The CST-1 has solved the age old problem of accurate short cycle tim-
ing. The only unit of it’s kind designed specifically for the control of
grow systems. Easy to set and operate. Solid state time counter with
adjustable frequency and duration. The CST-1 function timer has many
uses you will notice as you look thru this manual. Only a few of them
include: fogging or misting, spray stakes or drip system timing, air pumps,
CO2 equipment and intake \ exhaust fan control. Available with or with-
out photo sensor feature.

The CST-1S may be set for frequency and duration of timed events.
Frequency is the time between the “On” and "Off" cycles. The fre-
quency knob may be set from 7 minutes to 8 hours. Set this for desired
time between functions. Duration is the length of time that a specific
function or condition must be maintained. Duration may be set from 5
seconds to 30 minutes. Reset feature allows function synchronizing
with other system controls. Right side of timer operates short cycle
“On” times and left side outlets are “On” when right side is “Off”. This
feature provides an interesting variety of timing combinations. Oper-
ates on 110 VAC with 15 Amp switching capacity.

PERATE
This example shows the CST-1P being used to time CO2 production.
CO2 equipment is defeated during exhaust functions and immediately
replenished upon completion. Photo sensor permits CO2 enrichment dur-
ing day light periods only.

The diagram above shows how to install the CST-1 to supply nutrient to
a grow system. The CST-1 may be plugged directly into a standard 110
VAC wall outlet or into another Green Air Products Timer or Atmospheric
Controller. When plugged into the wall, as in the example above, the
CST-1 will perform the same timed operations indefinitely. The main
nutrient pump is plugged into the short cycle ( right ) side of the CST-1.
Nutrient is scheduled to the grow system and drains into catchment tank
or directly back into the main tank. The CST-1 is ideal for spray stakes,
drip emitters, ebb and flow or sprinklers.
