If I lived near you I would wire that pressure switch up in a heart beat for you Mike! Just had to change my shurflo POS out for a real one, didnt take but a couple minutes and its actually a nicer setup :) This round I actually have my nozzles pointing up from the bottom of the root chamber. It seems to be working really well, and I can reposition them when they need it pretty easily. Since they are well below the roots, I think I will try a single soleniod and see how the run on is.

KDN that Arduino MPU unit is fantastic if a little overboard for a timer, your initial investment for the board plus extras to get it to the point where it could relay a solenoid and a pressure switch would probably be over a hundred I'm guessing.

Early someone was mentioning these SESTOS solid state timer units, offered on Ebay using OMRON relays inside, that are built in Hong Kong

He's offering them for $25

It seems if we're looking for a good timer on the cheap, the person early that actually mentioned this seller, was right on the head. The Arduino may I suggest seems as if it could replace a REEF KEEPER ELITE, which is a $600 dollar piece of equipment that I was planning to use to fully automate a garden but having seen the Arduino, it can do all those things and more.

Actually there's so many fields it could be applied to, air/heating/cooling/pool/spa/terrariums/coral/fish etc. It's actually asinine to comprehend just how much power one of those little units has plugged into the right equipment. :hump:

I can wire a pressure switch, I was simply saying that if I didn't, I'd need someone nice enough to come over & fill my acc manually. With the threat of catastrophe, I doubt I could find anybody. Lol, that's funny though. Thanks for the offer!

Yeah the Ardunio unit is quite amazing to say the least. It always impresses me and I am glad I started development with these things. The cost can be a bit high, but compared to what some of these commercial units cost is nothing. I have a little unit that is 2 relays and an atmega328 on it, it has most of the pins broken out for expansion, you can buy the unit for 35 bucks and time a pump/solendoid and light right from it plus have room for sensors or outputs. I also put an Atmega on a little pH interface design, I love this thing lol. I need to get a vid but I had it running a light and reading ph over bluetooth, with another couple pins you could break out :)

Ah crap late for work sigh...

I'll vouge for mike on the dig nozzles! Got mine in yesterday and there awesome. I have 2 girls and added a third last night keeping my fingers crossed. After discovering the issue pet flora had my drt-1 timer was not misting at night all set now though it's on 24/7 mode! I got the seato timer as well and need to wire it to see how well it works. I'll let u know

Anyone know much about the 422 timer as in wiring it up? I have the supply at 2 & 7 but for some reason I am getting no voltage reading at any of the contacts. I have a 120 volt ac timer and even set at 1 minute on and 1 minute off I get no voltage at any of the contacts, a bad timer perhaps? It cycles it seems but I'm at a loss as to how to wire up my selenoids if I can't get any ac voltage readings at the contacts.

I don't have a 422 but looking at the PDF I found on the net 2 & 7 are power for the timer not the load. Are you checking for voltage or continuity? Try checking for continuity on 1&3 or 8 & 9 during the "on" cycle. If you're getting continuity during the on cycle then just wire it as a switch for your (separate) solenoid power.

thx for the reply man.

i have power coming in at 2 & 7 but i only get 1/2 a volt at most off of any combination of terminals. i tried going from 1 to3 and 1 to 4 and also 8 to 5 and 8 to 6 and the most i get is .5 volts. i have continuity if i try it power less between 1 and 4 and also 8 and 5 . i assume if you feed it 120 volts ac it should be putting out 120 volts ac also. i even tried going from 3 to 4 and 5 to 6 in fact i tried every combination but still no voltage is coming through.

i have the timer set at 1 minute on the top and 1 minute on the bottom.

it's really puzzling and i think i may have a bad timer.

No, the 120VAC on 2 & 7 is to run the timer, you need a different power supply for the solenoids. Think of it as an automated switch. What voltage are your solenoids?

Here's a crude drawing of the wiring, if you want to use both contacts then attach the other wire to 6&8.

Here's my set up after removing the Rockwool from around them and cutting my mist times from 1 min on 2 off to 4sec on 3:30 off the one in the middle is showing some nice fuzzies:). I'm using the drt-1 timer for veg n cloning and recycling the nutrients back into the reservoir. I have 2 5gallons stacked on their own pump recycle RO water for the clones. The top bucket has 4 clone sites and drains back into the bottom bucket which is filled with RO water.

thi is with the dig nozzles my set up came with tefens but the digs perform better! I was just watching a you tube video tree fog aeroponics set up has the same nozzles i think there the best all around as far as mist and maintenance goes. but who knows im new to this but from what ive seen so far they seem the best....

This is off topic but,

There has been a lot of talk about DTW and home-brewed nutes on several forums. I literally have 1000's of lbs of dry chemical ferts that I will never use as I had to buy in bulk. If anyone is interested, pm me and I will mix dry batches for cheap. I hope Im not opening Pandora's box, but Im willing to help out where I can.

I have the 12volt version, and I use a single source for power to the timer & solenoids. If your solenoids are 12 volts, I guess bridging wouldn't work for ya. Sorry.

oh damn i didn't realize that. well now it makes perfect sense and it will be fine. many thanks amigo. i thought the 422 powered through the contacts. it does work then because i tested it with continuity, now that i know there is no voltage at the contacts. :D
