10. OPTIONS
10.1. CO2 SENSOR
Output: analogue 1 x 0-10V or 4-20mA (switchable) + 1 x changeover
contact (adjustable).
Measuring range: 0...2000ppm or 0...5000ppm (switchable).
Display: without.
Protection class: IP30.
Brand: S+S Regeltechnik.
The connection of this sensor can be found on page 13 of the wiring diagram (See APPENDIX). Terminal
block X3 is located in the intermediate compartment.
The cable (here named CO2) will be supplied by the customer. The 4/20mA signal requires a twisted +
shielded cable with at least 3 conductors of 0.5mm2.
This cable enters the machine through a grommet on the top of the machine. It will be enough to pierce the
plastic to slide the wire in, to put the cable gland without locknuts.
Then the cable CO2 runs along other cables to terminal block X3.
X3-1 = 24Vac
X3-2 = 0V
X3-19 = Sensor signal.
The rst calibration of the probe will be done at the factory. The auto calibration(DIP SWITCH) will be
disabled:
DIP SWITCH = ON-ON-OFF-OFF-OFF
The controller opens the fresh air supply depending on the CO2 level in the room area of the sensor. It
displays a message in the alarms if there is no 4/20mA signal (a problem with the probe connection) or if
the value read is >2000ppm.
NOTE: for more information refers to the Installation manual of CO2 sensor.
RCO2-W
RCO2-W room sensor with active/switching output, automatic calibration
(can be switched off), for determining the CO2 content in the air (0...2000
ppm / 0...5000 ppm). The transmitter converts the measured values into a
standard signal of 0 -10 V or 4...20 mA (switchable).
