I disagree on the demand... most people, especially those that run controllers, do some sort of dosing (an ATO is a form of dosing). Also, manually dosing sodium bicarb or whatever one uses for alkalinity is risky business with high demand unless one is willing to dose multiple times per day. Look a...

Thanks for the pics. I can't really follow all of the wiring but at least I think I understand what I need to do. This isn’t an uncommon problem with controllers and programmable dosing pumps as a quick search will find all sorts of situations where dosing has gone amuck. In fact, I'm surprised some...

tngo wrote:They should have 12V DC versions also if you go that route.

That is exactly what I would want. However, I also have to be able to connect to it and have seen nothing that I would know how to connect male/female DC connectors to.

I'm not sure how your DC module works but if its reliant on the power expansion relays to power on and off at certain times then the time delay relay should work. The power expansion relay will supply power to the time delay relay which would supply power to your DC module. The time delay relay has...

Bump.

I use a time delay relay as a failsafe for any type of dosing especially if it's a concentrated solution. These will be independent of any controller to create a maximum time a relay can be switched on. Roberto pointed me to https://www.ebay.com/p/16012060306?iid=381936974053 previously but there a...

My kalk stirrer's dosing pump turned-on for no reason and ran longer than what is in memory. Luckily, I was by the tank and turned off. The dosing pump runs off a D/C powermodule. I don't know if these "stick", but I was able to turn-off via the Uapp. Initially, when I went back to "A...

if ( hour(now()) >= 1 && hour(now()) <= 4 ) ReefAngel.Relay.Off( Box1_Port1 ); Thanks! So the syntax for the logical function "and" is: <space>&&<space>, correct? Also, my pH Expansion has dropped out a couple of times, showing a pH of 0.00. Since 0.00 is lower than my Int...

rimai wrote:Yes you can use and and on your if statement.
Just make sure to add that line after your CO2Control function.

Great. What is the syntax for using “and” when linking two if/then statements?

Oops... I just realized that my if/then statement code won't work without "and". Can you include an "and" in the if/then statement code?

To better balance my daily alkalinity, I'm interested in turning off my Carbondoser (fancy solenoid connected to CO2 tank for my Ca reactor) for a few hours in the middle of the night. The problem is, this relay/port is already set for CO2 control, tied to the pH read by my PH Expansion module ReefA...

rimai wrote:The code you used looks fine.

Thanks!

I used the CO2 control code below, and that appears to work... meaning it recognizes the 'on' value as all three ports default "auto" on with my pH well over 7.85. However, I don't know if they will shut-off at a pH of 7.75 ReefAngel.CO2Control( Box1_Port1,775,785 ); //Turns off Carbon Dos...

If you are not using it, remove it. But the issue you are having still is a mystery. It should work as you posted. I am not understanding why it is not. I removed it but same thing... all three ports are "auto" off. Also, this is the code that allows all 3 ports to default to "auto&q...

Why do you have RANet on your code then? Good question. I'm not sure what RA Net is, but my original code was on a RA+ with Cloud wifi. I then migrated to RA* and use the ethernet connection. I do most programming with the Web Wizard and then a little code I've gotten help with. Now, I also run a D...

rimai wrote:Are they on the RANet or USB connected relay boxes?

Both boxes. 2 on an Expansion Box, and 1 on my old original box with a serial cable (looks like a serial cable).

Yes, a couple of "//" in front of each one, and they are all on. I even changed one to < only (no =), and they were all still off. I wondered if they needed a > statement as well, but I've never noticed having to do that.

I just added my Ca Reactor and was adding code to shut it down if tank pH (not Expansion pH) gets below 7.75. Even though my pH is well above that, the ports turn-off immediately once code is loaded and even after a second reboot. I verified it was these statements by remming them out. What am I mis...

rimai wrote:It is always based on midnight.

Ok, so unless I decide to run only during a specified time, all I need to add is the basic dosing code like that generated in the Webwizard, correct?

I want to stop running kalk via my ATO and start dosing instead. I can get the code for repeating and offset times from the Webwizard, but I don't understand how to identify a starting time or if there is just a default. I plan to dose every 60 minutes with no offset (using internal memory values), ...

One other question. My light fans are 12vdc, but the manufacturer of my light fixture (ATI) recommends running the fans at 9vdc to preserve them (the fixture comes with a converter where you can switch between different voltages). They also state that running at 10vdc would provide a little more coo...

Thanks Roberto! I have two other Expansion boxes (Star Controller), so I've set the dip switches on the Power Expansion to "Box 3". Is that ok? I found the ports labeled on the board (J1, J2,... J8) so I guess I've got that. Regarding voltages, do I need to try to find specs on everything ...

I've had a Power Control Expansion for awhile and am now ready to install but have some questions: 1. The old manual says to download test code, but I've also read you just have to set the dip switches then reference the box and port #'s in your code. Is referencing the Box and port #'s all you have...

Just getting a chance to get back to this. When I did a standalone compile, no errors. However, when I uploaded, the compile portion gave me these errors: Compiling code for RA_STAR board Number of Relay Expansion Modules: 2 Relay Expansion Module Dimming Signal Water Level Expansion Module Reef Ang...

If you copy just make sure you paste on setup() section and not loop()

Cool... thanks!

Yes you usually upload the whole file but that's for the RA+. I would think it's the same for the RA* but it might be a different initial code and a different line number but should be labeled the same. I started with the Plus and then went to the Star. The file date on the InitialInternalMemory fi...

Thanks I might try that. I wonder why the my delay doesn't work? I mean that would be the perfect solution? I'm pretty sure I ran into the same thing, which is why I have the code I have. I just tried putting values in the Delayed On field, and the generated code is exactly the same whether you put...

Thanks for responding, but I'm not sure where to find the Initial Setup Code. I have a good understanding of the normal sketch stuff but have only a very basic understanding of the libraries and will need a good bit of hand holding to go that route. I decided to reword my request and post in the &q...
