What makes the Holman CO1609 different from a standard tap timer?
Can I use the CO1609 for a greenhouse?
Product Description
The Holman CO1609 Misting Tap Timer provides automatic control for misting systems, greenhouses, vertical gardens and other applications requiring short, repeated watering intervals.
Unlike a standard tap timer, the CO1609 is designed specifically for cyclical misting, allowing you to set a START TIME and STOP TIME and then control how long the water remains ON and OFF during that period.
For example, you can program the timer to start at 6:00 am, run the misting system for 5 seconds, stop for 40 seconds, and continue repeating this cycle until the programmed stop time.
The timer supports watering intervals in seconds, minutes and hours, providing the precision needed for misting applications and greenhouse watering. It can also be operated automatically or manually when required.
