7. INSTALLATION

EN
7.1 Installation of the control device
This device is installed in a housing to be snapped onto DIN rails (DIN EN 50022-35). It is designed to be mounted in
DE
switchboxes and distribution panels.

7.2 Installation of the ground temperature and moisture sensor VIA-DU-S20
RU
The sensor is yellow and can be recognised by its 5-core connection lead.
It has the following dimensions: see
The ground temperature and moisture sensor is to be installed within the heated area at least 2.5 cm and maximum
15 cm away from the heating cables (see diagram).
The sensor must be able to directly detect weather conditions (rain, snow, melted
snow and ice). The sensor may not be covered up (e.g. when clearing snow).
Take care that VIA-DU-S20 is not installed in an area which is continuously flooded with water (e.g. drain line), neither
in an area which is continuously under ice due to external parameters (e.g. freezing of condensation water in
cooling rooms).
The piece of wood is placed into the ground surface as a dummy for the sensor.
A metal protective pipe is to be installed up to the wooden piece. The pipe is to be secured on the wooden piece to
prevent concrete, asphalt, etc. from getting in. Once the material has been put on and if necessary cooled, the piece
of wood is removed and the sensor fitted into the hole. The sensor must be mounted absolutely horizontal. The
remaining space around the sensor is to be filled with, for example, silicon, mortar or asphalt. The temperature of
the filling material must not exceed 80°C. Furthermore, it has to be ensured that there is a good connection without
hollow space between the sensor and the filling material. The sensor connection lead may be extended from 15 m
(standard length) to a maximum of 50 m with a diameter of 1.5 mm² .
7.3 Installation of air temperature sensor VIA-DU-A10
The sensor has the following dimensions: see
The air temperature sensor should be installed approx. 2-3 m above the ground in a protected place (with a shelter). It
must not be exposed to direct sunlight. It must also be protected from external influences, i.e. it must not be installed
above doors or windows or near lamps or headlights.
The sensor connection lead may be up to 100 m long, given a diameter of 1.5 mm².
