Mechanical Construction
In Fig. 1 is visible the external appearance of the DAE A83. To install the receiving unit it is
necessary to access to the internal parts. To open the plastic case, remove the frontal panel using a
small screwdriver to drive the plastic teeth (1) shown in Fig. 2. Apply a light pressure with the
screwdriver between the tooth and the hole in the plastics, but do not push directly on the tooth in
order not to break it.
The Fig. 2 represents also the plastic box section and shows how to
handle the screwdriver correctly.
In Fig. 3 is shown the receiver’s internal layout, and the location of
the ‘SIGNAL OUT’ plug (2).
Installation
Instructions Electrical installation is very easy, simply connect in the ‘SIGNAL OUT’ plug the proper data cable. The data cable must then be connected to a relay module such as DLP 600 M or DLP 200 M. See
the relay module’s instruction sheet for more information. The best position where to install the DAE
A83 antenna should be decided taking into account the following:
1) The antenna has been designed to fit in a small case to be easily installable in the best location
for the radio signals to be received. Often the relay module’s place is not a good place for the
antenna too. The worst case is when the relay module is mounted inside a metal frame: the antenna
must be definitely be placed outside the metal frame.
2) Since the radio signal are strongly attenuated by metal screens, the antenna should be placed as
far as possible from metal grids and objects.
3) Care must be taken also at the wall, which the antenna will be fixed on. It must not be a metallic
wall or have a metallic frame inside.
4) Radio signals inside a building are reflected by walls, floors, furniture and other objects, it might
happen that some room’s areas are bad for the signal reception, and some others might be good.
Moving the antenna half a meter often determines a considerable different receiving performance.
Once the antenna’s position is chosen, the system should be tested, to ensure that all the thermostat
transmitters’ signals are correctly received. See the thermostat’s documentation how to do that.
After the system has been successfully tested proceed with the definitive installation of the DAE A83
by fixing it on the wall with two screws, using the holes with distance between axes of 60 mm visible
in Fig. 3 (3). While working with tools in the screw holes, be careful not to damage the internal
circuits or any other component. Once the installation has been completed, close the plastic case by
carefully positioning the front panel, then slightly press the panel in order to make the four plastic
teeth snapping.
WARNING !
- To determine the correct position ensure that the radio signals transmitted are correctly
received by the receiving unit.
- Installation and electrical wirings of this appliance must be made by qualified technicians
and in compliance with the current standards.
- Before wiring the appliance be sure to turn the mains power off.
