Green Air Products has designed a complete line of atmospheric controllers.
We are certain one of them is right for you. They are designed to monitor
temperature and humidity, and operate fans, air conditioning, humidifiers,
dehumidifiers and misting systems etc. Our controls are mounted in brush
finish anodized aluminum housings which provide superior resistance to
corrosive humid atmospheres for years of dependable service. Illuminated
switches and function indicator lights mounted in a black housing with an
easy to read white dial face make our equipment an attractive addition to
your system. Green Air Products atmospheric controllers are designed to
easily plug into wall outlets or each other for easy installation. All controllers
are fully assembled and ready to use and no hard wiring is required. Green
Air Products uses only high quality UL listed components chosen to meet the
specialized needs of a greenhouse or grow room climate. Most of our
controllers are dual function and designed to work alone as an independent
control or connect to other controls to simultaneously coordinate other
functions.
The Hydro-Cycle Timer is our most recent development in timing control. The
Hydro-Cycle repeat cycle timer has solved the age old problem of accurate
short cycle timing. Perfect for plant zone environments, reptile habitats or
any other application requiring automatic short cycle switching. No
programming required. Easy to operate. Microprocessor time counter with
preset frequency and duration. The Hydro-Cycle timer has many uses. Only
a few of them include: fogging or misting, spray stakes or drip system timing,
air pumps, CO2 equipment and intake or exhaust fan control. The Hydro-
Cycle has a preset interval and cycle time. Interval is the time between the
“On” and "Off" cycles. The interval is preset for 4 minutes. Cycle is the length
of time that a specific function or condition must be maintained. Cycle is
preset for 60 seconds. Automatic reset feature allows function synchronizing
with other system controls. Unplug the power cord for manual operation.
The Hydro-Cycle timer utilizes a duplex cordcap which provides a combination
plug and receptacle power cord design. Operates on 120 volts AC with 15
amp switching capacity.

When plugged into the wall, as in the example above, the Hydro-Cycle will
perform the same timed operations indefinitely.The main nutrient pump is
plugged into the Hydro-Cycle duplex receptacle power cord. The nutrient is
scheduled to the grow system and drains into a catchment tank or directly
back into the main tank. The Cyclestat is ideal for aeroponics, misting systems,
foggers, spray stakes, drip emitters, ebb and flow or sprinklers.

The diagram above shows
how to install the Hydro-Cycle
to supply nutrient to a grow
system. The Hydro-Cycle may
be plugged directly into a
standard 110V wall outlet or
into another Green Air Products
timer or atmospheric controller.
IRRIGATION
CO2 ENRICHMENT
Here we describe a system by
which the Hydro-Cycle is timing
CO2 cycles (either emitters or
burner generators) which are
defeated at night by the
photosensor in the CT-DH-3P
atmospheric controller. CO2 is
also interrupted if an exhaust
function occurs and is
immediately replenished after
exhausting is completed.
