Connection to the main controller
Recommended supply voltage of the wireless
room panel is the 12 VDC.
Wireless room panel can be
supplied with 5÷12 VDC. However,
it is not recommended due to
voltage losses in long connection
wires.
The 4-wire cable with a max. length of 30 m
and cross-section of min. 0.5 mm
2
is
required to connect to the main controller
terminals.
When the wireless room panel is
wired with the main controller, the
radio transmission is switched off.
Terminal signal outputs in the rear side of
the wireless room panel:
Be careful to connect the poles
correctly. Incorrect connection may
cause damage to devices.
In wireless cooperation a room panel with a
main controller, connect the radio module to
the main controller, according to point. 11.
The wireless room panel requires
an
external
power
supply
connection.
To do this, use the 12 VDC mains adapter,
min. 0.5 A, which must be connected to the
room panel connector with correct polarity.
The room panel can be powered directly from
the main controller socket, using a 2-wire
cable, which should be connected in
accordance with point. 12, omitting the
connection of the D + and D- signals.
To connect the room panel power
supply, you can use a 2-wire cable
available in houses, provided for
thermostats and run between the
boiler room and the living room, to
which we connect the power supply
unit and the wireless room panel.

Radio module
11.1
Installation and connection of the
radio
module
to
the
main
controller
The radio module should be mounted on a
wall near the installation location of the main
controller. If the radio connection is poor, try
placing the module in other places. Moving
the module even by a few centimeters can
affect the quality of the connection.
Placing a radio module in a metal
casing, e.g. a mounting box, a
metal boiler casing, etc., will
dampen the radio signal and thus
interfere with the operation of this
module.
The radio module should be screwed to the
wall with mounting screws. Access to holes
for assembly screws is obtained after
unscrewing the cover of this module.
Terminals D +, D-, GND, 12 VDC of the radio
module should be connected to the RS485
transmission socket of the main controller.
