MARBELLA – Wireless pool thermometer
• The pool sensor floats on the water surface and measures the tem-
perature in a water depth of about 110 mm. You can fix the pool sen-
sor by a cord. Pull the cord through the opening.
• Once the desired location is chosen, check whether the transmission
from the pool sensor to the base station is possible (transmission
range of up to 100m in open areas). Within solid walls, especially
ones with metal parts, the transmission range can be reduced con-
siderably.
• If necessary choose another position for the base station.
9. Additional transmitters (item no.: 30.3239.02) optionally available
• Beside the pool transmitter the base station is able to receive 2 addi-
tional transmitters for the control of indoor (e.g. children's room,
wine-cellar etc.) or outdoor climate
9.1 Elements of the transmitter (Fig. 5):
E 1: Temperature or humidity
E 2: Transmission symbol
E 3: Transmission signal light
E 4: Battery compartment
E 5: °F/°C button
E 6: 1 2 switch for channel selection
E 7: TX button
E 8: Battery symbol
E 9: Channel number
E 10: Wall mounting hole
9.2 Installation of the optional transmitters
1. Open the transmitter's battery compartment.
2. Select channel 1 with the switch.
3. Insert two new AA 1,5 V batteries, polarity as illustrated. The meas-
ured temperature and humidity in sequence and the channel number
1 appear on the display.

9.3 Reception of the transmitters at the base station
• If the reception is successful, the outdoor temperature and humidity
appear on the base station display, next to the corresponding chan-
nel number.
• You can also start the search for the transmitter manually. Choose
with the CHANNEL/SEARCH button the corresponding channel and
press und hold the CHANNEL/SEARCH button for three seconds.
Press the TX button in the transmitter's battery compartment. The
reception symbol of the transmitter flashes and the base station will
scan the outdoor values.
• Press the CHANNEL/SEARCH button on the base station to display
sequentially the desired transmitters. On the display appear the
indoor values or the selected transmitter.
• Press the CHANNEL/SEARCH button again after the last registered
channel and a circle symbol will appear. On the upper display the
values of the internal sensor and the installed transmitters are dis-
played in sequence. To deactivate the function press the CHANNEL/
SEARCH button again.
• With the + MAX/MIN button you can recall the highest and lowest
temperature and humidity values for the actual selected channel (in,
1, 2) (see 7.2.1).
9.4 Positioning and fixing of the optional transmitters
• The transmitter can be wall mounted (mounting hole at the back).
When placed outdoors, choose a shady and dry place for the trans-
mitter. Direct sunlight may trigger incorrect measurement and con-
tinuous humidity damages the electronic components needlessly.
10. Care and maintenance
• Clean the devices with a soft damp cloth. Do not use solvents or
scouring agents.
• Remove the batteries if you do not use the devices for a long period
of time.
• Store the devices in a dry place.

10.1 Battery replacement

• Change the base station batteries, when the battery symbol "in"
appears on the upper display.
