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
zone is 1000-2000ppm).
