CST-1(P) Timer / frequency & duration


SKU: hmh00631 Category:


The CST-1P 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. It is easy to set up and operate. It is equipped with a solid-state time counter with adjustable frequency and duration. The CST-1P 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-1P 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. The 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.

This unit operates on 110V AC with 15 amp switching capacity.
