3 Getting Started
The WH2812 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.

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.

5. Close the battery door.
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.

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.

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,
