i Information about the atmospheric pressure

The weather station can display the atmospheric pressure in different ways, ABS absolute (actual pressure at current altitude) and REL relative (what the pressure would be at sea level).

• The relative value is used by meteorologists to be able to compare the atmospheric pressure at different locations.
• The normal atmospheric pressure at sea level varies depending on the geographical location but is usually approximately 1013.2 hPa. A pressure of under 990 hPa is regarded as low pressure and over 1020 hPa is regarded as high pressure.
• Since atmospheric pressure decreases with altitude, values for relative atmospheric pressures are generally higher than their absolute counterparts.

Sound settings for buttons and alarms

In normal mode, hold in [ HISTORY/- ] for 3 seconds to switch the sound on/off. BUZZON (On) or BUZZOFF (Off) will appear on the display respectively.

When the sound is switched off, no noise will be heard when buttons are pressed and any alarms emitted by the weather station will be silent (only the alarm symbols will flash).

Installation

Information

We recommend that you familiarise yourself with the indoor and outdoor units before you install them in their working locations. This will allow you to calibrate the sensors and test the operation of the weather station.

Choosing a location

Things to consider before choosing where to install the outdoor unit:

• The rain sensor should be cleaned every 3 months and the batteries should be replaced every year. Make sure that the outdoor unit is mounted in an accessible location.
• Make sure that the operation of the outdoor unit is not hindered by nearby structures such as trees and buildings. A rule of thumb is to install it at a distance of at least four times the height of nearby obstacles. E.g. if a nearby building is 6 m in height, the outdoor unit should be installed 4 × 6 = 24 m away from the building.
• Avoid radiant heat from surrounding buildings, roofs, etc.
• Test the operation of the outdoor unit in the intended location before installing it. The range can also be affected by the type of obstacles located between the indoor unit and the outdoor unit (e.g. a concrete wall will interfere with the signal more than a plasterboard wall).
• Other wireless equipment using the same frequency band (433 MHz) can reduce the transmission range.

If you experience range problems, try the following:

• Turn off any other existing wireless equipment to check whether this is the cause of the problem.
• Reduce the distance between the units.
• Reduce the number of obstacles (walls, furniture, etc) between the units.

• The indoor unit has built-in temperature, humidity and atmospheric pressure sensors. The unit should therefore not be positioned where it might be affected by heat from heaters, cookers, fireplaces or other sources of heat.
• Avoid placing the unit next to metal objects such as metal window frames as this may cause interference with reception.
• The indoor unit can be used with the table stand (21) or hung on a wall using the hanging hole (17).

Outdoor unit

When you install the outdoor unit make sure that it is horizontal by using the built-in spirit level (27).

1. Orientate the marking on the weather vane. Make sure that the "S" mark is facing south.

Troubleshooting guide

The outdoor unit sensors send no data to the indoor unit.“--.-” is displayed.	When the indoor unit has lost contact with a sensor “--.-” or “--” will appear on the display.To scan for the sensors: Hold in [ CHANNEL/+ ] for 3 seconds. The symbol will show while scanning takes place.Check the distance between the indoor and outdoor unit. They should be 1.5–30 m apart.Try placing the outdoor unit higher up.Check that the outdoor unit LED indicator flashes every 16 seconds.Insert new batteries into the outdoor unit. Lithium batteries are recommended for use in cold climates.Check the batteries in the indoor unit are not discharged. Even if the indoor unit runs off the mains, discharged batteries may cause problems detecting the outdoor unit.Make sure that the wireless signal is not disrupted by nearby metal structures.Move the indoor unit away from other electronic devices such as routers, computers and TV sets.
The temperature/humidity readings of the indoor and outdoor units are different when they are placed beside each other.	Let the sensors stabilise for an hour. The temperature readings should not differ more than 1 °C (accuracy ±0.5 °C) and the humidity readings should not differ by more than 6 % (accuracy ±3 %).Adjust the values in the indoor unit, refer to the Calibration section.
Poor display contrast. Insert	new batteries into the unit.
The display shows rain even when it is not raining.	Make sure that the outdoor unit is securely mounted.If the unit is not rigidly mounted, e.g. is attached to a loose mast pole, it may send erroneous readings.
