour for the sensors to stabilize due to signal filtering. The sensors should agree within 4 °F (the sensor accuracy is ± 2 °F) under worst case conditions. Use the calibration feature to match the indoor and outdoor temperature to a known source. Humidity sensors do not agree Allow up to one hour for the sensors to stabilize due to signal filtering. The indoor and outdoor humidity sensors should agree within 10 % (the sensor accuracy is ± 5 %) under worst case conditions. Use the calibration feature to match the indoor and outdoor humidity to a known source. Display console contrast is weak Check the backlight display settings referenced in Section Back Light.
