 3 options of recommended actions: ‘Open window’, ‘Close window’, no action.
 Depending on the comfort level and the ambient change conditions, the ‘Open window’ and ‘Close
window’ icons will be shown according to the table below:

ABOUT THE THERMO-HYGRO TRANSMITTER
The temperature may affect the range of the thermo-hygro transmitter. At cold temperatures the
transmitting distance may be decreased. Please bear this in mind when positioning the transmitter. Also
the batteries may be reduced in power for the thermo-hygro transmitter.
CHECKING FOR 915MHz RECEPTION
If the outdoor temperature and humidity data are not received within 3 minutes after set up (or
OUTDOOR display always shows “- -” during normal operation), please check the following points:
1.
The distance of the weather station or transmitter should be at least 5 to 6.5 feet (1.5 -2 meters)
away from any interfering sources such as computer monitors or TV sets.
2. Avoid placing the transmitter onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the 915MHz-signal
frequency may prevent correct signal transmission or reception.
4. Neighbors using electrical devices operating on the 915MHz-signal frequency can also cause
interference.
Note: When the 915MHz signal is received correctly, do not re-open the battery cover of either the
transmitter or weather station, as the batteries may spring free from the contacts and force a false reset.
Should this happen reset all units (see “Set up” above) otherwise transmission problems may occur.
The transmission range is around 330 feet (100 meters) from the thermo-hygro transmitter to the
weather station (in open space). However, this depends on the surrounding environment and
interference levels. If no reception is possible despite the observation of these factors, all system units
have to be reset (see “Set up” above).
