How to program your Melnor Hydrologic Water Timer

How to program your Melnor Hydrologic Electronic water timer. You can use this guide for the 1-4 zone models as the programming is the same. I show the whole manual in the video as well.
Having an automatic water timer is super convenient and I 100% recommend it for watering the garden or the lawn.

Thanks Mike. I did a quick search for instructions and your video was the only useful video on how to set the unit up.

[@mosesmegalli856]

here I am again almost a year later getting some help from your video to program a new water timer. thank you very much sir.

[@ginfonte3386]

Thanks for this video!! I used this timer last summer, but when I went to set it up this spring I couldn't find the manual and didn't remember everything. Panic!. When I replaced the batteries, the memory had stored what I did last year !! Great unit!! But your help has me in the driver's seat again. Thanks too for showing a copy of the manual.

You made easy what starring at the instructions couldn’t do. Mahalo Mike!

[@tonyholmes9024]

Thank you for the video!! I was having a hard time programming four zones!!

[@mikesyarden3187]

no problem. It took me a while to figure it out. Glad this helped. Thank you

[@suekardon9564]

Thank you! My landscaper put in the timer and walked off with the instruction manual so this was perfect!!

[@mikesyarden3187]

Glad I could help :)

Glad it helped!

[@Rosewolf29]

my dad got one similar to this but it was only two zones and I programmed it for him but it only ran the first cycle but not the second one. After watching this, I think I figured it out XD thank you

[@mikesyarden3187]

You're welcome :)

[@jeffhowell3911]

Very well taught

Zone 1 he set to water mon and wed, but then set to every 1 day.....which said was to water everyday. Confused?

[@trlax31]

Awesome video!

[@NancyMurray-ke7zc]

How do i deselect a zone!! My unit has 3 zones but i only want two!! Can't figure out how to delete a zone!! Help

[@camstojkovski9844]

Mine during the water day option does not give days of the week. The screen on mine is different than yours on time 1:45. Anyone have any ideas why?

[@pdaddybml]

Amazing. Ty

[@mikesyarden3187]

You're welcome

[@mosesmegalli856]

thanks very much. it was puzzling me. unfortunately this device cannot handle a bit of high water pressure. other than that it is perfect. I wonder what would be the alternative?

[@mikesyarden3187]

you're welcome. How high is your water pressure? because a standard home in north america is about 50-60 PSI. anything higher can stress you plumbing, and possibly cause damage to other parts in your home.

[@mosesmegalli856]

@@mikesyarden3187 I have a well with a 2 hp water pump for irrigation 3 acres of the backyard. Unfortunately, the Melnor Water Timer couldn't handle the pressure, it was not able to shut the water back off. other than that it is a great product.

[@mikesyarden3187]

@@mosesmegalli856 oh wow. the pressure from that must be really high.

[@akawedgeify]

Add a drip 25psi pressure adapter tube $6 black plastic from HomeD. before timer.

[@joysanders9315]

I have an older model that does not have a "cycle" button. It's a 2 zone. How would I set that to water twice each day? Help!

[@joannbishop892]

My time changes from regular time to army time.. I've had one of these for two or three years, and it has never done that before. How do I get it to stay on regular time?

[@sharongarland3678]

Mike, got it set up seems to be working. My problem is how do I pair it to my phone so I can watch it on my phone rather than running out here looking at the timer

[@mikesyarden3187]

You cannot pair this model with your phone

[@ziongivinggarden]

How often do you have to change the batteries? Using one of these in our community garden.

[@mikesyarden3187]

I used mine for 2 summer seasons (May-Sept) with the same energizer double AA batteries. But it will depend how often the unit is watering and the quality of the batteries.

[@shawnledoux2000]

Great video. Is there a way to turn off cycles? For example I had cycle A and cycle B programmed but now I only want cycle A to run and not cycle B.

[@vbrownmt]

I'm having the same problem. I used this last year on 3 zones and now I want 2 zones and when I hook it up the 2 would cycle when set but the two not set just gush out water. I've tried to set it 3 times.

[@KarpioHugh]

I'm confused with the every (1) day... it's kinda confusing I want it to water everyday... is it supposed to be set at 1 or 7 🤔

[@mikesyarden3187]

It is a bit confusing. it is suppose to be set at 1 (every day), if you set it to 7 it will water every 7 days (once a week)

[@KarpioHugh]

@@mikesyarden3187 thank you so much... i changed it to 1 and hopefully it waters everyday

[@Gnano]

Your videos awesome, thank you.
