The Harvest Master range of climate controllers make life easier and safer. They give you more control over pretty much every aspect of your grow room and as a result, you can expect to increase your yields.

CO2 EASi' Controller (with CO2 Sensing)

Operating the CO2 Easi is simple, the CO2 EASi is an intelligent control system that takes care of CO2 and at the same time is an intelligent Temperature Controller when the COOL KIT is attached.

Light ON periods (Day):

The controller will try to maintain the pre-defined max. CO2 PPM for the longest duration. It aggressively maintains the CO2 at and just above your target ppm value. But simply injecting CO2 is not that straight forward. CO2 is a greenhouse gas and will raise the temperature in the room, so the CO2 Easi has been designed to use the COOL output to try to keep temp within 2’C/F of the Target Temperature (say 25’C/75’F +/-2'C/F). If the temp rises too high (or there is no COOL unit), the FANS are activated at the pre-set Max Temp, as standard at around 32’C/90’F.

Light OFF periods (night):

The controller does not need to maintain CO2 levels because the plants are asleep. For temperature control the system automatically uses FANS as the cooling control, but will use COOL output if the temp stays high or gets too high due to external influences (as when the outside air being drawn in is from a hot environment as in the summer months)

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! This is a unique feature to the Harvest Master range

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 organised.
