NOTICE
Avoid connection faults!
In order to avoid connection problems between the devices, the following points must be observed during commissioning.

1. Place the base unit (receiver) and sensor (transmitter) as close together as possible.
2. Connect the power supply to the base unit and wait until the indoor temperature is displayed.
3. Establish power supply for the sensor.
4. Set up/operate the base unit and sensor within the effective transmission range.
5. Make sure that the base unit and the radio sensor are set to the same channel.

When changing the batteries, always remove the batteries from both the base unit and the sensor and reinsert them in the correct order so that the radio link can be re-established. If one of the two devices is operated via a mains power connection, the power connection must also be briefly disconnected for this device when the batteries are changed. If, for example, only the batteries in the sensor are replaced, the signal may subsequently not be received at all or not be received correctly.
Note that the actual range depends on the respective construction materials used for the buildings as well as the respective position of the base unit and the outdoor sensor. External influences (various radio transmitters and other sources of interference) can greatly reduce the possible range. In such cases, we recommend finding other locations for both the base unit and the outdoor sensor. Sometimes moving the sensor by just a few centimeters is enough! Though the remote unit is weather proof, it should be placed away from direct sunlight, rain or snow.

Setting up power supply

Base station

1. Remove the battery compartment cover.
2. Insert the batteries into the battery compartment. Ensure that the battery polarity (+/-) is correct.
3. Replace the battery compartment cover.
4. Wait until the indoor temperature is displayed on the base station.

Remote sensor

5. Remove the battery compartment cover.
6. Insert the batteries into the battery compartment. Ensure that the battery polarity (+/-) is correct.
7. Push the CH button to set the desired transmission channel (setting CH1, CH2 or CH3 on screen display).
8. Push the °C/°F button to set the desired temperature format (setting °C or °F on screen display).
9. Replace the battery compartment cover.

Automatic time setting

After the power has been restored, the unit automatically searches for the radio signal. It takes approximately 3-8 minutes for this process to be completed.
If the radio signal is received correctly, the date and time are set automatically and the reception symbol is displayed.
If no radio signal has been received, proceed as follows:

1. Press the UP button for approx. 2 seconds to initiate the reception of the radio signal again.
2. Press the UP button for approx. 2 seconds to initiate the reception of the radio signal again.
3. If still no radio signal is received, the time must be set manually.

Manual time setting

1. Press and hold SET button for approx. 2 seconds to change to time setting mode.
2. Digits to be set are flashing.
3. Press UP or DOWN button to change the value.
4. Press SET button to confirm and continue to the next setting.
5. Settings order: Year > Month > Day > Time zone > 12/24-hour mode > Hours > Minutes
6. Finally press the SET button to save the settings and exit the setting mode.

Time zone setting

If this weather station is to be used in an area where the UTC time standard is used (e.g. parts of the UK and Portugal), the time zone can be set manually to -1h UTC. To do this, follow the next steps.

1. Press and hold the SET button for about 2 seconds to switch to time setting mode.
2. The year digits flash.
3. Sequence of settings: Year > Month > Day >Time zone > 12/24 hour mode > Hours > Minutes.
4. Press the SET button until thetime zone setting flashes.
5. Press the DOWN button to change the value to -1.
6. Press the SET button repeatedly until the time setting mode is completed.

Alarm setting

1. Press Press ALARM button to show the alarm time.
2. Press and hold ALARM button for approx. 2 seconds to change to alarm time setting mode.
3. Digits to be set are flashing.
4. Press UP or DOWN button to change the value.
5. Press ALARM button to confirm and continue to the next setting.
6. Settings order: Hours > Minutes
7. Finally press the ALARM button to save the settings and exit the setting mode.
8. Press SET button to activate the alarm. Thesymbol will be displayed. The alarm is activated.
9. Press SET button again to disable the alarm. Thesymbol will not be displayed. The alarm is disabled.

Snooze function

1. When the alarm sounds, press SNZ button to activate the snooze function. The alarm will sound again in 5 minutes.
2. Press any other button when the alarm sounds to interrupt the alarm until the alarm time will be reached again.

Temperature alarm setting

1. In normal time display mode, press DOWN button for approx. 2 seconds to enter temperature alarm time setting mode.
2. Digits to be set are flashing.
3. Settings order: ON/OFF (Temperature alarm on/off) > Temperature highest limit > Temperature lowest limit > Exit
4. Press UP or DOWN button to change the value.
5. Press SET button to confirm and continue to the next setting.
6. The temperature settings mode will be quit automatically after 30 seconds of inactivity. All settings done before will be saved.
7. When outdoor temperature reaches highest or lowest limit, the temperature alarm symbol will flash and an alarm will sound for approx. 3 seonds. This will be repeated with an interval of 1 minute until the temperature has fallen below the limit again.

NOTICE! NOTICE! Select temperature alarm OFF from the temperature settings mode to disabled the temperature alarm permanently.

Receiving measurements automatically

Once batteries are installed, the base station will display the measurement readings. Readings from the remote sensor will be displayed within 3 minutes after powering it on.

Manual measurement display

1. Press UP button several times to display the saved values one after another.
2. Display order: Current values > MAX (highest values) > MIN (lowest values)
3. Press UP button for approx. 2 seconds during highest or lowest value display to irrevocable delete all saved values.

NOTICE! Saved highest and lowest values will be deleted automatically every day on 0:00!

Weather trend

The weather station will calculate a weather trend for the next 12 hours on basis of the measured values. It will be displayed as follows:

Connecting remote sensors

The measurements of up to 3 remote sensors* of the same type can be displayed on the weather station's screen.

1. Remove the battery compartment cover from the remote sensor.
2. Press the CH button repeatedly until the desired channel is shown on the sensor display (CH1, CH2 or CH3).
3. Re-attach the battery compartment cover.
4. Press the CH button on the base station repeatedly to display the measurements of the different channels. The selected channel is shown on the display.
5. Press CHANNEL button for about 3 seconds to reset the values and search for a wireless sensor (RF signal).

*one remote sensor included, more optionally available
