Tom,
If I understand you correctly, then I will be able to eliminate 16 syntax lines with a 2 pump operation?
I counted 10 lines (and 4 timers) that were not needed, but maybe I am overlooking something ? Anything with PM3, PM4, TM3 or TM4. These are the lines I saw as not being needed for 2 pump operation :
RND 10/10 ON/OFF Then TM3 ON
RND 20/10 ON/OFF Then TM4 ON
If Timer DAY = ON Then PM3 PF1
If Timer DAY = ON Then PM4 PF2
If Timer CHS = OFF Then TM3 OFF
If Timer CHS = OFF Then TM4 OFF
If Timer TM3 = ON Then PM3 PF3
If Timer TM4 = ON Then PM4 PF3
If Timer DAY = OFF Then PM3 PF4
If Timer DAY = OFF Then PM4 PF4
You still need all of your profile statements (PF1 - PF4), unless you don't need or want one of the 3 modes (IE: wave, chaotic or night). For two pumps it should look something like this :
Pmp Mode sD for PF1
Pmp Mode SD for PF2
Pmp Mode sd for PF3
Pmp Mode sd for PF4
Pmp Int 000/100 for PF1
Pmp Int 000/100 for PF2
Pmp Int 030/100 for PF3
Pmp Int 030/050 for PF4
Pmp OSC 13/13/00 for PF1
Pmp OSC 00/13/13 for PF2
Pmp OSC 05/20/15 for PF3
Pmp OSC 15/30/15 for PF4
If Time > 0900 Then DAY ON
If Time > 2100 Then DAY OFF
If Time > 1500 Then CHS ON
If Time > 1600 Then CHS OFF
RND 15/10 ON/OFF Then TM1 ON
RND 20/10 ON/OFF Then TM2 ON
If Timer DAY = ON Then PM1 PF1
If Timer DAY = ON Then PM2 PF2
If Timer CHS = OFF Then TM1 OFF
If Timer CHS = OFF Then TM2 OFF
If Timer TM1 = ON Then PM1 PF3
If Timer TM2 = ON Then PM2 PF3
If Timer DAY = OFF Then PM1 PF4
If Timer DAY = OFF Then PM2 PF4
And of course you could key off of an existing timer instead of using a separate one for DAY. I just have my DAY timer set to come on an hour after T5s and go on in the morning and go off (go into night mode) an hour before the T5s go off at night. Chaotic mode (CHS) comes on a hour or so after the halides come on in the afternoon. I do it this way with an hour "padding" to give the fish time to wake up before coming out of night mode and an hour in the evening to settle in with a lower flow pattern before complete lights out (I still need to put up the moonlight LEDs... one of these days I will get it done

). But if you are keying off of an existing lighting timer for day, chaotic and night mode then you can eliminate a couple of dedicated timers from the code above

. As I mentioned, we had the extra timers and I wanted the more granular control over the flow patterns and when each mode happened, so the dedicated timers were needed for that.
