ENVIRASTATION Weather Station Wireless Operation Instruction Manual
DWS-400
BEFORE YOU BEGIN
- IMPORTANT: Insert batteries into the home receiver unit first, then the remote sensor.
- Place the home unit as close as possible to the remote unit. This will help with synchronization between the remote sensor and the home unit.
- REMEMBER: Once you are ready to position your remote sensor and home unit, ensure that the distance is not outside the effective transmission range (100 feet). Some building materials and location of the home unit or remote sensor can affect transmission quality and range. Try various locations for best results.
BATTERY INSTALLATION
Home Receiver:
Lift off the battery cover on the back of the unit. Install 2 “AA” alkaline batteries included according to the polarity indicated. Close the battery cover.
Remote Sensor:
Remove the attached bracket stand. Loosen the 2 screws securing the battery cover with a small screwdriver and remove. Insert 2 “AA” alkaline batteries included according to the polarity direction indicated. Depress the C/F button to select either Centigrade or Fahrenheit temperature reading. Ensure the black gasket is properly seated in the housing and then replace the cover. Tighten the 2 screws to secure.
NOTE: There are no consumer serviceable parts.
(See Warranty section for contact information.)
GETTING STARTED
SETTING UP THE WIRELESS THERMOMETER
If you encounter any difficulties in setting up your wireless thermometer system, please contact Consumer Relations.
- For the first installation, always insert batteries into the home unit FIRST and then the remote sensor(s). (See BATTERY INSTALLATION section)
- Your new RF Thermometer is built with security code technology, the home unit will learn the code of the first remote sensor and log it in as channel 1. Channel 2 and Channel 3 will be registered in the same way if additional sensors are used. This unit can monitor up to 3 separate sensors.
- Once a channel is registered, it will not accept any new sensors. However, registered channels can be erased by removing the batteries in the remote sensor or the home unit.
- When replacing batteries for the remote sensor- Remember to clear the corresponding channel of the home unit by removing the batteries. –OR– Select the respective channel of the sensor by pressing the CHANNEL button. Hold the CHANNEL button for 3 seconds to clear the registration.
- Press the Tx button on the back of remote sensor to verify the RF reception.
- It is recommended to test the units next to each other to ensure that both the remote sensor and home receiver are properly synchronized.
NOTE: Keep the remote sensor out of direct sunlight and rain. Do not mount on metal surface.
SETTING UP THE BAROMETER
When powering up, the pressure/altitude display will show “Auto” and “Meter” for 60 seconds. It will automatically calculate and display the current altitude above sea level. Please compare the displayed altitude value (in meters) against the exact altitude you obtain from a local authority. Enter your value if the displayed value is not exactly correct.
To reset or recalibrate, please follow these steps:
- Hold “Pressure/Altitude” key for 3 seconds.
- Select Meter or Feet by pressing the “Pressure/Altitude” button. Press “HIST” to confirm.
- Press “Pressure/Altitude” and “ P/A- ” to enter the altitude value (-100 m to 2500 m).
- Press “HIST” to confirm and exit.
To select between mb/hPa and inHg, hold “ P/A- ” key for 3 seconds.
To view air pressure for the past 12 hours, press the “HIST” button to scroll through the hourly readings. The respective values can only be available after the barometer has recorded the pressure data in the past 12 hours. Push any other button to cancel the “view history” selection.
The spectrum bar chart indicates the pressure changes (range from -8 to +8 hPa mb) hourly over the past 12 hours.

WEATHER FORECAST WITH STORM ALERT
The built-in sensor will read the atmospheric pressure and calculate the weather conditions of the next 12 hours. These conditions will be displayed as; Sunny, Partial Sunny, Cloudy, Rainy, Stormy, Icy at the top of the LCD display.
LOW BATTERY INDICATION
Low battery indication is available for the home receiver and the remote sensor. Replace the batteries and follow the setup procedure as mentioned in this instruction manual.
MOUNTING INSTRUCTIONS
Both the Home Unit and Remote Sensor come with a table stand or they can be wall mounted.
Table Top –
For the home unit, simply attach the stand provided.For the remote sensor, simply fold out the attached stand from the mounting bracket.
Wall Mounting –
For the Home Unit – Remove the table top stand from the bottom of the unit. Fix a screw into the desired wall and place the home unit onto the screw using the back side hanging hole.
For the Remote Sensor – Fix two screws into the desired hanging location using the mounting bracket holes on the remote sensor as a template. Ensure that the screws are placed vertically (in a straight line up/down) along the surface and that there is proper distance between each screw to hang the mounting bracket. Align the hanging holes of the mounting bracket with the two screws and place unit onto the screws.
MAINTENANCE AND CARE INSTRUCTIONS
- Extreme temperatures, shock or areas of unusual vibration should be avoided to prevent damage to the units.
- Clean the units using only a soft, damp cloth to wipe. Do not use solvents, abrasives, detergents or other strong cleaning agents. After cleaning, wipe surfaces with a dry cloth.
- Do not submerge units in water or other liquids.
- Do not subject the units to extremely severe temperatures – DO NOT PLACE UNITS INTO OVENS, FREEZERS or MICROWAVE UNITS.
NOTE: Opening the housing (other than the battery compartment) of either the Remote Sensor or the Home Unit will invalidate your warranty. Do not attempt to repair this unit – There are no consumer serviceable parts.
TROUBLE SHOOTING
Indoor and Outdoor temperatures do not match when placed next to each other –
Each sensor is manufactured to be +/- 1 degree in accuracy under normal conditions. So it is possible to have up to two degrees difference shown on the separate temperature sensors (one could be “+1 degree” and the other “-1 degree”. Additionally, the calibration curve is different between the two units because of the greater temperature range of the outdoor sensor. Errors are usually noted on the extreme ends of the temperature ranges.
Base unit is not accepting remote transmissions –
The units may not be properly synchronized or the batteries may need to be replaced. See “SETTING UP THE WIRELESS THERMOMETER” section beginning on page 2 of the instructions for detailed instructions. With the two units next to each other, attempt synchronization. Remember to always place the remote sensor within the effective transmission range and away from large metal surfaces.
What is the recommended battery type?
Your units will come with 4 “AA” alkaline batteries (2 “AA” batteries required for each unit). We recommend using only alkaline batteries for replacements.
Where can I mount the remote sensor?
To get accurate readings and to prolong the life of your sensor, we recommend that you mount it out of direct sunlight and rain. Fog and mist will not affect the sensor, but large volumes of soaking rain may. To guard against this, we recommend that you mount it under the eve of your house, your garage or any other suitable place that will keep it out of direct sun and rain.
