The transmission range of the Outdoor Thermo-hygro transmitter may be affected by the
ambient temperature. At cold temperatures the transmitting distance may be decreased. Please
bear this in mind when placing the transmitter.
To install the Thermo-hygro transmitter outside, choose a shady and dry place. Before
fixing the Thermo-hygro transmitter with the enclosed screws, wait for 30 minutes to see
if the receiver is able to scan the signal from this location. Obstacles (walls, windows,
trees) and interfering radio waves (PC, mobile phone, TV) can impede the reception or
limit the range (about 100 meters in open space) considerably. Should interference
occurred, choose another location for the Thermo-hygro Transmitter and/or the Weather
Station.
If the outdoor temperature and humidity data are not being received within 1 minute after setting
up (or the outdoor display show "--.-" in the outdoor section of the Intelligent Weather Station
after 3 failed attempts during normal operation). Please check the following points:
1. The distance of the Weather Station or transmitter should be at least 1.5 to 2 meters away
from any interfering sources such as computer monitors or TV sets.
2. Avoid positioning the Weather Station onto or in the immediate proximity of metal doors or
window frames.
3. Using other electrical products such as headphones or speakers operating on the same
signal frequency (433MHz) may prevent correct signal transmission and reception.
3. Neighbours using electrical devices operating on the 433MHz signal frequency can also
cause interference.
4. "Visibility" of weather station and transmitter (e.g. through a window) increases the range.
Note:
When the 433MHz signal is received, 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 accidentally then reset all units (see Setting up above) otherwise
transmission problems may occur.
If no reception is possible despite the observation of these factors, all system units have to be
reset (see Setting up).
POSITIONING THE WEATHER STATION:
The Weather Station has been designed to be hung on a wall or free standing.
For Free standing:
Pull out the easel on the back of the unit and place onto a flat surface.
To wall mount
Choose a sheltered place. Avoid direct rain and sunshine.
Before wall mounting, please check that the outdoor temperature and
humidity values can be received from the desired locations. To wall
mount:
1. Fix a screw (not supplied) into the desired wall, leaving the head
extended out the by about 5mm.
2. Fold the stand of the Weather Station by pushing inward and hang
it onto the screw. Remember to ensure that it locks into place
before releasing.
