1 Introduction Thank you for your purchase of the Weather Station WH117L with Temperature&Humidity, sensor WH2F. The following user guide provides step by step instructions for installation, operation and troubleshooting. Product Features Figure 1 No 1 2 3 Description Radio Controlled Clock with Perpetual Calendar Indoor Humidity and Temperature Outdoor Humidity and Temperature Version 2.
PAGE 3
Figure 2 2 Getting Started Note: The power up sequence must be performed in the order shown in this section (remote transmitter first, Display Console second) to avoid the console synchronization time out. The WH117L weather station consists of a display console (receiver), and a thermo-hygrometer (remote transmitter). 2.1 Parts List QTY 1 1 Item Display Console Frame Dimensions (LxWxH): 7.25 x 4 x 1.25 in LCD Dimensions (LxW): 4.25 x 2.

We recommend lithium batteries for cold weather climates, but alkaline batteries are sufficient for most climates. We do not recommend rechargeable batteries. They have lower voltages, do not operate well at wide temperature ranges, and do not last as long, resulting in poorer reception. Replace the battery door and set screw. Note that the temperature and humidity will be displayed on the LCD display.

2.4.1 Radio Controlled Clock (RCC) If your console is equipped with the Radio Controlled Clock (RCC), the icon WWVB will appear above the time. WWVB is the NIST time signal radio station near Fort Collins, Colorado. 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.

Figure 4 Note: Make sure the sensor is mounted vertically and not lying down on a flat surface. This will insure optimum reception. 3.2 Wireless Reception Considerations 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). The following is a table of reception loss vs.

units from Celsius to Fahrenheit. 10. Indoor Temperature Calibration (default is measured indoor temperature). Press the SET key to adjust the indoor temperature. Press the + key or MIN/MAX key to adjust the temperature up or down in 0.1 degC (0.18 degF) increments. To view the uncalibrated value, press the ALARM key while the temperature is flashing. Reference Section 4.2.5 Setting Calibrated Temperature for more details on this function. 11.

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.

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).

In the alarm mode, Press the + key or MIN/MAX key to change or scroll the alarm value. Hold the + key or MIN/MAX key for 3 seconds to change the number rapidly. Press the ALARM key to select the alarm on or off (if alarm is enabled, the speaker icon on the LCD will be turned on indicating the alarm function has been enabled). Press the SET key to confirm the setting and continue pressing the SET key to toggle through each alarm mode until it returns to the normal display mode.

individual basis. While in Normal Mode, press the MIN/MAX key to enter the maximum mode, and the MAX icon and maximum records will be displayed and begin flashing. Press MIN/MAX key again to enter the minimum mode, and the MIN icon and minimum records will be displayed and begin flashing. Press MIN/MAX key again to return the Normal Mode. In the maximum (or minimum) reading Mode, press the + key to display the specific maximum (or minimum) value you wish to reset.

4.5.3 Weather Icons Sunny Partly Cloudy Cloudy Rainy The four weather icons are Sunny, Partly Cloudy, Cloudy and Rainy. There are also two weather tendency indicators to show the air pressure tendency between the weather icons. 4.5.4 Weather tendency indicator The weather tendency arrow is located between the weather icons to show the air pressure tendency and provide a forecast based on increasing or decreasing air pressure.
PAGE 16
4.5.5 Storm threshold indicator The storm threshold (the negative rate of pressure change signifying a storm is expected) can be adjusted by the user from level 3 to level 9 (the default level 4 mbar/hour). When negative rate of change of pressure is exceeded for 3 hours, the storm warning indicator will be activated, and the clouds with rain icon and tendency arrows will flash for 3 hours indicating the storm warning feature has been activated. 4.5.

Accuracy Accuracy is defined as the ability of a measurement to match the actual value of the quantity being measured. Pressure units in SI (international system) units of measurement. Same as millibars (1 hPa = 1 mbar) 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. Pressure in Imperial units of measure. 1 inch of mercury = 33.

There are dashes (--) on the display console. will turn on. Wait several minutes for the remote sensor to report in, or the search icon to turn off. If the synchronization fails, reset the console by removing one battery from the display console, wait 10 seconds, and reinsert the battery. Do not press any buttons while in the search mode. Temperature sensor reads too high in the day time.

The forecast icon is not accurate Display console contrast is weak Console beeps and resets to an official local weather station (reference Section 4.2.1) 3. The barometer is only accurate to ± 0.08 inHg within the following relative pressure range: 27.13 to 32.50 inHg, which corresponds to an altitude of -2,200 to 2,700 feet. At higher altitudes, expect some non-linearity or error. The weather station console must run for several days to trend barometric pressure.
