So, this is my 2nd AC3, being set up to run my frag system. My main one is tried and true, been running the tank for 2 years. I basically copied and modified my program from the main tank for this tank. It worked great all day yesterday, then I started having issues with the temp jumping around last night (probe is brand new, been used 1 day), and then this morning, my lights start firing off on their own, an hour before the first one is supposed to come on. I force it off with manual off, it doesn't listen. I unplug it and then plug it back in to the DC8 and it goes out, I then unplugged and reset the AC3 thinking that may be the issue. No luck, now lights all show UNK for state, and the first one didn't come on when it should have. Any ideas, do I need to reinstall the firmware already?!? Thanks in advance for any help/ideas.

Here's the program:
MH1$-A01
MH2$-A02
MH3$-A03
AT1$-A04
FAN&-A05
COL%-B01
HET%-B02
ALM&-A09

If Time > 07:30 Then AT1 ON
If Time > 22:00 Then AT1 OFF
If Time > 08:30 Then MH1 ON
If Time > 19:30 Then MH1 OFF
If Time > 09:30 Then MH2 ON
If Time > 20:30 Then MH2 OFF
If Time > 10:30 Then MH3 ON
If Time > 21:30 Then MH3 OFF
If Temp > 78.5 Then COL ON
If Temp < 78.0 Then COL OFF
If Temp > 84.0 Then COL OFF
If Temp < 77.5 Then HET ON
If Temp > 78.0 Then HET OFF
If Temp < 73.0 Then HET OFF
Max Change 015 M Then COL OFF
Max Change 030 M Then MH1 OFF
Max Change 015 M Then MH2 OFF
Max Change 015 M Then MH3 OFF
OSC 010/050 ON/OFF Then FAN ON
If Timer AT1 = OFF Then FAN OFF
If Time > 00:00 Then ALM OFF
If Temp < 74.5 Then ALM ON
If Temp > 80.3 Then ALM ON

This looks very similar to what I reported to neptune

Please refer to

for my program. I eventually just removed the max change statement for the mh light. Most mh ballast will automatically not start up if it has recently been turned off.

Interesting, thanks for the tip. I will pull the max change statements at lunch when I go home and see if that fixes it. Come to think of it, I believe I did add them last night, after the lights were already on and going for the day.

I have the same logic in my other AC3 and have never had a problem, but the statements do come after the If Temp > xx statement like what you showed in the example on your thread of how it should be set up.

Just to update, this seemed to fix the issue for me as well. Thanks again for the info.
