Electric Connections - Bpt TH400TX-RX Gebrauchsanweisung

1 - LOCATION
The TH400RX receiver (single-
channel) can be installed near the
equipment to be controlled (e.g.
solenoid valve, motor-driven valve,
fan-coil). In the event the receiver is

installed in rooms with reception
problems, a normal radio-amateur
aerial must be connected in place of
the aerial supplied on the 430 MHz
range, and the aerial installed in an
area where reception is good. Use a
coaxial cable for the connection.
2 - INSTALLATION
The unit features a relay for con-
trolling heating and air conditio-
ning. It can be installed, without
terminal covers, in a box equipped
with a DIN guide (EN 50022), or
can be wall mounted using the DIN
guide supplied and applying the
terminal covers.
NOTE. The wire (18 cm-long uni-
polar cable) used as an aerial must
be straightened out and connected
to the terminal (see fig. 1).
