Had it hooked up for 3 days and the clock is already 5 minutes off ??? Its running too fast.
Can something in the code be adjusted to account for this?

Did you initially set the time?
The chip used is temperature compensated with internal high precision crystal. The controller syncs with that clock every hour.

yes the time/date was the first thing I setup..

I just changed it again and we will see what happens.


One more question.. Where in the code do I find the ATO set time range.. 255 seconds is not enough.. I'm using an aqualifter pump for ATO.

Heres what I used when I had an aqualifter.. You can change the port and also the time which I had at 1200 cause the aqualifter took forever

ReefAngel.SingleATO( true,Port2,1200,0 );

yeah I might just switch to the singleATO setup..
Does setting the 1200 there actually allow the ato set screen to go to 1200?? I thought there would be code somewhere to allow the ato set screen to go higher.

No it didn't change it on that screen. From what I have read that setting was depreciated in some of the code and memory location 276 is used for all.. I changed mine using that code but never looked at the setting.. Lol ..
Sorry I'm not much help.

Yeah, not on the screen
You will need to hard code it like dbmet posted.

Time is still running fast..
off approx. 90 seconds per day..
not so "high precision"

PM me if you would like to send it for repair.

I moved the AC power cords away from the serial cable/head unit and now the time seems to be running properly.. Seems you guys need a little better filtering (or filtering in general..I bet there is nothing)..
I also noticed I can move the power cords near the PH probe cable and the reading drops to 1 then creeps back up to 8.0 when the AC cords are moved away.

An alternating current in a wire creates an alternating magnetic field around the wire. To "filter" anything related to magnetism and cord placement would be a waste of time in my opinion..and would make the RA more costly.

For example...try placing a large magnetic item against anything electrical...it will cause errors to happen (LCDs, Radios, etc etc etc)...the RA is no different.

You would be talking about the RA to develop something to eliminate the magnetism from an AC cable? Simple...keep AC cables away...versus higher cost units...I mean it's not like I'd like to put my RA in and MRI machine or anything.

A few SMT ferrite beads, and other little tweaks, etc.. here and there is only going to add "pennies" if that to the total cost.
Proper filtering/design is what makes it a "professional" product.. NOT an expensive one.

Time and revamp sounds very affordable. Develop your own in my opinion. You have the idea. It's open source. Me, on the other hand, will just move my AC cords

I seem to be having the same issue although my headunit isnt around electric. Time was reset yesterday when I realized it was off and in 24hrs it is off by 3mins again. Any ideas?

What was the drift before you changed the time?

About 40mins

Also I have a ph reading a couple times a day of 0.00 maybe this is related?
