Electronic Water Timer（YL21049）

• Frequency can be set at 1, 2, 3, 4, 6, 8, 12, 24, 48, 72 H, and Week
• Run Time can be set at 1, 3, 5, 10, 15, 20, 30, 60, 90, 120 mins
• Time Delay feature for easy setting of desired start watering time
• For taps with 26.5mm(G 3/4”) thread
• 2 x AAA alkaline batteries required(not included)

Why It Is the Easy Choice

• Two Turns, Then a Tap: Frequency dial = how often. Run Time dial = how long. Then press Delay to land the first soak on your preferred hour. That is the entire setup.
• The Delay Button Changes Everything: On plain two-dial timers the first watering lands hours after you set it. Here, hold Delay 3 seconds, then each press adds one hour of start delay — 8:00 am, 10:00 am, whenever you like.
• No Screen to Fail: With no LCD or app, there is nothing to misread, freeze, or forget. The most forgiving timer for beginners, kids in the garden, or a rental property.
• Tough Where It Counts: A sealed O-ring, tightened top cover, dirt-trapping filter, and water-resistant body shrug off rain, dust, and grit. Built to live outside.
• Honest Battery Alert: The LED blinks once every 4 seconds when healthy, and blinks fast or stays steady when it is time for fresh batteries. No nasty surprises mid-summer.

How It Works (Two Dials + One Clever Button)

• Frequency Dial: Choose how often to water: 1, 2, 3, 4, 6, 8, 12, 24, 48, 72 hours, or once a week.
• Run Time Dial: Choose how long each watering lasts: 1, 3, 5, 10, 15, 20, 30, 60, 90, or 120 minutes.
• Delay Button (the upgrade): Hold it 3 seconds until the LED stays ON, then press it once per hour of delay you want added to the start time. Two presses = water 2 hours later than now, every cycle.
• Need Water Now?: Turn the Run Time dial to ON for instant manual watering, then back to OFF when done — no reprogramming.

Built to Survive the Garden

• Hand-Tighten Fit: A 3/4" (G3/4, 26.5 mm) tap adaptor with a collar ring clamps on by hand — no spanner, no pliers, no cracked plastic.
• Snap-On Hose: A male snap-on connector at the bottom takes your standard hose or sprinkler in a click.
• Self-Cleaning Filter: An internal filter traps dirt particles and extends the timer life; just rinse it now and then.
• Weather-Wise: Water-resistant and happy from 1°C to 60°C water, 0–8 bar pressure. Mount it above ground and vertical to the tap — never submerged.

Perfect For

• First-time timer buyers who want zero learning curve
• Anyone who found a basic timer started watering at the wrong hour
• Holiday watering for lawns, pots, and veggie beds
• Greenhouses, allotments, and rental or Airbnb gardens

Heads-Up: This is a mechanical timer — brilliant in its simplicity, but it has no display or saved programs. One important rule: Frequency must always be longer than Run Time (e.g. you cannot set a 90-minute soak every single hour). The 2× AAA alkaline batteries are not included and should not be rechargeable. Use fresh cells at the start of each season.

Technical Specifications

Set It Up in Under a Minute

• Fit the Batteries: Slide out the battery compartment and insert 2 × fresh AAA alkaline batteries. Turn Run Time to ON briefly — you should hear the motor within 10 seconds — then back to OFF before connecting.
• Clamp to the Tap: Loosen the collar ring, screw the 3/4" tap adaptor onto your tap by hand, then lock it tight with the collar ring. No tools needed.
• Snap on the Hose: Click your hose or sprinkler onto the male snap-on connector at the bottom.
• Turn the Two Dials, Then Delay: Set Frequency (how often) and Run Time (how long). Hold Delay 3 seconds until the LED stays ON, then press it once per hour you want to push the start time. Wait ~3 seconds for the LED to confirm.

Good to Know: Changing the Frequency dial recalculates the next start time; changing Run Time does not. After any change, wait ~3 seconds (LED flashes quickly) for the timer to validate. In winter or freezing weather, remove the timer, drain it, take out the batteries, and store it indoors.

Questions Buyers Ask

Q: How is this different from a basic two-dial timer?

A: It has the same two dials, but adds a Delay button so you can set the exact start hour. No more working backwards from "first watering starts X hours later."

Q: How does the Delay button work?

A: Hold it about 3 seconds until the LED stays on, then each press adds one hour of delay to the start time. Two presses = water 2 hours later than now, repeating every cycle.

Q: Do I still just turn two dials?

A: Yes. Frequency = how often, Run Time = how long. The Delay button is optional — only use it if you want a specific start hour.

Q: How do I water right now without changing my settings?

A: Turn the Run Time dial to the ON position for instant manual watering, then back to OFF (or your usual setting) when finished.

Q: What batteries does it take?

A: Two AAA (LR03) 1.5V alkaline cells, not included. Use fresh alkaline batteries at the start of the season; do not use rechargeables.

Q: Will it fit my tap and hose?

A: The tap adaptor is a standard 3/4" (G3/4, 26.5 mm) thread with a hand-tightened collar ring, and the base has a male snap-on connector for a normal hose.

Q: Is it waterproof?

A: It is water-resistant for outdoor use, not submersible. Mount it above ground and vertical to the tap, keep the top cover and O-ring sealed, and never immerse it.
