4. Connection Diagram

Note:
In Greenhouse Mode the piggyback plug controls CO2 regulator or generator. In
Ventilation Mode the piggyback plug controls an exhaust fan.

4.1. How it Works

1.
The Power (Red LED) is on when the power is supplied.
2.
Greenhouse Mode: The DayLight (yellow) LED will light when the photo
sensor is active. The photo sensor detects the presence or absence of light.
When light is present, and CO2 levels are between the Target Lo and
Target Hi CO2 levels, the Active (green) LED is on and power will be
supplied to the piggyback plug. When CO2 levels reach the Target Hi level,
the Active (green) LED will turn off, the CO2 High (red) LED will turn on,
and power will be cut to the piggyback plug. In darkness, the piggyback
plug is not powered regardless of the CO2 level.
3.
Ventilation Mode: If CO2 levels are higher than the Target Hi level, the
Active (green) LED will turn on and power will be supplied to the piggyback
plug. When CO2 levels decrease below the Target Lo, the Active (green)
LED will go off and power will be cut to the piggyback plug. In ventilation
mode, the photo sensor is always disabled.
