Introduction

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 generator on/off.
An available channel on the sensor controller to read the C02 Monitor.

C02 Monitors

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 CO2 ppm.

Example: if the CO2 ppm was currently 1438, the monitor would be outputting 1.438 VDC on it's monitor port.

Connecting the C02 monitor

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. See my CO2 monitor setup here for software setup examples.

Connecting the C02 generator

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).
Done!
