Figure 5 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.

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.

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.

Page 13: Relative Pressure Calibration
4.2.2 Relative Pressure Calibration You will want to calculate your barometric pressure to an official reporting station in your area. Since barometric pressure does not drastically change in a 50 mile radius (unless the weather is rapidly changing), this method of calibration is acceptable. 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.

4.6 Calibration While in the normal node, press and hold the SET/CH and BARO/- keys for five seconds to enter calibration mode (note: the SET/CH mode will appear after three seconds. Continue pressing the two keys until you see the CAL icon appear in the upper right hand corner of the display). Enter the calibration offset to match the calibration source.
Page 16: Max/Min Mode
The calibrated absolute pressure from a calibrated pressure sensor, or actual absolute pressure is 28.61 inHg. The uncalibrated or measured absolute pressure measured by the weather station is 28.66 inHg. Offset = 28.66 – 28.61 = -0.05 inHg Enter the absolute pressure offset -0.05 inHg Note: The absolute pressure offset will also affect the relative pressure.

The forecast icon is based on the rate of change of barometric pressure. Please allow at least one month for the weather station to learn the barometric pressure over time.

4.8.7 Resynchronizing Lost Sensor If the signal is lost between the remote sensor (or transmitter) and the display console (or the receiver), to resynchronize, while in normal mode, Press and hold SET/CH and TEMP/+ button for 5 seconds, to register the outdoor transmitter. The sensor search icon will flash. Please wait several minutes for the remote sensor reports in.
Page 20: Glossary Of Terms
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.
Page 21: Measurement Specifications
6.2 Measurement Specifications The following table provides specifications for the measured parameters. Measurement Range Accuracy Resolution Indoor Temperature -14 to 140 °F ± 1.8 °F 0.1 °F -10 to 60 °C ± 1 °C 0.1 °C Outdoor Temperature -40 to 140 °F ±...

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).
