OPERATION
The active antenna, together with one or more relay modules, is the receiving
part of a wireless system intended to be used for temperature regulation.
The device connects with the relay module through a 6-pin data cable and
communicates with the RS485 bus. Every relay module can extend the
communication bus module by means of additional modules and relevant data
cables.
Up to a maximum of 10 relay modules can be connected to the same active
antenna.
The device can be configured to work as a repeater, that is re-transmitting
the radio commands received from one or more wireless devices that have
difficulties in reaching the receiver. In this way, it is possible to solve problems
of transmission distance in difficult environments or to double the distance that
can usually be reached.
Alternatively, the device can be connected to a PC or a home automation
controller instead of a relay module, with which it will communicate through the
RS485 bus. In this way, it is possible to receive all the commands coming from
the radio thermostats to the home automation controller, which will manage
the control outputs of the heat regulation system and a user interface, if any.
The relay modules provide the power supply in direct current through the data
cable. If the device is used as a repeater or receiver connected to a PC, it must
receive the power supply through the two terminals duly shown with 1- and
2+ (Fig. 4).
Working as a repeater
The device is factory configured to operate as an active antenna.
To configure the device as a repeater, remove the JP1 jumper and leave JP2
inserted (as shown with B in Fig. 5). The device works as a repeater and no
longer communicates with the relay modules. In this configuration, 12VDC
power supply must be supplied to terminals 1- and 2+.
Carry out the self-learning procedure of the device's address, on which you
want to repeat the radio command:
- Turn on the thermostat or other transmitting device and set it up in "test"
mode. (This means that it will continuously transmit an ON command,
