New Setup - Converting from RainDial

post by jeremysm1 on Oct 17, 2016

Hi Everyone,

I’m ready to jump into the new tech age of technology irrigation. I currently have a RainDial 6-zone unit (RD600-EXT-R) and want to get up and running. I’m in Scottsdale, AZ if that matters. I think I’ll need the following:

1. Rachio 8-zone
2. Waterproof enclosure
3. Flow Sensor

Sound about right? Any suggestions as to which flow sensor works the best or is most cost effective?

Hi @jeremysm1 !

Super excited to have you join the team! Sounds about right if you are installing outside! The only thing I will say is getting a flow sensor is definitely optional. Depending on your needs, I would say there are probably some more cost and time effective ways to get accurate usage from your app. This community is excellent in helping with getting that done!

Welcome @jeremysm1. I’m in north phoenix. I have 5 zones on my system so I went with the 8 zone Rachio. Sounds like you should get the 8 zone system unless you have plans for any type of renovation of your irrigation system. Also you’ll want an enclosure if it’s outside. I’ve had mine for 1 full summer facing the southern sun and it’s working great, so far no worries with heat as long as it’s within a box.

Thanks for the welcome messages! I ordered the Rachio and enclosure today but will hold off on adding the flow sensor after feeling out the system for a little while. I’m going to shoot for installation over the weekend–so keep an eye out for my frantic posts then.

I hope you love your Rachio as much as I do, @jeremysm1! I also do not have a flow sensor. I may install one some time in the future as I travel a lot and can’t always monitor my yard. (And with all the traveling I do, I have been very pleased with how my yard looks when I get home, and that I can monitor what’s going on at home from anywhere in the world!)

Got the Rachio in the mail. Here is a pic of my current RainDial. Is this a simple unplug from here and plug into the Rachio setup?

Also, my electricity is piped into the RainDial on the right side, but needs to be on the left for the Rachio. Since it’s a flex cable, that should be easy enough. But I’m no electrical expert, is it the same cables/power for RainDial as the Rachio? I’m assuming that I just need to shut off the breaker box before playing with the electricity, right?

@jeremysm1 I’m no electrician, no landscaper, and no Rachio employee, but I’ll try to help you as best as I can! Your Irritrol controller and setup on the wall is as same as mine was. I converted to a Gen 1 Rachio… not sure what you got. But your zone wires on the bottom will just go into the appropriate zone plugins on the Rachio.

My first test is complete, and the Rachio worked! I’m a little baffled that I actually got my system converted from the RainDial to the Rachio on the first try. Okay, so walking around the yard, turning on/off the zones one by one I found this to be the setup:

• Zone 1, Zone 7, Zone 8: blank / not used / not wired (followed the RainDial setup for zones)
• Zone 2: all of the bigger trees seem to be on this zone. Most have red emitters.
• Zone 3: seems like everything in the backyard (except the bigger trees) are on this. Vines, bushes, shrubs, plants.
• Zone 4: all I could find turning on is 1 emitter for a plant near the garbage cans.
• Zone 5: the entire front of the house (except bigger trees)
• Zone 6: all I could find is 1 small 4ft tree in front…nothing else on this

@jeremysm1 I encourage you to look at the ‘Water Use It Wisely’ site as a great orientation to how your drip zones should be configured, and how much and how often you should water your plants.

I finally was able to go through that link in order to confirm/find the soil type. Here are the items that I think we’re looking for:

Momoli gravelly sandy loam, 1 to 5 percent slopes. Rating 0.08

Typical profile

• A - 0 to 3 inches: gravelly sandy loam
• Bw - 3 to 60 inches: very gravelly sandy loam

Please let me know your thoughts and next steps. Thanks!

So for Soil, you can set it to something like “Sandy Loam”, but then go into advanced settings and change your ‘Available Water’ (AW) to 0.08. The lower this number, the more sandy the soil is. Sandier soil allows water to flow thru it faster, but it also does not hold onto water as long as clay-type soils.

Those settings make sense. I updated the zone setting accordingly. Some questions:

1. In the advanced, there are settings for Area, Root Depth, Allowed Depletion (ie 50%), Efficiency (90%) and Crop Coefficient (75%). Do I just leave these alone?
2. Regarding the Area from question above, how do I calculate? I’m assuming it’s generalizing the qty of emitters based on the area, is that right? I don’t have lawn, so everything is shrubs/vines/trees. How would I change that to reflect the amount of emitters?

Area: This has no impact on your watering and is used only by Rachio to give you an estimated amount of water used. To be honest, I wouldn’t even mess with this out of the box. Once you feel comfortable that your Rachio is watering your yard correctly, then you can play around with this setting.

Can you describe the Flex Daily setting? Does it take into account my weather, season, and water requirements based on the settings we setup for each zone? Do you know when it’s scheduled to water and for how much or do you just read the logs? Thanks!
