SETTING UP:
Please follow these steps to ensure that your new Weather Station works correctly with the
temperature transmitter(s):
1.
First, insert the batteries into the Weather station (see “How to install and replace
batteries in the Weather station”below). Once the batteries are in place, all
segments of the LCD will light up briefly. Then the indoor temperature, humidity level
bar, and the time as 0:00 will be displayed. If the indoor temperature is not displayed
after a few seconds, remove the batteries and wait for at least 30 seconds before
reinserting them.
2.
Once the indoor data is displayed proceed to step 3 only if you have purchase
optional transmitter(s). If not, please proceed to step 6.
Remark: If no purchase of optional transmitter had been made, the high frequency
mode will still take place after the time, indoor temperature and humidity had been
displayed. This will take 82 seconds. If no transmitter has been detected, the high
frequency icon will not be displayed and no high frequency reception will occur
under normal condition. The Weather Station will then start receiving the DCF time
reception.
3.
If you have purchase optional transmitter(s), within 82 seconds of activating the
Weather station, place the batteries into the transmitter(s) (see “How to install and
replace batteries in the Thermo-Hygro outdoor transmitter“ below).
Note: Should the total time of inserting the batteries into the transmitters take longer
than 82 seconds from the time of inserting the batteries into the Weather
Station then temperature reception problems may occur. If the temperature
is not being received, then see Checking for 433 MHz receptions, before
resetting the units (see Resetting the Weather Station below).
4.
The Weather Station can take up to 2 optional remote transmitters. If you have
purchased additional transmitters, wait until the outdoor temperature has been
received from the one transmitter before activating the next transmitter. However,
ensure that you leave 10 seconds in between the reception of the last transmitter
and the set-up of the following transmitter. The Weather Station will number the
transmitters in the order of set-up, i.e. the first transmitter will have the temperature
and humidity displayed with the channel number 1 against it and so on.
5.
When all the transmitters are set up, there is a testing period, during which the
display switches quickly between all the received transmitters at random, according
to which random transmission it receives. The process stops automatically when
(1)
No keys are pressed after 82 seconds
(2)
All the data of two channels are received
(3)
Any key is pressed
6.
After the high frequency reception, the remote temperature and humidity have been
received and displayed on the Weather station, the DCF-77 time code reception is
automatically started. This takes typically between 3-5 minutes in good conditions.
This time period is an excellent opportunity to locate the transmitter(s) in suitable
location(s) outdoors. In order to ensure sufficient 433 MHz transmission however,
this should under good conditions be no more than 25 meters from where the
Weather Station will be finally positioned (see notes on “Positioning” and “433
MHz Reception”).
