Alecto WS-5500 Weather Station

INTRODUCTION

The Alecto WS-5500 weather station consists of the following components:

Outdoor unit:
The outdoor unit includes a built-in rain gauge, wind speed gauge, wind direction gauge, temperature sensor, humidity sensor, LUX meter and solar cell. The measurement data from the sensors is transmitted to the display unit. The outdoor unit is powered by a built-in super cap which in turn is powered by the built-in solar panel. You may also install lithium backup batteries, for this please see below in this user manual.
The outdoor unit comes including mounting materials.

Indoor unit:
The indoor unit receives the measured data from the outdoor unit and also includes its own temperature sensor, humidity sensor and pressure sensor. The indoor unit is powered through the supplied power adaptor, although you may also install 3x AAA 1.5 V backup batteries (not incl.). All measurement data is shown in the large 6.9” (17.5 cm) LCD colour screen. Additionally, you may forward these  measurements to websites such as ‘Wunderground’ to further publish them via the internet or to share the information with third parties.

MAINTENANCE

For easy access to the outdoor unit to perform small maintenance or to replace the batteries, it’s recommended to install the outdoor unit at an accessible spot. However, keep in mind to place it as open as possible in wind and rain.

Rain gauge:

You may unscrew the black rain collector tray by turning it counter-clockwise for cleaning the interior of the rain gauge. For this, please use a soft and long-haired brush. Clean the black collector tray and remove any leaves. Replace it onto the rain gauge (pay attention to the 3 protruding notches) and rotate the tray clockwise until you hear a ‘click’ coming from the mechanism.

Outdoor temperature and humidity sensor:

Refer to the picture and detach the lower 4 weather vanes from the outdoor unit. Blow into the holder containing the temperature and humidity sensor and use a soft brush with long hairs to clean the wind guides. DO NOT USE WATER. Replace and tighten the wind guides.

INSTALLATION

Indoor unit

General installation and positioning tips:

  • Make sure that the surrounding temperature at the indoor unit is not affected by lights, radiators, doors or windows, draft, etc.
  • When suspended: make sure the unit is freely suspended, i.e. not behind a curtain.
  • Make sure that the adaptor wire doesn’t create a falling or tripping risk. Use cable-ties when the wire is too long.

Power supply:

The main power of the indoor unit is provided through the supplied power adaptor. Insert the low-voltage plug of the adaptor into the DC5.0V input at the rear of the indoor unit and then connect the adaptor with a 230V wall socket.

You may install 3x 1.5V AAA batteries as a backup for maintaining the measured data in case of a possible power outage or for when the adaptor is disconnected from the wall socket by accident.
Power supply

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

Suspended or standing:

You may choose to use the indoor unit standing freely on a cabinet or desk (for this, fold out the 2 supports at the rear of the indoor unit) or suspended from a wall (see the suspension keyholes at the rear).

Outdoor unit:

General installation and positioning tips:

  • First check whether the outdoor unit is within range of the indoor unit before permanently installing the outdoor unit. Maintain a distance between the outdoor and indoor unit from 50 to 100 meters.
  • Make sure to place the outdoor unit at least 1.5 meters from the ground, positioned freely in the rain and wind.
  • To have the rain gauge function as accurate as possible, the outdoor unit must be placed exactly horizontal. For this you may use the built-in spirit level on top of the outdoor unit.
  • To be able to indicate from which direction the wind is blowing, the outdoor unit must be aimed to the North. For this, see the North indication on top of the outdoor unit. Use an accurate compass (not incl.) to properly orient the unit.
  • Make sure that the outdoor unit is suspended or standing freely. Especially the wind speed gauge and weather vane must be suspended directly into the wind.
  • Determine the location with the smallest chance of leaves blowing into the unit. Leaves blown into the rain collector can block the rain gauge and affect the measurement results. In any case, we recommend positioning the outdoor unit in such a way that any leaves blown into the unit can be easily removed and the 2 batteries of the outdoor unit can be easily replaced.
  • You may of course keep the outdoor unit within reach for the first week to try out all of its functions. After verifying that everything is working properly, you can then permanently install the outdoor unit.

Rain gauge:

The black rain collection tray must first be placed on the rain unit. There are three markings on the rain collection tray.
Position one of the markings approximately 3.5 cm in front of the markings on the rain unit. The whole bowl should now drop into the rain unit. Push in the scale slightly and turn it clockwise until it clicks into place, then, with some force, turn it further clockwise until it clicks into place. The mark on the scale is now directly above the mark on the rain unit.

Wind catcher:
Wind catcher

First check whether the small screw of the wind catcher is rotated outward far enough and then push the wind catcher over the axle on the outdoor unit. Adequately push in the wind catcher, but never force it!

Use a small cross-head screwdriver (excl.) to rotate the small screw and fix the wind catcher onto the axle.
Finally, blow against one of the wind catcher cups to check whether the wind catcher can rotate smoothly.

Wind direction:
Wind direction

Attention: Both the axle for the weather vane and the weather vane itself are flattened at one end. This ensures that the vane can slide over the axle in only one way. Please keep this in mind during the installation.

First check whether the small screw of the weather vane is rotated outward far enough and then push the vane over the axle on the outdoor unit. Pay attention to the flattened side!

Adequately push in the weather vane, but never force it!
Use a small cross-head screwdriver to rotate the small screw and fix the weather vane onto the axle.
Finally, blow against the side of the weather vane to check whether it can rotate smoothly.

Power supply:

The sensors in the outdoor unit are powered by a built-in ‘super cap’, which is a type or rechargeable battery.
This super cap is charged by the solar panel on top of the outdoor unit.
As a backup, in case the super cap is not properly charged, you must install 2 AA 1.5V batteries into the outdoor unit (not incl.).

Because regular Alkaline batteries perform poorly or not at all at temperatures around or below 0°C, we don’t recommend using standard Alkaline batteries for the outdoor unit.
Power supply

This is why we recommend inserting Lithium batteries into the outdoor unit, because these are developed for functioning within a temperature range of -20°C to 60°C.
These batteries can be ordered from the customer service department of Alecto via telephone number 073 6411 355 (Netherlands) or 03 238 5666 (Belgium) or via internet www.alecto.nl.
Lithium batteries with a capacity of 2900mAh have a life span of at least one year.

Positioning the outdoor unit:

Refer to the images below and fix the U-shaped cable ends to the outdoor unit, place the outdoor unit over the pole (not incl.) and fasten the nuts. Your weather station is now ready for use.
