CONTROLLER MODES
Pressing the mode button will cycle through the controller’s available programming modes: OFF,
ON, CO
2
(Center and Zone), Fan (Center and Zone), and CYCLE (On and Off). Make sure to use
the appropriate mode for the device you’ve plugged in (ex. CO
2
mode for CO
2
generator).
ON MODE
Your device(s) will switch on regardless of CO
2
levels or time-based triggers.
OFF MODE
Your device(s) will switch off regardless of CO
2
levels or time-based triggers.
Jump back to OFF Mode anytime by holding the
MODE button while in other modes or settings.
PROGRAMMING
16
STEP 1
Ensure you are in the correct numbered outlet for the CO
2
generator you are using. Then navigate to the Center submode.
STEP 2
Use the up or down buttons to set the center
value and your desired CO
2
level. Press the mode button to
navigate to the Zone submode.
STEP 3
Use the up or down buttons to set the zone value and establish
an activation buffer around the center value.
Your CO
2
generator will switch on if the reading falls below this
threshold. When the reading rises above this trigger point, your
CO
2
generator will switch off.
In this example, the center value is 1200ppm and the zone
value is 400ppm.
Your CO
2
generator will switch on when the current CO
2
level is
below 1000ppm [1200 – (400/2)].
The CO
2
generator will turn off when the current CO
2
level is
above 1400ppm [1200 + (400/2)].
The set zone value is the
buffer around your set center
value that is equal to half its
setting. (ex. 400ppm. Buffer
zone is 1000-1400ppm).

STEP 1
Ensure you are in the correct numbered outlet for the fan you
are using. Then navigate to the Center submode.
STEP 2
Use the up or down buttons to set the center value and
high CO
2
trigger. Press the mode button to navigate to the
Zone submode.
STEP 3
Use the up or down buttons to set the zone value and establish
an activation buffer around the center value.
Your fan will switch on if reading meets or exceeds this
threshold. When the reading falls below this trigger point, your
fan will switch off.
In this example, the center value is 1500ppm and the Set Zone
is 1000ppm.
Your fan will switch on when the current CO
2
level meets and
exceeds 2000ppm [1500 + (1000/2)].
The fan will turn off when the current CO
2
level is below
1000ppm [1500 - (1000/2)].
The set zone value is the
buffer around your set center
value that is equal to half its
setting. (ex. 1000ppm. Buffer

Press the up and down button sets a low CO
2
alarm. The alarm will sound and its icon will flash if
the sensor’s reading falls below the set CO
2

To activate the alarm, leave the alarm mode. The
alarm will turn OFF if the sensor’s reading rises
above the trigger or if any button is pressed. You
can also set the alarm OFF by holding the up and
down buttons together.
