4. Start-up

Open the battery compartment on the back of the thermometer/hygrometer, insert

the supplied batteries (2 x 1.5V AAA) and then close the battery compartment

again. Please be mindful of the correct polarity of the batteries (+/-). The

thermometer/hygrometer is now ready.

Setting the humidity alarm

1. In order to activate the humidity alarm, press and hold the SET button until

the ALERT and S symbols appear simultaneously in the upper part of the

display and the humidity indicator blinks. Now press the S or T button in

order to set (in 5% intervals) the upper humidity threshold.

2. Now press the SET button once more and ALERT and T will appear on the

lower part of the display and the humidity indicator will blink. Now press the

S or T 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 T or S 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 S or T 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 T /°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 S

or T button in order to set the upper mould threshold with a value of 60%,

65%, 70%, or 75%.

2. Press and hold the T /°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%

6. Warranty

WAAGEN-SCHMITT guarantees the free correction of defects resulting from

material or manufacturing faults through repair or exchange 3 years from the

purchase date. In the event of a warranty claim, please return the thermo-

/hygrometer with the receipt to your dealer, specifying the reason for the claim.

Please note: Under strong electromagnetic influences, e.g. when operating a radio

device in immediate proximity to the thermo-/hygrometer, interference with the

indicator values may be caused. After the disturbing influence has stopped, the

product may once again be used as intended, although a re-activation may be

necessary.

Legal duty to inform about battery disposal:

Batteries do not belong in household waste. As a consumer you are legally

obligated to return batteries. You can hand in your old batteries at the public

collection point in your community or anywhere where batteries of the same kind

are sold.

Please note:

These symbols can be found on batteries:

Li = Battery contains lithium

Al = Battery contains alkali

Mn = Battery contains manganese

CR (Li); AA (Al, Mn); AAA (Al, Mn)

Disposal of used electrical and electronic devices

This symbol on the product or its packaging indicates that

the product is not to be treated like normal household

waste, but must be handed over at a collection point for the

recycling of electrical and electronic devices. Further

information can be obtained in your community, at

communal disposal services or the business where you

bought the product.
