3 Getting Started

The WS-2801A weather station consists of a display console (receiver), thermos-hygrometer sensor and AC adapter.

Note: The power up sequence must be performed

in the order shown in this section (remote transmitter first, display console second) to properly synchronize the remote sensor to the console.

3.3 Thermo-Hygrometer Sensor Set Up

Remove the battery door on the back of the sensor, as shown in Figure 2.

1. BEFORE inserting the batteries, switch the

channel switch to the appropriate channel. If you have one sensor, set the switch to Channel 1. If you have two sensors, set the second sensor to Channel 2. If you own three sensors, set the third sensor to Channel 3.

2. To change the temperature units of measure,

press the ºC/ºF button.

3. Insert two AA batteries.

4. After inserting the batteries, the remote sensor

will display temperature and humidity and channel number on the display, as shown in Figure 3.

Measure

3 Channel Number 4 Humidity

5. Close the battery door.

Page 9

Note: 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.

Note: If the incorrect channel number is selected, change the channel number switch on the back of the sensor, and remove and reinsert the batteries for the change to take effect.

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. The brightness selection is set to high when plugged into the

Page 14

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.

4. After initialization, the console will instantly display

indoor temperature, humidity, barometer, moon

Page 15

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.

Page 16

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.

Page 17

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).
