HUMIDITY SENSORS
• If humidity sensors are used, connect
them to the terminal block of the con-
nection box by connecting the first hu-
midity sensor to %RH1, in place of the
6K8 resistor in the terminal block (re-
move the resistor in this case), and the
second humidity sensor to %RH2. See
the electrical diagram.
CARBON DIOXIDE SENSORS
• Carbon dioxide sensors are connected
individually.
• When the first carbon dioxide sensor 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 carbon dioxide sensors.
The sensor is wired straight from the electrical connection box of the unit.
The CO
2
sensor is connected directly from the connection box of the unit, or in series with
another CO
2
sensor or control panel (see External electrical connections on page 7).
