The operation of CO 2 EASi.



In Light ON periods (Day):
The controller will try to maintain Max co 2 high PPM for the longest duration. It aggressively maintains the CO 2 at and just above your target ppm value.

It will use COOL output to try to keep temp within 2'C/F of the Target Temperature (say 25'C/75'F).
If the temp rises too high (or there is no COOL unit), the FANS are activated at Max Temp, say 32'C/90'F.

In Lights OFF (night) periods:
The controller does not need to maintain CO 2 levels.
For temperature control, automatically uses FANS as the cooling control, but will use COOL output if the temp stays/gets too high (as when the outside air being drawn in is from very hot outside)

Efficiency Monitoring.
On the display, you will see the “Efficiency % monitor” .
This unique Harvest Master feature is calculating how efficiently your room is operating!

• If FANS are activated, this is “wasted CO2 ”, reducing the efficiency.
• If COOL is activated, 99% efficiency is possible.

If you have been achieving high efficiency, but suddenly see a low efficiency rating, are;
• Door seals ok?
• CO2 device operating properly?
• Cooling unit operating OK?
What is wrong, that you may not have noticed otherwise!

Usage monitoring.
CO2 EASi has a “CO2 bottle life” timer.
Another unique Harvest Master feature!
• When emptied, select “New Tank” to reset the timer.
• Shows “% of Last tank used”, so you know to get a new tank organized.
