THERMO-HYGRO TRANSMITTER WITH 433MHZ
USED WITH THE WEATHER STATION
Congratulations on purchasing an additional Thermo-Hygro transmitter for used with the Weather Station. Please read
the following information to ensure that your transmitter works correctly together with your Weather Station set.
THERMO-HYGRO TRANSMITTER
SETTING UP:
1.
Firstly, open the battery cover to your Weather Station and checking the correct polarization, insert 3 x AA, IEC
LR6, 1.5V batteries into the battery compartment.
2.
Replace the cover and ensure that the batteries do not spring free from the contacts, otherwise start up problems
may occur.
3.
Slide open the battery cover of the transmitter as indicated above and insert 2 x AA, IEC LR6, 1.5V batteries into
the battery compartment and replace cover.
4.
After 1 minute, repeat step 3 to activate the second transmitter (providing that the outdoor temperature and
humidity readings have been received from the first transmitter, otherwise transmission reception problems may
occur).
5.
If you have purchased a third transmitter, then wait a further 1 minute after completing step4 followed by repeating
steps 3.
Your transmitter(s) is now fully operational with the Weather Station.
IMPORTANT NOTE:
•
By the time of inserting the batteries into the next transmitter, the outdoor temperature and humidity readings from
the previous transmitter should be received. Always ensure that the readings are received from one transmitter
before activating the next.
•
Each successful 433MHz transmission from the transmitter to the Weather station should take approximately thirty
seconds. If no temperature readings are received within a minute after inserting the batteries into the transmitter,
then reset all units (see
Resetting
below).
•
The Weather station allows sufficient time for setting up process. If setting up has taken more than 8 minutes, then
the start up problems may occur because the Weather station may not attempt to receive the 433MHz signal after
this period.
•
Transmitter need not to be activated in any set order, except that each transmitter temperature and humidity
readings before activating the next transmitter. Each transmission signal received by the Weather Station will be
indicated by the satellite transmission icon and a 1, 2 or 3 icons (i.e transmitter 1, 2 or 3) on the LCD (unless only 1
transmitter is used) The icons are located on the Weather station LCD in between the outdoor temperature and
humidity readings.
•
Always insert batteries into the Weather station first before the transmitters otherwise transmission problems will
occur .
433MHZ-EMPFANGSTEST:
In normal surroundings (for example, away from interfering sources such as TV sets), the outdoor temperature and
humidity readings from the transmitter can usually be received within 1 minute of setting up. Should this not be the case,
then check the following:
1.
The distance of all units should be at least 1.5 – 2.0 meters away from interfering sources such as computer
monitors or TV sets.
2.
Avoid placing the units onto or in the immediate proximity of metal doors and window frames or structures.
3.
Using other electrical products such as wireless headphones and speakers that operate on the same frequency
signal (433MHz) can prevent the transmission pick up.
4.
Neighbours using electrical items operating on the 433MHz signal can also cause interference. In most severe
cases, readings will only be received once all the other electrical items using 433MHz are switched off.
5.
Within thick concrete rooms such as basements and tower blocks, the signal is naturally weaker. Should this
happen, then place the Weather station closer to a window or point its front or back in the general direction of the
transmitters (avoid placing near metal frames and structures).
6.
Transmission may be affected by exposure to extreme temperature conditions. For example, if the weather has
been extremely cold (under -25ºC) for an extended period of time, then the 433MHz may be weakened. Please
bear this in mind when positioning the transmitter ( see
Maintenance
below).
RESETTING:
1.
Remove the batteries from all the transmitters and the Weather station.
2.
Wait at least 30 seconds and repeat the procedures specified in Setting up above. Always wait at least 30 seconds
before reinserting the batteries, otherwise start up problems may occur.
Note:
Remember when inserting, the Weather station and all the transmitters have to be reset and insert the
batteries into the Weather station first.
WALL MOUNTING THERMO-HYGRO TRANSMITTER:
Each transmitter is supplied with 2 wall mounting screws and plastic anchors. To wall mount simply:
1.
Secure the wall base onto a desired wall using the screws and plastic anchors.
2.
Insert the transmitter to the wall base.
Note:
Before permanently fixing the transmitter wall base, pace all units in the desired locations to check that the
outdoor temperature and humidity readings are receivable. In event that the signal is not received, relocate
the transmitters or move them slightly as this may help the signal reception.
REPLACING BATTERIES:
Batteries of all units should be replaced at least once a year to maintain the optimum accuracy. Ensure that the batteries
used are new of correct size.
Please help to preserve the environment and return used batteries to an authorized depot.
MAINTENANCE:
•
Avoid placing the transmitter(s) in are prone to vibrations and shocks as these may cause damage to the
transmitter(s).
•
Avoid areas where the transmitter(s) can be exposed to sudden changes in temperature, i.e. direct sunlight,
extreme cold and wet/moist conditions as this may lead to rapid changes which may reduce the accuracy of the
readings.
•
When cleaning the casing, use a soft damp cloth only. Do not use solvents or scouring agents and do not
submerge into water.
•
Immediately remove all low powered batteries to avoid leakage and damage to the products. Replace only with new
batteries of the recommended size.
•
Do not make any repairs to the unit. Please return to the original point of purchase for repair by a qualified
engineer. Opening and tampering with the units may invalidate its guarantee.
