Control panel mounting, detaching and wiring
The control panel is wired (2 m cable lenght) directly from the KWL EC 300 Pro connection
box. The control panel can also be wired serially with a CO
2
sensor or another control panel.

CO
2
sensors are connected
individually.
When the first
CO
2
sensors
has been connected to the
system, the unit is
switched on. After this, the
unit gives the sensor an
address. Follow the same
steps for other
CO
2
sensors.
Humidity sensors
When mounting two or more humidity sensors,
connect them to the terminal block of the
connection box by connecting the first humidity
sensor to %RF1, in place of the resistor 6K8 in
the terminal block (remove the resistor in this
case), and the second
humidity sensor to %RF2.
See the electrical diagram.

MOUNTING OF CONTROL PANELS AND SENSORS
Several control panel addresses
If two or more control panels are connected to the system, the addresses of the control
panels have to be changed. (See Page 14, Section 1.3.12)
For example 3 control panels.
Connect the first control panel to the unit and change its address to 3.
Connect the second control panel to the unit and change its address to 2.
Connect the third control panel and check to see if its address is 1.
If control panels have the same address, they go to bus fault state. In this case, remove one of the control panels
and change the address of the other panel. The above mentioned situation can arise in connection with the later
installation of an additional control panel.
The cables to sensors are laid
directly from the connection box
of KWL EC 300 Pro.
The CO
2
sensor can be con-
nected to KWL EC 300 Pro
directly from the connection
box or in series with another
CO
2
sensor or control panel
(see external electrical con-
nections, on page 17).
