Okay get ready for it... AHHHHHH! I'll add some notes to say what everything does.

PUM#-A01 -------- Main return pump
LT1$-A02 ---------- Metal halide
LT2$-A03 --------- Metal halide
CO2&-A05 -------- CO2 solenoid for calcium reactor
COL%-A06 ---------- Cooling fan
KAL#-A07 -------- Kalk reactor mixing pump
ALM&-A08 ------- Audible, email and text alarm
LT3$-A09 --------- Refugium light
HET%-A10 -------- Heater
SKM#-A11 -------- Protein skimmer feed pump
ATO#-A13 -------- Tunze Osmolator auto top off

(so that lights have time to cool after a power interruption)
If Power 020 Then LT1 OFF
If Power 020 Then LT2 OFF

(defaults)
If Time > 00:00 Then PUM ON
If Time > 00:00 Then ALM OFF
If Time > 00:00 Then ATO ON
If Time > 00:00 Then SKM ON

(so that lights and tank have time to cool if tank gets too warm and controller shuts off lights)
Max Change 020 M Then LT1 OFF
Max Change 020 M Then LT2 OFF

(seasonal lighting control)
If Sun 000/-120 Then LT1 ON
If Sun 060/-060 Then LT2 ON

(reverse lighting for refugium light)
If Sun 000/-060 Then LT3 OFF

(seasonal cooling and heating control)
If Temp > RT+1.8 Then COL ON
If Temp < RT+1.5 Then COL OFF
If Temp < RT+1.2 Then HET ON
If Temp > RT+1.5 Then HET OFF

(safety precautions in case tank becomes to warm or too cold)
If Temp > RT+3.5 Then LT1 OFF
If Temp > RT+3.5 Then LT2 OFF
If Temp > RT+3.5 Then ALM ON
If Temp < RT+-0.5 Then ALM ON

(in case of temperature probe failure)
If Temp < RT+-9.9 Then HET OFF

(kalk reactor mixing pump mixes for 5 minutes 4 times a day)
OSC 005/255 ON/OFF Then KAL OFF

(calcium reactor pH control)
If pH2 > 06.60 Then CO2 ON
If pH2 < 06.50 Then CO2 OFF

(tank pH control)
If pH < 07.60 Then CO2 OFF
If pH < 07.60 Then ALM ON
If pH > 08.40 Then ALM ON
If pH > 08.30 Then ATO OFF

(water on the floor sensor: open means dry and closed means wet)
If Switch1 OPEN Then PUM ON
If Switch1 OPEN Then SKM ON
If Switch1 CLOSED Then SKM OFF
If Switch1 CLOSED Then PUM OFF
If Switch1 CLOSED Then ATO OFF
If Switch1 CLOSED Then ALM ON

(I have a single overflow hole in my tank so I have a switch mounted on the rim to stop potential overflows onto the floor. Open means the water level is too high and closed means everything is fine)
If Switch2 OPEN Then PUM OFF
If Switch2 CLOSED Then PUM ON
If Switch2 OPEN Then ALM ON




Any questions?
