CST-1(P)
| CST-1The CST-1 has solved the age old problem of accurate short cycle timing. 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 and only a few of them include: fogging or misting, spray stakes or drip system timing, air pumps, CO2 equipment and intake \ exhaust fan control. |
| The CST-1 may be set for frequency and duration of timed events. Frequency is the time between the "On" and "Off" cycles. The frequency 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. Available with photo sensor to limit operation to daylight periods only (CST-1P) and\or built-in solenoid for emitter system timing (CST-1S). Operates on 110 VAC with 15 Amp switching capacity. |  Also available as a CST-1000. On times of 1000 minutes (16.66 hrs) and Off times of 1000 minutes. Often used to time lighting for cycles that do not necessarily correspond to normal 24 hour photoperiod cycles. For instance you might choose to run lights for 16 hrs on and then 6 hrs off and repeat this cycle. |
 | 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 catch tank or directly back into the main tank. The CST-1 is ideal for spray stakes, drip emitters, ebb and flow or sprinklers. |
| 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 during day light periods only. |  |
 | Here we have a timed intake / exhaust cycle with synchronized CO2 functions. CO2 equipment operates according to schedule set on CST-1P. Room air changes are registered according to CST-1 set points. CO2 is replenished immediately after exhaust functions and defeated during darkness periods. Reverse CST timers to defeat both CO2 and exhaust functions when light is not present. |
Plug the CST-1S into a 24 hr timer or Photoperiod Controller PC-1 for daytime function only or into CT-DH-3 for exhaust synchronized operation. Notice that this timer has the CO2 solenoid built right into it. The CO2 outlet hose can be directed into a circulation fan for even dispersion throughout the enclosure. |  |
