Control Screen Porch Misting System vis the ISY

[jmed999]

I'm going to install a misting system on my screened in porch and I'd like to control it with the ISY. I'm looking for ideas on how to do that. This is the system I'm installing...

It connects to a garden hose but I may connect it to pex and run the pex inside a column and into my crawl space. There I could connect it to the cold water pex line under my house.

 

Since this is not a pricey project I'm looking for an inexpensive way to turn it on and off.

 

Any ideas?

 

Thanks!

Jmed999,

 

You can install a powered water valve on the incoming supply for your misting system and then use and I/O Linc to control the control voltage for the valve. The ISY can then control this buy adding time or temperature to the conditional if you like.

Thanks for your help!

 

My only concern is this controller isn't rated for outdoor use. It would be located in my crawl space which gets very humid. What type valve would work in this scenario? Do you have a link?

 

Thanks again!

Since I have one of these...

for my irrigation system with a couple unused zones, I may use a sprinkler valve and an unused zone to control the mist system. Basically zone 6 would be the mist system and I could control it with a remotelinc. Adding a zone/valve could be a pain though. The good thing is the pipe would be in ground thus no worry about freezing here if in ground.

 

Would this work? Am I missing anything?

 

Thanks!

All seems reasonable to me. Make sure you use potable water for the mister (I know some areas have a secondary non-potable supply for irrigation needs), and a check valve if code requires!

Keep in mind that the EZFlora only allows one active output at any given time. This may or may not be a problem depending on if you run irrigation timers when you also expect to be using the mister.

 

Take a look at the On/Off Outdoor Module.

 

Couple it with a 110 volt Solenoid. Or a 24v transformer.

Well you got me thinking.... I believe I will use these...

I already have a zwave mesh in the crawl space so I think this will work fine connected to my cold water pex line. I will also use a check valve and other appropriate fittings.

 

With this setup the only thing I need is a transformer for the 12V solenoid valve. I'm not sure how many mA that thing will need though. Any suggestions on a transformer?

 

Thanks guys!

I have a box full of old DC power supplies. You may have one just sitting around the house. The 24 volt ones not so much, but 12 volt is in the range of common.

If you are going Z-Wave you may look at this too. I've not used one though. I thought you were concerned about environmental exposure? The outlet you linked is not a GFCI outlet and only one of the plugs are controlled.

[jmed999]

I do have some 12 v transformers sitting around that I could use. Does it depend on the amps of the solenoid valve or will any work? Sorry but my electrical knowledge isn't sharp in this area.

 

Thanks for your help!

I only need one plug to be controlled. The outlet is going in a GFCI circuit. The surrounding conditions in the crawl space can get pretty humid but it doesn't see extreme temps. If it fails due to being in the crawls space I could always use an outdoor module like the one in your link. Do you think it will work fine?

This one is the same price but you could just use the 110 outlet without any transformer.

 

As for the 12 vdc one you linked earlier, it does not really give much information to go on for that. Similar china types take 3 amp starting and 2 amp constant. Higher quality ones can get below 1 amps though.
