1Introduction
Thank you for your purchase of the Ambient Weather WS-09 8-Channel Wireless Refrigerator/Freezer
Thermometer. The following user guide provides step by step instructions for installation, operation
and troubleshooting. To download the latest manual and additional troubleshooting tips, please visit:
http://ambientweather.wikispaces.com/ws09
The probe thermometer allows you to measure the temperature inside a refrigerator or freezer, while
mounting the display on the outside of the refrigerator/freezer.
Wireless signals cannot pass through a metal barrier. If your refrigerator/freezer is constructed of
metal, the probe will have to be placed inside the refrigerator/freezer and the display/transmitter
outside the refrigerator/freezer.
In addition to the refrigerator/freezer application, the probe thermometer can be placed in any medium
where temperature is required, including ground temperature, air temperature and water temperature.
2Getting Started
Note: The power up sequence must be performed in the order shown in this section (insert
batteries in the remote transmitter(s) first, Display Console second).
The WS-09 weather station consists of a display console (receiver), and two probe thermometers for
the refrigerator/freezer.

8. Close the battery door. Make sure the gasket (around the battery compartment) is properly
seated in its trace prior to closing the door. Tighten the set screw.
2.2 Display Console Set Up
1. Move the remote probe thermometer(s) about 5 to 10’ away from the display console (if the
sensor is too close, it may not be received by the display console). If you have more than one
probe thermometer, make sure they are all powered up and transmitting on different channels.
2. Remove the battery door on the back of the display, as shown in Figure 4. Insert four AAA

(alkaline or lithium, avoid rechargeable) batteries in the back of the display console.
Figure 4
All of the LCD segments will light up for a few seconds to verify all segments are operating properly.
3. 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 as designated by the icon. The
remote temperature probes will update on the display within a few minutes on the
appropriate channel.
While in the search mode, the remote search icon will be constantly displayed for each
sensor.
If you have more than two remote sensors (additional channels 3-8 are supported), the
display will automatically toggle between sensors until all sensors have reported in.
Do not touch any buttons until all of the remote sensors has reported in, or the radio search
icon is no longer visible, otherwise the remote sensor search mode will be terminated.
When the remote sensor temperature has been received, the console will automatically
switch to the normal mode, and all further settings can be performed.
If a remote does not update, please reference the troubleshooting guide in Section 7.

2.2.2 Sensor Operation Verification
Verify the temperature sensors match closely with the console and sensor array in the same location
(about 5 to 10’ apart). The sensors should be within 2°F (the accuracy is ± 1°F). Allow about 30
minutes for both sensors to stabilize. The temperature can be adjusted or calibrated later to match each
other or a known source.
3Remote Sensor Installation
The remote probe sensors have many applications, including measuring inside/outside air temperature,
water temperature, soil or ground temperature and refrigerator / freezer temperatures.

Version 1.0 ©Copyright 2013, Ambient LLC. All Rights Reserved. Page 7
3.1Refrigerator/Freezer Mounting
Each sensor includes a detachable suction cup that may be used to secure the remote sensor to the
interior or exterior surface of the refrigerator/freezer, as shown in Figure 6.
For better reception, we recommended installing the sensor to the outside of the refrigerator/freezer. If
the refrigerator/freezer is a metal box, the wireless signal cannot escape, and the sensors must be
placed on the outside.
Figure 6
To attach the suction cup to the remote sensor, reference Figure 7.
1. Locate the mounting hole on the back of the unit.
2. Press the suction cup into the mounting hole.
3. While applying pressure with your thumb, twist the suction cup until fully inserted.
4. Wet the back of the suction cup and apply to clean, smooth, flat surface.

Figure 7
Note: Both sensors have the capability of being placed inside or outside the
refrigerator/freezer, but it is recommended you install it outside. This will extend the battery life,
the sensor life, and improve wireless communication range.
Note: Make sure that the refrigerator surface is smooth and clean, so that suction cups will
not fall off. It is recommended to wet the surface of the suction cup first to improve the seal.
3.2 Wall Mounting
The remote sensor can be mounted to a wall or horizontal surface to measure any temperature medium,
including air, water and soil.
Use a screw or nail (not included) to affix the remote sensor to the wall, as shown in Figure 8.
Note: If measuring outside air temperature, we recommend mounting the sensor in the shade, on
the north side of the house or structure to avoid radiant heat transfer.
