- Damage to objects

• Mounting, electrical connection and wiring of the device/product must be carried out only by a qualified technician
who is familiar with and observes the engineering regulations, provisions and standards applicable in each case.

• Repairs and maintenance may only be carried out by trained staff or Adolf Thies GmbH & Co. KG. Only
components and spare parts supplied and/or recommended by Adolf Thies GmbH & Co. KG should be used for

repairs.

• Electrical devices/products must be mounted and wired only in voltage-free state.

• Adolf Thies GmbH & Co KG guarantees proper functioning of the device/products provided that no

modifications have been made to the mechanics, electronics or software, and that the following points are
observed:

• All information, warnings and instructions for use included in these operating instructions must be taken into
account and observed as this is essential to ensure trouble-free operation and a safe condition of the measuring
system / device / product.

• The device / product is designed for a specific application as described in these operating instructions.

• The device / product should be operated with the accessories and consumables supplied and/or recommended

by Adolf Thies GmbH & Co KG .

• Recommendation: As it is possible that each measuring system / device / product under certain conditions, and
in rare cases, may also output erroneous measuring values, it is recommended using redundant systems with

plausibility checks with security-relevant applications.

Environment

• As a longstanding manufacturer of sensors Adolf Thies GmbH & Co KG is committed to the
objectives of environmental protection and is therefore willing to take back all supplied products

governed by the provisions of "ElektroG"

and to perform environmentally compatible disposal and recycling. We are prepared to take
back all Thies products concerned free of charge if returned to Thies by our customers
carriage-paid.

• Make sure you retain packaging for storage or transport of products. Should packaging
however no longer be required, arrange for recycling as the packaging materials are designed
to be recycled.

2 Application

The Hygro-Thermo Transmitters of our compact series are designed to measure relative humidity,
the temperature of the air and other non-aggressive gases.

The use of capacitive humidity sensors is a guarantee for:

• a high degree of long-term stability

• nearly linear characteristics

• good dynamic behaviour

• dewing stability

• low temperature coefficients

• low hysteresis

The hygro-thermo transmitter is equipped with a protective filter for the sensors.

Type: Membrane-filter with gauze ZE20 (order-no. 1.1005.54.901) for protection against
dust in case of field application.

Remark:

For filed work, it is advisable to use a „Weather and Thermal Radiation Shield“. It
is optionally available as accessory.

3 Mounting

For correct measurements, the Hygro-Thermo Transmitter should be mounted at a site in the room
which is representative of the climate within the room. The mounting position itself is arbitrary.
Mount the sensor such that water cannot penetrate the inside of the sensor. Dewing and sprinkling
water do not damage the sensor.

Moreover, please make sure to keep the operating voltages as well as a good recirculation
ventilation of the instrument. Deviations might lead to measurement errors (for example: due to
instrument warming).

Preferably, the sensor should be mounted vertically facing downwards to a wall (indoor application),
and should be mounted horizontally facing backwards in canals.

5 Maintenance

The Hygro-Thermo Transmitter is supplied already adjusted and its characteristics remain stable for
years.
Dust does not damage the humidity sensor but does influence the dynamic behaviour negatively. If
the instrument is very dirty, the sensor element can be cleaned or carefully rinsed in distilled water.
Make sure you do not touch the highly-sensitive sensor element.
Before cleaning the sensor elements please remove the protecting filter; it should be cleaned, as
well or should be replaced.

Attention:

The instrument housing with the electronics included should
be opened only in the factory.
