INSTALLATION
The receiving system consists of at least one active antenna and a relay module.
The best place to install the device should be decided based on the following
points:
- The antenna was designed within a small enclosure so that it could be easily
installed where the radio signal is the strongest.
It is often the case that the place where the relay module is installed is not a
good position for the antenna.
- The worst case scenario is when the relay module is installed in a metal
frame. The antenna must definitely be positioned completely outside the
metal frame.
- As the radio signals are strongly reduced by metal shielding, the antenna
should be positioned as far away as possible from metal grilles or objects.
- Attention must also be paid to the type of wall on which the antenna is fixed.
It must not be metallic or have an inner metal structure.
- The radio signals within a building are reflected by walls, floors, furniture
and other objects. Therefore it may be the case that some areas of a building
have no reception, while other zones have a very good reception. Even moving
the antenna only by half a meter can cause a considerable improvement in
the reception. Once the position where the antenna will be installed has
been chosen, you need to check the system to make sure that the signals
are received from all the transmitters. Consult the documentation of the
thermostats to carry out this operation. Once the system has been checked
successfully, carry out the final installation of the device.
In order to finally install the device follow these directions:
- Remove the cover using the screwdriver as a lever on the plastic tabs, shown
2
with in Fig. 1-2, pressing down lightly between the tab and the hole in
the plastic, without pushing down directly on it to avoid it breaking. Fig. 2
shows the cross-section of the plastic enclosure to emphasize how to use the
screwdriver correctly.
- Once the best place for installation has been identified, fix the bottom of the
device onto the wall using two screws and the two holes spaced 60 mm apart.
