• Highly useful for turning ON and OFF at regular intervals. Other recycling timers are inaccurate or do not allow for precise settings … CHRONO-R4 is capable of accurate settings from 96 hours down to ONE second!
• CHRONO-R4, is actually TWO separate recycling timers with 4 timer settings connecting to FOUR individual outlets. The recycling timer has two ON and OFF settings, (Timer #1 and Timer #2) capable of controlling a pair of outlets (receptacles).
• CHRONO-R4 is designed to activate any device (pumps, fans, lights etc) at precise intervals. The user selects whether the timer is to function during the day, night or 24-hours a day, and the photocell built into the unit automatically responds.
• CHRONO-R4 contains unique “normally-open and normally-closed” relay connections that allow the grower to use the recycling timer as a “flip-flop” timer. This means the unit allows for two banks of lights to operate on opposite schedules.
• For complete customization CHRONO-R4 allows the user to select how the timer reacts when power is interrupted.

All of the settings for the CHRONO-R4 are easy to access using the simple push-buttons on the front of the unit. A 15-amp circuit breaker and heavy-duty internal construction ensures that the unit will operate for years without fail. We only use high-quality UL / CE listed components.
