The Outdoor Thermo-Hygro Transmitter
SETUP:
When one transmitter is used
1. First, insert the batteries into the transmitter (see “How

transmitter” below).
the batteries into the Temperature Station (see “How
to install and replace batteries in the Temperature
Station” below). Once the batteries are in place, all
segments of the LCD will light up briefly. The indoor
temperature and the time as 0:00 will then be
displayed. If they are not shown in LCD after 60
27
seconds, remove the batteries and wait for at least 60
seconds before reinserting them. Once the indoor data
is displayed, user may proceed to the next step.
3. After the batteries are inserted, the Temperature
Station will start receiving data signal from the
transmitter. The outdoor temperature and humidity
should then be displayed on the Temperature Station.
If this does not happen after 2 minutes, the batteries
will need to be removed from both units and the setup
restarted from step 1.
4. In order to ensure an optimal 868 MHz transmission, in
good conditions, the distance between the
Temperature Station and the transmitter should not be
no more than 100 meters (see notes on “Positioning”
and “868 MHz Reception”).
When more than one transmitter is used
1. User shall remove all the batteries from the Temperature
Station and the transmitter and wait 60 seconds (if setup
has been done with one transmitter before).
2. Insert the batteries into the first transmitter.
3. Within 2 minutes of powering up the first transmitter,
insert the batteries into the Temperature Station. Once
the batteries are in place, all segments of the LCD will
light up briefly. The indoor temperature and the tim e as
0:00 will then be displayed. If they are not shown in LCD
after 60 seconds, remove the batteries and wait for at
least 60 seconds before reinserting them.
28
4. The outdoor temperature and humidity from the first
transmitter (channel 1) should then be displayed on the
Temperature Station. Also, the signal reception icon will
be displayed. If this does not happen after 2 minutes, the
batteries will need to be removed from both units and
the setup restarted from step 1.
5. Insert the batteries to the second transmitter as soon as
the outdoor temperature and humidity readings from the
first transmitter are displayed on the Temperature
Station.
Note: User shall insert the batteries into the second
transmitter within 30 seconds of reception of the first
transmitter.
6. The outdoor temperature and humidity from the second
transmitter and the "channel 2" icon should then be
displayed on the Temperature Station. If this does not
happen after 2 minute, the batteries will need to be
removed from all the units and the setup restarted from
step 1.
7. Insert the batteries into the third transmitter as soon as
the "channel 2" icon and outdoor data are displa yed on
the Temperature Station. Within 2 minutes, the channel
3 outdoor data from the third transmitter will then be
displayed and the channel icon will shift back to "1" once
the third transmitter is successfully recognized. If this is
not happen, user shall restart the setup from step 1.
29
Note: User shall insert the batteries into the third transmitter
within 30 seconds of reception of the second transmitter.
8. In order to ensure an optimal 868 MHz tr ansmission, in
good conditions, the distance between the Temperatu re
Station and the transmitter should not be no more than
100 meters (see notes on “Positioning” and “868 MHz
Reception”).

HOW TO INSTALL AND REPLACE BATTERIES IN THE
THERMO-HYGRO TRANSMITTER
The Thermo-Hygro transmitter uses 2 x AA, IEC LR6, 1.5V
batteries. When batteries will need to be replaced, the low
battery icon will appear on the LCD of the Temperature
Station. To install and replace the batteries, please follow the
steps below:
Note:
In the event of changing batteries in any of the units,
need to be reset by following the setup procedures. A random
security code is assigned by the transmitter at start-up and this
code must be received and stored by the Temperature Station
within the first 3 minutes of power supplying.
1. Lift up the rain protector of the
transmitter and remove the battery
cover.
2. Insert the batteries, observing the
correct polarity (see marking).
3. Replace the rain protector and battery
cover on the unit.

BATTERY CHANGE:
It is recommended to replace the batteries in all units at least
every 24-month to ensure optimum accuracy of these units.

humidity data to the current value by following this step :
1. Press and hold the “min/max/+” key for about 3
seconds to reset all the minimum/ maximum data of all
channels and the indoor sensor to the current values in
a single action.
THERMO-HYGRO TRANSMITTER :
The outdoor temperature and humidity are measured and
transmitted every 4.5 seconds.
The range of the Thermo-Hygro transmitter may be affected by
the temperature : at cold temperatures, the transmitting
distance may be decreased. Please bear this in mind when
placing the transmitter.
868 MHz RECEPTION CHECK
The Temperature Station should receive the temperature and
humidity data within a few minutes after setup. If the
temperature and humidity data is not received 5 minutes after
setup (the display shows “- - -” after consecuti ve failures in
receiving signal), please check the following points :
1. The distance of the Temperature Station or transmitter
should be at least 1.5 to 2 meters away from any
interfering sources such as computer monitors or TV
sets.
37
2. Avoid positioning the Temperature Station onto or in the
immediate proximity of metal window frames.
3. Using other electrical products such as headphones or
speakers operating on the same signal frequency
(868MHz) may prevent correct signal transmission and
reception.
4. Neighbours using electrical devices operating on the
868MHz signal frequency can also cause interference.
Note:
When the 868MHz signal is received correctly, do not re-open
the battery cover of either the transmitter or Temperature
Station, as the batteries may spring free from the contacts and
force a false reset. Should this happen accidentally, reset all
units (see “Setup” above), otherwise transmission problems
may occur.
The transmission range is about 100 m from the transmitter to
the Temperature 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 “Setup”).
POSITIONING THE TEMPERATURE STATION :
The Temperature Station comes attached with a foldout table
stand, which provides the option of table standing or wall
mounting the unit. Before wall mounting, please check that th e
outdoor temperature and humidity values can be received from
the desired locations.
38
To attach to the wall, please follow the steps below :
1. Fix a s crew (not supplied) into the
desired wall, leaving the head
extended out by about 5mm.
2. Hang the Temperature Station onto
the screw. Remember to ensure
that it locks into place before
releasing.
POSITIONING THE THERMO-HYGRO TRANSMITTER
The Thermo-hygro transmitter is supplied with a holder that
may be attached to a wall with the two screws supplied. Bef ore
securing the transmitter, ensure that the 868MHz signal is
properly received. To attach to the wall, please follow the steps
below :
1. Mark the wall using a pen
through the holes in the
holder to obtain the exact
drilling position.
2. Drill holes in the wall at the
marked points.
3. Screw the holder onto wall.
39
User may also use the double sided tape to install the
transmitter onto the wall. On smooth surfaces this can be used
instead of drilling holes. However, the mounting surface can
affect the transmission range. If, for instance, the transmitter is
attached to a piece of metal, it may then either reduce or
increase the transmitting range. For this reason, we
recommend not to place the transmitter on any metal surfaces
or in any position where a large metal or highly polished
surface is in the immediate vicinity (garage doors, double
glazing, etc.). Before securing in place, please ensure that the
Temperature Station can receive the 868MHz signal from the
Thermo-hygro transmitter at the positions that you wish to
place them.

• Do not make any repair attempts to the unit. Return
them to their original point of purchase for repair by a
qualified engineer. Opening and tampering with the unit
may invalidate their guarantee.
• Do not expose the units to extreme and sudden
temperature changes, this may lead to rapid changes in
forecasts and readings and thereby reduce their
accuracy.
