Could someone look this over?

Hi,
I just bought an AC3 and I am very nervous about running this program because I am not a code banger. Can someone please look this over for me and tell me if I need to add anything or change anything? Also in Ken's code I see If Power 015 Then MHD OFF, what does the Power 015 mean? Thanks in advance.

T5S$-A03
MHS$-A02
CAL#-A04
ALK#-A08
HET%-A05
FAN%-A06
ALM&-A09


If Time > 11:00 Then T5S ON
If Time > 22:15 Then T5S OFF
If Time > 12:00 Then MHS ON
If Time > 18:00 Then MHS OFF
Max Change 060 M Then MHS OFF
If Time > 1:00 Then CAL ON
If Time > 1:20 Then CAL OFF
If Time > 1:00 Then ALK ON
If Time > 1:20 Then ALK OFF
If Temp > 78.0 Then FAN ON
If Temp > 80.5 Then MHS OFF
If Temp < 77.0 Then FAN OFF
If Temp < 76.0 Then HET ON
If Temp > 76.5 Then HET OFF
If Temp < 73.0 Then HET OFF
If Time > 00:00 Then ALM OFF
If pH > 08.50 Then ALM ON
If pH < 07.80 Then ALM ON
If Temp < 75.5 Then ALM ON
If Temp > 80.0 Then ALM ON
If Power 000 Then ALM ON

Looks pretty good to me.

The Max Change of 60 is probably excessive. Most MH lamps only need 20-30 minutes cool down before then can fire again. But, thus is entirely your choice.

I suggest staggering the dosing periods... It is generally inadvisable to dose the Ca and alk supplements at the same time. Run them consecutively with a 30-minute gap in between rather than running them concurrently.

If Power 015 will delay the MH from coming back on for 15 minutes after a power outage. But you must have a 9v backup power source connected for the AC3 to detect a power event.

I think your high pH alarm setting is a bit high. Also, I'd suggest adding a failsafe line like If pH > 8.4 Then ALK OFF

Thanks RussM
