Controlling a C02 generator with JAuto requires four things:
- A C02 generator (obviously)
- A C02 Monitor
- An available channel on the relay controller to turn the C02
- An available channel on the sensor controller to read the C02
I've been using a GreenAir CDM-1 (which is a private label
Telaire model 1050). Of the current Telaire models, the 8102 is
the model I'd probably buy. Other vendor's products should work
as long as the monitor outputs a DC voltage that represents the
Example: if the CO2 ppm was currently 1438, the monitor would be
outputting 1.438 VDC on it's monitor port.
- The Telaire monitor port looks like a headphone
jack. The tip of the plug is positive, and the
jacket is negative.
- Connect the positive lead on the monitor port to the
positive side of a channel on the B3001.
- Connect the negative lead on the monitor port to the
negative side of the same channel on the B3001.
- Setup the C02 monitor in the 'Sensors' tab of JAuto.

here for software setup
Note: These instructions assume the use of a
generator that will turn ON when 12 VDC is applied, and turn off
when that voltage is dropped. I use a GreenAir CD-6
generator and it follows this behavior.
- Connect the positive lead on the generator to the
positive side of a channel on the B2102.
- Connect the negative lead on the generator to the
negative side of the same channel on the B2102.
- Setup the relay channel in the software. See my CO2 setup
screens here for software setup
examples (note the On/Off Conditions tabs).
