Operating Description
The two-colour led in the frontal panel (1) Fig. 1 may turn-on and be either red or green. On start-up,
when the receiver unit DRP A83 M01 is supplied the led (1) flashes in a sequence “green-red-green-
red” to show the correct working of the device. Afterwards the led becomes active according to its
normal functioning and the receiver starts to decode the signals issued by the transmitter as its
normal working.
In the normal functioning the red side of the led (1) displays the status of the output relay:
Red side turned-on means relay output ON
Red side turned-off means relay output OFF
The green side of the led (1) can turn-on at the same time of the red one’s, and in the normal
working it flashes rapidly giving an information about the quality of the signal received.
One flash: a command has been received and the signal is strong, the communication is reliable.
Two flashes: a command has been received, the signal is still sufficient but the communication might
be corrupted by occasional disturbances.
Three flashes: a command has been received from a transmitter in which is set an address different
from the one memorized in the receiver, and so the command has been ignored.
If more than one transmitter were installed in the close area, an indication of this kind has to be
considered normal. If the green side led flashes once and sometimes twice, the received
signal has to be considered good. In the normal working, the DRP A83 M01 receiving unit
continuously monitors the status of the communications with the thermostat to recognize a possible
malfunction of the system. Particularly if no command is received from the transmitter in 90
minutes, (i.e. if the battery of the transmitter is flat) the output will be put in an “alarm status”.
When in “alarm status” the output relay is turned-off and the red side of the led (1) displays this
status blinking. The “alarm status” ends as soon as a command is received correctly.
