thermohygrometer BZ15M

Correct airing:

If your window panes mist up frequently or mould starts to grow

on walls, it is high time to review and, if necessary, break your

old habits. The answers to the following questions can be

useful:

• How often should I air out?

This question can be answered by taking a look at the

hygrometer scale. Whenever the hygrometer and

temperature pointers are outside the designated colour

range, it is a good idea to air out the room.

• For how long should I air out?

This is also indicated on the hygrometer: During the winter,

at temperatures below approx.+5°C, a maximum of

5minutes should be sufficient. If the outdoor air is warmer

(5 to 15°C), about 10 to 15minutes of airing are required.

• How should I air out?

An effective air exchange can only be obtained by leaving a

window or window door in the room wide open. It is not

necessary to create a draught. Airing a room by tilting a

window or door over an extended period of time is

generally insufficient and a waste of energy, especially

considering that the affected room will cool down much

more over time if the temperatures are low.

• What should I do if I am not at home during the day?

Airing your rooms sufficiently while you are at home will

do. Ideally, this means airing out once every morning

before you leave, once when you come home, and once

before you go to bed. It is equally important not to switch

off the heating completely during the day (16 to 18°C).

• Should I also ventilate in case of fog or rain?

This is certainly recommendable. Even very moist, cold air

always has a lower moisture content than normal indoor

air. Besides, you also need a sufficient supply of fresh air

when the weather is damp.

• What do I have to note in the summer?

Except for the basement, you can air out all rooms as

needed. There is no limitation on the hygrometer scale; the

humidity level always corresponds to the outdoor climate.

This is not harmful since the walls (except basement walls)

are usually warm enough to prevent the temperature from

falling below the dew point in normal living areas, and thus

to avoid the formation of condensation e.g. on wall

surfaces, which would promote mould growth.

• How should I air out basement rooms?

Basement rooms are at risk in the summer because during

this season the warm outdoor air contains much moisture,

which precipitates on cold surfaces.

• Can I dry laundry in the flat?

The ideal solution is a drying room that can be aired out

permanently (even in the summer or in case of frost). Apart

from that, laundry may only be dried in the flat if the room

is closed and very well heated. The room should be aired

out intensively several times during drying.

Information regarding the hygrometer

The measurement accuracy is +/-3%RH in the range from

20 to 100%RH. The hygrometer's measuring element is a

specially pre-treated synthetic fibre which, unlike real hair,

guarantees a high measurement accuracy without requiring

maintenance.

Please note that the hygrometer must not be exposed to hot

water or water vapour, otherwise the measurement accuracy

can no longer be guaranteed. If deviations occur in comparative

measurements carried out with a reference device, the

hygrometer indication can be corrected, see chapter

Maintenance and repair.
