note:

Due to poor or non-performance of normal Alkaline batteries at temperatures around or below 0°C, the use of standard Alkaline batteries is not recommended for the outdoor unit. For the outdoor units, we, therefore, recommend installing Lithium batteries which are designed to function within a temperature range of -20°C to 60°C. These batteries are available through the Alecto service department on telephone number 073 6411 355 (Netherlands) or 03 238 5666 (Belgium) or via the internet www.alecto.nl.

The battery life of Lithium batteries with a capacity of 900 mAh is more than a year.

4. INSTALLATION

4.1 Indoor unit:

General installation and placement tips:

• Ensure that the ambient temperature around the indoor unit is not affected by lamps, radiators, doors or windows, drafts, etc..
• For hanging use: hang the unit free from obstructions, i.e. not behind a curtain, for example.
• Make sure that the adapter cable cannot lead to falls or tripping. Secure the cable with cable ties if it is too long.

Power supply:

The main power of the indoor unit is provided by the supplied power adapter. Insert the low voltage plug of the adapter into the DC5.0V connection on the right side of the indoor unit and connect the adapter to a 230V socket.

As a backup, to save the measurement data during a possible power failure or if the adapter is accidentally unplugged, 3 pcs 1,5V AAA batteries can be inserted. The light intensity setting will revert to the lowest setting after 5 seconds to increase battery life.

4

1. Open the battery compartment at the back of the indoor unit.
2. Insert the first battery and slide it all the way to the left.
3. Insert the second battery and slide it all the way to the right.
4. Insert the third battery in the middle between the first 2 batteries.
5. Finally, replace the battery cover.

Hang or stand:

The indoor unit can either be placed freestanding on a cabinet or desk (fold out the stand on the back of the indoor unit for this purpose) or the unit can be hung on the wall (see keyhole openings on the back).

4.2 Outdoor units:

General installation and placement tips:

• First, check that the outdoor units are within reach of the indoor unit before permanently mounting the outdoor units. Keep the distance between the outdoor units and the indoor unit to within 30 meters.
• Ensure that the outdoor units are placed at least 1,5 meters above the ground and freely exposed to the rain and wind.
• In order for the outdoor units to work as accurately as possible, they must stand as horizontal as possible. For the outdoor rain unit, check that the surface is level before mounting.
• To indicate which direction the wind is coming from, the outdoor wind unit must be oriented to the South. See the S designation at the bottom of the outdoor unit for this. Use the compass on the outdoor wind unit to correctly orientate the unit.

• Make sure the outdoor units hang and/or stand freely. The wind speed meter and the wind vane, in particular, should hang in direct wind.

• Find a location where the likelihood of blowing leaves is minimal. Leaves blown into the rain coop can block the rain gauge or affect the measurement results. In any event, we advise you to place the outdoor units in such a way that it is fairly easy to remove any leaves and to replace the batteries.
  • Perhaps the outdoor units can be located within reach for a week to try out all functions. Check that everything is functioning properly before placing the outdoor units in their permanent location.

4.3 Outdoor unit wind:

Registration:

First register the outdoor units with the indoor unit before permanent placement of the outdoor units Once the indoor unit batteries are installed, it will search for the outdoor units for the first 5 minutes. After the 5 minutes, the indoor unit can be manually set to receive. To do this, press the channel button for 2 seconds to set the indoor unit to receive mode.

Insert 4 x 1,5V AA batteries in the outdoor wind unit. See diagram. Set the Channel switch to the same channel selected on the indoor unit. Then press the TX key. Check that the indoor unit has received the signal. Press the TX button once more, if necessary. The outdoor temperature and humidity are displayed on the indoor unit via the outdoor wind unit.

7. GENERAL OPERATION AND FUNCTIONS:

7.1 Barometer:

The atmospheric pressure value is measured with a barometer. The atmospheric pressure value can be displayed in Ft, M, inHG, and hPa. In the Benelux, the hectoPascal notation is used; although previously air pressure was also expressed as 1 mbar equals 1 hPa. The atmospheric pressure decreases the higher you are above sea level. A rule of thumb is that the atmospheric pressure decreases by 1 hPa per 8 meters. In this weather station menu, the height can be entered so that the air pressure is compensated for and the correct air pressure value is displayed. The height can be adjusted in 10-meter increments between -90 meters and +1990 meters. See 6.4 for this setting.

7.2 Trend indication

Pressure Trend -12 -9 -6 -3 -0 +8 +4 +2 +6 -2 -4 -6 Hour Pressure 10.06 hPa

If the atmospheric pressure increases or decreases by 2 hPa per hour, the trend display will point up or down. If the air pressure changes less than 2 hPa per hour, the straight arrow will be displayed.

7.3 Weather forecast by icons:

The following icons indicate the respective weather forecast.:

8. MAINTENANCE

For easy access to the outdoor units to carry out minor maintenance or to replace the batteries, it is advisable to place the outdoor units in an accessible place, but still as far as possible in the wind or rain.

8.1 Rain meter:

The rain unit housing can be unclipped from the bottom center, and the inside of the rain gauge can then be cleaned. Use a soft long-bristle brush for this.

Clean the collection tray and remove any leaves. Place it back on the rain gauge (note the 2 protruding tabs on the back) and press the housing onto the rain gauge again until a mechanical "click" is heard. See also 4.4 cleaning.

8.2 Outdoor temperature and humidity sensor:

Blow the openings of the sensor housing clean and use a long-bristle soft brush to clean the rain slats. DO NOT use WATER but only a damp cloth.

8.3 Wind vane and windmill scoops:

Wipe these parts with a slightly damp cloth.

Check that the bearings still rotate smoothly at the same time.

9. USE INDOOR UNIT WITH BATTERIES.

The indoor unit also runs on batteries without an adapter. This will then run out faster than when using an adapter.

The display background will not illuminate, but when the buttons are pressed the background lighting will come on for 5 seconds. The light can then no longer be dimmed.

10. RECEPTION FUNCTION.

After installing the batteries and/or plugging in the power adapter connected to the mains, the indoor unit will begin receiving signals from the outdoor units for 5 minutes. The first to be received by the indoor unit will be seen as the correct outdoor unit and will remember the code of the outdoor unit. Check that it is the correct outdoor unit. After the 5 minutes, the indoor unit will stop receiving and will only display the value of the outdoor unit received during this process. To switch reception on again, press the channel key ☐ for at least 2 seconds. To turn off reception, press the channel key ☐ again for 2 seconds.
