Frequently Asked Questions - WS-0270 Ambient Weather

What is the maximum transmission range of the WS-0270?

The maximum line of sight transmission range is 265 feet. Under typical conditions with walls and obstructions, expect around 100 feet.

What type of batteries should I use?

Use fresh alkaline batteries for temperatures down to -4°F, and lithium batteries for temperatures as low as -40°F. Avoid rechargeable batteries as they have lower voltage and shorter life.

How do I resynchronize the remote sensor if it loses connection?

If dashes (--.-) appear on the display, press both the °C/°F and High/Low Record buttons simultaneously for five seconds. The search icon will flash until the signal is reacquired.

What is the accuracy of the temperature readings?

Both indoor and outdoor temperature readings have an accuracy of ±1°F.

Can I use the WS-0270 indoors only?

The sensor is designed for outdoor use but is water-resistant. It is best mounted in a shaded area, such as under an eve. The console is for indoor use.

How do I change the temperature units from Fahrenheit to Celsius?

Simply press the °C/°F button on the left side of the console to toggle between units.

What does the High/Low Record button do?

It allows you to view and reset the high and low temperature and humidity records. Press to toggle between reset every 24 hours or never. To reset, remove and reinsert the console battery.

Why is my outdoor temperature reading too high during the day?

Ensure the sensor is mounted in a shaded area, preferably on a north-facing wall. Direct sunlight and radiant heat sources will cause inaccurate readings.

What is the indoor humidity range of the console?

The console measures indoor humidity from 1% to 99% with an accuracy of ±3% (guaranteed only between 20% and 90%).

How do I mount the remote sensor?

You can mount it using a zip tie through the integrated hanger for best accuracy, or with a nail or screw (cap diameter ≤5 mm) through the mounting hole.

1 Introduction

Thank you for your purchase of the Ambient Weather WS-0270 Wireless Indoor/Outdoor Thermometer with Indoor Humidity. 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.net/help

2 Getting 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-0270 weather station consists of a display console (receiver), and a thermometer (remote

transmitter).

2.3 Thermometer Sensor Set Up

Note: Do not use rechargeable batteries. They tend to have a lower operating voltage, do not have a wide temperature range, and do not last as long as non-rechargeable batteries.

We recommend fresh alkaline batteries for outdoor temperature ranges between -4^ and 140^ and fresh lithium batteries for outdoor temperature ranges between -40^ and 140^ .

1. Remove the battery door on the back of the sensor by sliding the compartment door down, as shown in Figure 1.

Figure 1

2 Wireless transmitter LED
3 AA Battery
4 Battery Compartment Cover

1. Insert one AA battery.
2. After inserting the battery, the remote sensor LED indicator will light for 4 seconds, and then flash once per 60 seconds thereafter. Each time it flashes, the sensor is transmitting data.
3. Close the battery door.

2.4 Display Console Set Up

1. Move the remote 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).

2. Remove the battery door on the back of the display, as shown in Figure 2. Insert one AA (alkaline or lithium, avoid rechargeable) battery 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.

1. 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 and humidity. The remote temperature will update on the display within a few minutes.

While in the search mode, the reception search icon .fish.

If the remote does not update, please reference the troubleshooting guide in Section 7.

2.4.2 Sensor Operation Verification

Verify the indoor and outdoor temperature 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.

3 Wireless Sensor Installation

It is recommended you mount the remote sensor 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 under an eve.

3.1 Mounting with Zip Tie

Mounting the sensor with a zip tie will result in better accuracy when mounting outside, since it is not touching another object. Other objects will store and radiate heat (or cold).

3.2 Mounting with Nail or Screw

To mount the sensor with a nail or screw, the cap must be less than or equal to 5.0 mm in diameter.

4 Console Operation

Note: The console has two buttons for easy operation: °C / °F button (on the left), and High / Low Record button (on the right).

4.1 Temperature Units of Measure

To change the temperature units of measure, press the C / ^ button (on the left).

4.2 High Low Record

The indoor temperature, indoor humidity, and outdoor temperature can be reset every 24 hours (based on when the batteries are inserted), or never.

Press the High / Low Record button (on the right) to switch between reset 24 hours or never.

To reset the highs and lows, remove and reinsert the battery inside the console. If Reset 24 hour option

is selected, the highs and lows will reset 24 hours after the battery is inserted.

4.3 Sensor Resynchronization

If the remote sensor is lost, dashes will be displayed. To resynchronize, press both the °C / °F and High / Low Record buttons at the same time for five seconds.

While in the search mode, the reception search icon _flash.

4.3.1 Best Practices for Wireless Communication

Note: To insure proper communication, mount the remote sensor on a vertical surface, such as a 1. Do not lay the sensor flat.

Wireless communication is susceptible to interference, distance, walls and metal barriers. We recommend the following best practices for trouble free wireless communication.

1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433 MHz devices and communication is intermittent, try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or receivers to avoid intermittent communication.
3. Line of Sight Rating. This device is rated at 300 feet line of sight (no interference, barriers or walls) but typically you will get 100 feet maximum under most real-world installations, which include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum siding. If you have metal siding, align the remote and console through a window to get a clear line of sight.

The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction decreases the transmission range by the factor shown below.

Medium	RF Signal Strength Reduction
Glass (untreated)	5-15%
Plastics	10-15%
Wood	10-40%
Brick	10-40%
Concrete	40-80%
Metal	90-100%
