INSTALLATION
Attention: after the installation, it may take several hours up to a day before the correct values are displayed. Additionally, after replacing exhausted batteries in the indoor unit, all measured data in the indoor unit will be erased.
Power supply:
Advice regarding batteries:
We advise you to use normal alkaline batteries of high quality for the indoor
unit. Alkaline batteries with a capacity of 2000mAh have a lifespan of over
one year. Rechargeable batteries are not recommended because of their lower
supply voltage.
Also, the outdoor unit is powered by 3 AA 1.5Volt batteries, but because
normal Alkaline batteries perform poorly or not at all at temperatures of
around or below 0°C, it’s not recommended to use standard Alkaline batteries
for the outdoor unit.
For that reason, we advise you to use Lithium batteries for the outdoor unit
that are designed to function well within a temperature range of -20°C to
60°C. These batteries can be ordered via the service department of Alecto at
www.alecto.info Lithium batteries with a capacity of
2900mAh have a lifespan of over one year.
Indoor unit:
Slide down the battery cover at the rear of the unit and insert 3 AA 1.5V
batteries according to the markings inside the battery compartment. Slide the
battery cover back onto the indoor unit. (Batteries are not included) The
indoor unit will now start a 1 minute scan to search for the outdoor unit.
Therefore, you’ll need to insert the batteries into the outdoor unit within
that minute.
Outdoor unit:
Open the battery compartment by loosening the battery cover using a small
crosshead screwdriver. Install 3 AA 1.5V batteries according to the picture
below, paying attention to the correct polarity (+ and -). Replace the cover
and fasten the screw (batteries are not included).
Pairing the indoor unit/outdoor unit:
Automatically:
As soon as you insert the batteries into the indoor unit, the indoor unit will
start a 1-minute scan to search for the signal of the outdoor unit. Therefore,
if you insert the batteries into the outdoor unit within that minute and the
units will ‘find’ each other, they will be automatically paired and the
display of the indoor unit will show the temperature transmitted by the
outdoor unit.
Manually:
If the units cannot be paired automatically, or after replacing the batteries,
you can pair the outdoor unit (again) with the indoor unit as follows:
- press and hold the SCAN button on the indoor unit for 2 seconds until the antenna symbol starts flashing in the display
- Press briefly press the RESET button on the outdoor unit
- the units will have found each other (again) after several seconds
Positioning: reset
Indoor unit:
You may suspend the indoor unit from a simple screw in a wall or use it as a
desk model with the supplied support. In any case, never place the indoor unit
in direct sunlight or next to heat radiating lights or stoves.
Outdoor unit:
You may place the outdoor unit on a flat surface (such as a fence or railing)
or on top of a pole (not included). In any case, make sure the unit is placed
at least 1.5 meters above the ground and ensure the unit is standing freely in
the rain and wind.
Outdoor unit positioning tips:
To ensure that the rain meter is functioning as accurately as possible, the
outdoor unit must be standing exactly horizontal. You can verify this by using
the built-in spirit level at the top of the outdoor unit.
To be able to check from which direction to the wind is coming, the outdoor
unit should be aimed to the North. To do this, use the N marking on top of the
outdoor unit. Use an accurate compass (not included) to properly orient the
unit.
Make sure that the distance between the outdoor unit and indoor unit is no
greater than 50 to 100 meters.
Clock:
Introduction
The WS-4700 is provided with a built-in DCF receiver that receives the DCF
time signal from Frankfurt. This signal ensures that the clock shows the time
very accurately, provided a strong enough signal is being received.
Automatically:
As soon as you insert the batteries into the indoor unit, the clock will start
searching for the DCF radio signal for the time while the antenna symbol is
flashing. After several seconds or minutes the WS-4700 will start showing the
correct time. In extreme cases, it can take over a day before the DCF time is
shown.
Manually:
If the clock cannot receive the radio signal or cannot receive it well enough,
you can set the clock manually as follows:
- press and hold the button for 2 seconds, 12Hr or 24Hr will appear in the display
- Use / to set the time format, then briefly press the button
- use / to set the hours and then briefly press the button
- use / to set the minutes and then briefly press the button
- use / to set the seconds to 0 (this allows you to have the clock run synchronously with your own clock) and then briefly press the button
- use / to set the year and then briefly press the button
- use / to set the month and then briefly press the button
- use / to set the date and then briefly press the button
- use / to set the hour difference compared to the DCF time. E.g. for use in the Benelux select ‘0’ and then briefly press the button.
- use / to set the language in which the day must be displayed, you may choose from: EN (English), FR (French), DE (German), ES (Spanish), or IT (Italian), now briefly press the button.
- use / to determine whether the clock must switch to daylight saving time or standard time automatically (AUTO) or whether you prefer to do this manually (OFF), now briefly press the button.
The clock is now set manually.
When the DCF receiver is enabled and a strong signal is being received, the
receiver will overwrite the clock display.
Switching the DCF receiver on/off:
You can turn off the DCF receiver as follows, allowing you to have only the
time and date shown on the display according to your programming:
-
turn off: press and hold the RCC OFF button at the rear of the indoor unit for 8 seconds until the antenna symbol disappears.
You can turn the receiver back on as follows: -
turn on: press and hold the RCC ON button at the rear of the indoor unit for 8 seconds until the antenna symbol starts flashing.
The symbol in the upper middle part of the display shows the status of the DCF
clock:
no symbol: the DCF receiver is disabled; the displayed time is provided by the
internal clock of the WS-4700
flashing: the DCF receiver is enabled and is searching for the DCF signal; the
displayed time is provided by the internal clock of the WS-4700
remains lit: the DCF receiver is enabled and is receiving the DCF signal; the
displayed time and date are provided by the DCF atomic clock in Frankfurt
To reset measurement data:
After the installation is completed, press and hold the HISTORY button for 10
seconds to delete all of the measurements made up until that moment. This
ensures that you won’t see any measurements at a later time that were caused
by movements during the installation.
