2.4 Display Console Set Up
Note: To avoid permanent damage, please take note of the battery polarity before inserting the
batteries.
Move the remote thermo-hygrometer at least 10’ away from the display console (if the sensor is too
close, it may not be received by the display console).
Remove the battery door on the back of the display. Insert two AA (alkaline or lithium, avoid
rechargeable) batteries in the back of the display console.
All of the LCD segments will light up for a few seconds to verify all segments are operating properly.
Replace the battery door, and fold out the desk stand and place the console in the upright position.
The console will instantly display indoor temperature, date and time. The outdoor temperature and
humidity will display --, then update on the display within a few minutes. Do not touch any buttons
until the remote sensor reports in, otherwise the remote sensor search mode will be terminated, and
you must power down and power up the console again. When the remote sensor data has been
received, the console will automatically switch to the normal mode, and all further settings can be
performed.
If the remote does not update, please reference the troubleshooting guide in Section 7.
2.5 Sensor Operation Verification
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 (the accuracy is ± 2°F). Allow about 30
minutes for both sensors to stabilize.
3. Remote Sensor Installation
It is recommended you mount the remote sensor on a north facing wall, in a shaded area. Direct
sunlight and radiant heat sources will result in inaccurate temperature readings. Although the sensor is
water resistant, it is best to mount in a well protected area, such as an eve.

Version 1.0 ©Copyright 2010, Ambient LLC. All Rights Reserved. Page 4
Use 3 screws to affix the mounting bracket to the wall. Connect the remote sensor to the wall
bracket with a precision screwdriver.

to confirm the hour selection.
The minute will begin flashing. Press the CH/+ key to advance the minute. Press and hold the CH/+
key to advance rapidly. Press the SET key to confirm the hour selection.
4.2 Min/Max Mode
While in Normal Mode, press the MIN/MAX key to enter the minimum mode, and the MIN icon and
minimum records will be displayed at the bottom of the display. Press and hold the RESET key for
two seconds to reset the minimum values to the current values.
Press the MIN/MAX key to enter the maximum mode, and the MAX icon and maximum records will
be displayed. Press and hold the RESET key for two seconds or more to reset the maximum values to
the current values.

4.3 Multi-Channel Operation
The WS-0100 supports up to three WH-2C remote thermo-hygrometers (one is included). The
optional sensors can be purchased atAmbientWeather.com.
4.3.1 Sensor Initialization
Power up the sensors and console in the following order:
1. Power up the console. Do not touch any of the buttons, as described in Section 2.4.
2. Power up the first remote thermo-hygrometer as described in Section 2.5. Wait until the
sensor reports into the console.
3. Power up the second remote thermo-hygrometer as described in Section 2.5. Wait until the
sensor reports to the console. The first sensor will be designated as Channel 1 and the second
sensor will be designated as Channel 2.
4. Power up the third remote thermo-hygrometer as described in Section 2.5. Wait until the
sensor reports to the console. The third sensor will be designated as Channel 3. The display
will switch between each sensor until you exit the initialization state by pressing any button.
4.3.2 Sensor Accuracy Note
Verify the temperature values match closely with the console and sensor array in the same location
(about 10’ apart). The sensors should be within 4°F (the accuracy is ± 2°F).
Humidity is a particularly difficult parameter to measure. Verify the humidity values match closely
with the sensor array in the same location (about 10’ apart). The sensors should be within 10%
humidity (the accuracy is ± 5%).
Allow about 30 minutes for both sensors to stabilize.
4.3.3 Viewing the 3 Sensor Channels
To view the 3 sensor channels, select the CH/+ button. The minimum and maximum can be viewed
for each channel as specified in Section 4.2.
