The CST-1P is perfectly suited to time CO2 enrichment for either CO2 generators or emitter systems. CO2 equipment is defeated during exhaust functions and immediately replenished upon completion. Photo sensor permits CO2 enrichment during day light periods only.

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.
