Frequently Asked Questions - WS 1501 ADE

How to set the humidity alarm?

Press and hold the SET key until ALERT and ▲ appear. Use ▲ or ▼ to set the high threshold (30-95% in 5% steps). Press SET again to set the low threshold, then confirm by pressing SET or waiting 10 seconds.

How to enable/disable the humidity alarm?

Press the ON/OFF key once to activate (ALERT displayed) or deactivate (ALERT disappears) the alarm.

How to set the mold alert?

Press and hold the ▼/°C/°F key until MOLD ALERT ⊙ MOLD RISK appears. Use ▲ or ▼ to select the threshold (60%, 65%, 70% or 75%). Press and hold ▼/°C/°F again or wait 10 seconds to exit.

What does the HH.H or LL.L display mean?

HH.H indicates that the temperature or dew point exceeds 50 °C. LL.L indicates a value below 0 °C. This means the measurement is out of the operating range.

How to read the max/min values?

Press the MAX.MIN key to display the recorded maximum (MAX) or minimum (MIN) values. To reset, press and hold the key when the desired value is displayed.

How to change the temperature unit (°C or °F)?

Simply press the °C/°F key to switch between the two units.

What to do if the red LED flashes rapidly?

This indicates that the humidity alarm has triggered (humidity above or below the set thresholds). Press any key to stop the flashing. The alarm lasts one minute.

What to do if the red LED flashes slowly (every 5 seconds)?

This signals a mold risk: humidity exceeds the set alert threshold. Press a key to stop the LED. The symbols MOLD ALERT ⊙ MOLD RISK remain displayed as long as humidity is above the threshold.

How to interpret the color comfort index?

The display shows the perceived level: too humid (81-90%), humid (61-80%), comfortable (41-60%), dry (31-40%), too dry (20-30%). The thresholds are also visible in the 12-hour graph.

How to replace the batteries?

Open the battery compartment cover on the back of the device. Insert two AAA 1.5 V batteries respecting polarity (+/-). Close the cover. The device is then ready to operate.

Setting the humidity alarm

1. In order to activate the humidity alarm, press and hold the SET button until the ALERT and ▲ symbols appear simultaneously in the upper part of the display and the humidity indicator blinks. Now press the ▲ or ▼ button in order to set (in 5% intervals) the upper humidity threshold.

2. Now press the SET button once more and ALERT and ▼ will appear on the lower part of the display and the humidity indicator will blink. Now press the ▲ or ▼ button in order to set (in 5% intervals) the lower humidity threshold.

3. Press the SET button once more or wait approx. 10 seconds; the indicator then returns to normal mode again.
4. In order to activate the humidity alarm, press the ON.OFF button once. ALERT appears on the display
5. As soon as the humidity falls below or exceeds the values that you have set, the ▼ or ▲ symbol and, at the same time, the red LED alarm signal (quickly) blink.
6. In order to stop the blinking of the symbol and alarm signal, press any button.
7. In order to switch off the humidity alarm, press the ON.OFF button once. ALERT and ▲ or ▼ will no longer be displayed.

Remarks: The duration of the alarm is one minute.

Setting the mould alert

1. In order to activate the mould alert, press and hold the ▼ /°C/°F button until the MOLD ALERT ⊙ MOLD RISK symbols appear simultaneously in the upper part of the display and the humidity indicator blinks. Now press the ▲ or ▼ button in order to set the upper mould threshold with a value of 60%, 65%, 70%, or 75%.
2. Press and hold the ▼ /°C/°F button or wait approx. 10 seconds in order to return to the normal display mode.
3. As soon as the humidity exceeds the set mould alert value, there is a risk of mould formation. The symbols MOLD ALERT ⊙ MOLD RISK then appear on the display and, simultaneously, the red LED alarm signal blinks (slowly – every 5 seconds).
4. Press any button in order to stop the red LED alarm signal. The MOLD ALERT ⊙ MOLD RISK symbols remain visible on the display until the measured humidity falls back under the preset mould threshold value.

The factory preset value for the mould alert is 65%.

Selecting the temperature indicator (°C or °F)

In order to toggle between °C and °F units of temperature, press the °C/°F button.

Reading and resetting the record of maximum/minimum temperature and humidity.

In order to read the maximum or minimum temperature and relative humidity since the last time you reset the system, press the respective MAX.MIN button once. When the MAX symbol is displayed you can read off the maximum values, and when the MIN symbol is displayed you can read off the minimum values.

When the maximum values are displayed by MAX, the record can be reset and a new record started by pressing and holding the MAX.MIN button.

When the minimum values are displayed by MIN, the record can be reset and a new record started by pressing and holding the MAX.MIN button.

5. Important Information

How does the humidity affect your health and your home?

Excessive humidity indoors promotes the growth of undesirable organisms. The maintenance of humidity in the range between 30% and 50% indoors contributes to preventing the growth of mould, mildew, and mites. Staying in rooms infested with mould can damage the human immune system, weakens the resistance to respiratory allergies, and has been linked with infections.

Excessively dry air indoors can dry out the skin, irritates the throat and paranasal sinuses, and contributes to the easier infection of these areas. In a dry climate or in winter, when the air indoors has been made dry by heating, the relative humidity can be increased with the help of a humidifier.

Indoor air that is excessively dry can cause wood to contract and split, particularly thin wood such as that used in the making of guitars and violins. During extreme dryness over a long period of time, the splitting of solid wooden beams or plaster is also possible.

Active heating and ventilating can contribute to creating a comfortable and healthy living climate.

Information on the dew point

The dew point is a measure for determining the moisture in the air and is calculated from the relationship of relative humidity to temperature. It defines the temperature at which moisture in the air condenses.

The warmer the air, the more moisture it can transport. If dew point and temperature are exactly the same, the humidity is 100% i.e. the air is saturated

and the moisture condenses – e.g. indoors on walls, outdoors it leads to the formation of fog or precipitation.

Normal indoor air at 22^ C and 40% humidity, which is generally found to be comfortable, has – for example – a dew point of approx. 8^ C. This information is particularly helpful for preventing the formation of mould. As soon as the temperature of e.g. external walls reaches the dew point or falls below it, moisture will be deposited; in the long term this can lead to the formation of mould.

Remarks: The dew point temperature range of the hygrometer extends from 0^ C to 50^ C. If the dew point temperature exceeds 50^ C, “HH.H” appears on the display; if it is below 0^ C, “LL.L” appears on the display.

Graphical representation of humidity within the last 12 hours.

In the graphical representation, you can easily read the record of the relative humidity and the perceived level in the room within the last 12 hours.

Perceived level (comfort index)	Relative	humidity
Too wet 81% to 90%
Wet 61% to 80%
Comfortable 41% to 60%
Dry 31% to 40%
Too dry 20% to 30%
