Configuring The System - Elesta RTM508B Mode D'emploi

- Before making any connections make sure the mains
power is disconnected.

CONFIGURING THE SYSTEM

The receiving system is made up of at least one "active
antenna" and one "relay module". Several relay modules can
be connected in cascade to increase the number of available
outputs.
Carefully make the power connections and output
connections on the device and then, with the power supply
still disconnected, plug the cable for connecting the active
antenna to the relay module into the corresponding sockets.
The cable leading from the active antenna must be plugged
into the socket marked "SIGNAL IN".
If you intend to use additional relay modules in a cascade
connection, you must connect the "SIGNAL OUT" socket
of each module to the "SIGNAL IN" socket of the module
following it in the chain, using the cable provided.
The last device in the chain will have the "SIGNAL OUT"
socket free. Using the "SIGNAL IN" and "SIGNAL OUT"
sockets up to 10 relay modules can be connected together.
Carefully inspect each connection and then continue with the
self-learning procedure.
Self-learning procedure
- Switch on the relay module: the LEDs will blink for a few
seconds during the initialisation phase.
- Switch on a single thermostat or chronostat and set it
in the "test" mode (this means that the transmitter will
continuously emit an ON command followed by an OFF
command after three seconds).
- It is advisable to keep the transmitter in the same room
as the receiver, positioned at a distance of no less than 1
metre from the active antenna.
- In order to link each individual transmitter to the desired
receiving channel it is necessary for the module to learn
the transmitter "address" code, which will be stored in a
non-volatile memory. To carry out this procedure simply
press the button corresponding to the channel you want to
"associate" with the transmitter for one second during the
"test" phase.
This will launch the "self-learning" procedure and the LED
of the channel in question will rapidly blink yellow. If you
wish to memorise the address of the same transmitter on
several channels you can press the button of the other
channels and the corresponding LEDs will blink yellow.
- As soon as a test command is received, the LED associated
with the channel will remain steadily lit yellow for 7
seconds. During this time the module will continue to receive
test commands and memorise only the signal received at
the highest strength. This means that it will memorise
the signal coming from the nearest transmitter and will
thus avoid learning addresses from any transmitters in the
test mode which are not meant to be connected to the
system.
- After 7 seconds have elapsed the procedure will be
terminated and the corresponding LED will blink red-green-
red-green in sequence to indicate that the transmitter
address has been saved.
- The module will resume normal operation and the output
relay of the channel for which the address has been
memorised will immediately start to switch ON and OFF
following the commands emitted by the transmitter in the
"test" mode.
Using the "test" function it is advisable to check the
strength of the signal received once the transmitter
has been placed in the desired position. To avoid wrong
indications due to overlapping signals, do not test more
than one transmitter at a time.
- After verifying that the signal strength is satisfactory,
you may proceed with the final mechanical and electrical
installation.
NOTES
The device can indicate which channels an address code
has or has not been associated with. See paragraph on
"Procedure for associating thermostats with a chronostat".
If the system uses fewer than eight thermostats and
therefore does not use all of the outputs, it is important to
keep the unused channels "inactive" by not assigning them
an address code.
The device will ignore the inactive channels, since they
are not connected to any valve: this configuration is very
important to ensure the correct control of the auxiliary
output for the circulation pump.
Configuring a channel as "inactive"
The relay module has all channels in an "inactive" status
when it leaves the factory; however, if an active channel
needs to be configured as "inactive", the address assigned to
it can be "erased" by means of the following procedure:
- Press the button corresponding to the desired channel
(Figure 2) and keep it pressed down.
- The corresponding LED will rapidly blink yellow and after a
few seconds it will blink red-green-red-green in sequence.
- Release the button: the channel is now inactive.
When a channel is "inactive" it will be ignored for all functions
and its respective relay will always remain off, irrespective of
the signals received. Making a channel inactive will also have
the effect of cancelling any association with a chronostat.
Resetting to factory status
If you want to erase all of the memorised addresses,
associations with chronostats, NO/NC configurations and
periodic activation of outputs, thus restoring the module
to its original factory status, you can carry out a reset
procedure as follows:
- Disconnect the power supply.
- Press the association button "A" (Figure 2) and keep it
pressed down.
- Switch the power back on.
- Continue pressing the association button "A" (about 3 sec)
until the output LEDs start blinking like they normally do
when the device is switched on.
- Release button "A"; the module will restart and the
memory of each channel is erased.
Auxiliary output for pump or boiler
The relay of the auxiliary output is activated each time at
least one actuator output is switched on.
If the "share auxiliary output" option is enabled (see
paragraph on "DIP-switch options") the relay will be
controlled according to the status of the channels of all
modules connected in cascade to one another.
If the option is disabled, the relay will be activated based
solely on the status of the outputs of the module the relay
