BN-LINK Short Period Repeat Cycle Intermittent Timer, Interval Timer - Day, Night, or 24 Hour Operation, Photocell Light Sensor Dusk to Dawn for Hydroponics Aquaponics Aeroponics

Yes this timer is easy to use. It is not digital. It uses knobs which you turn to set the times ON and OFF. It will plug directly into an interior wall socket. Then you plug your device into the timer socket, set the ON / OFF durations and it works. The best part about this timer is how easy it is to set the times. It is like setting a wind-up kitchen timer instead of a digital timer. Turn the dials and done.

good simple design, plugs right into std outlet. simple to set run times and off times independently

I use these to time my return pumps. This allows me to run my emitters constantly without worry of the reservoir running dry or the return buckets over flowing. Turn the supply pump on and watch the return buckets fill up. Set the on and off timers to 15 minutes on the repeater. When the return buckets reach the desired level, plug the unit with the return pumps plugged into it, into an outlet. The unit starts with the on timer. When the level in the return buckets is just above the pumps lowest pick up level turn the on timer down slowly until it shuts the pumps off. Now watch the return buckets until the desired level is reached, then turn the off timer down until the pumps start. Check all the levels over the duration of the next few cycles and adjust as needed for the desired levels. It's that easy. The unit makes a click when it turns on and off. Other than that, it makes no noise. I have 2 of these products. I did get a bad one and Amazon replaced it within a few days. I do recommend these.

This review is for the BN-LINK Short Period Repeat Cycle Intermittent Timer, Interval Timer - Day, Night, or 24 Hour timer. Programing is a little confusing but works as it is supposed to. It would be nice if it had a manual override, because we use it for a 1.5 hp circulating pump serving ten DWC tables and also to hand-water potted plants (have hoses connected to the main supply lines for that). Also could use a little design improvement for the plug-in because it sticks up from the outlet and wobbles a tad bit. Won't fit into an outlet with a weatherproof cover but we knew that before ordering. Blocks two other outlets on a power strip (depending on the configuration of the power strip). Seems to be handling the work load so far. While you're redesigning maybe extend the times for on and off a little more.

Auto turns on with power up. So you can use it to limit the amount of time an alarm/device runs for. Would be even better if there was a 0 setting for the OFF setting.

I use this to operate a fan on my cold smoker to keep the sawdust smoldering. I Use it 20 seconds on and 60 second off. This timer allows me to let the smoker run unattended - I always had to baby-sit the thing to keep the sawdust smoking.

Works great

A must have for aeroponic clones. Works excellent and has never let me down yet
