first variables
outlet 1 = metal Halide
outlet 2 = atinic
outlet 3 = skimmer
outlet 4 = chiller
outlet 5 = vortech
outlet 6 = heater
outlet 7 = return pump
outlet 8 = moon lights
then i program it the following
if time = 2 pm then turn on MH
if time = 10 pm then turn off MH
if time = 1pm turn on atinic
if time = 4pm turn off atinic
if time = 9pm turn on atinic
if time = 11pm turn off atinic
if time = 1045pm turn on moon lights
if time = 1245 am turn on atinics
if time = 0001am turn on skimmer
if time = 0000am turn off skimmer
if temp = 81 turn on chiller
if temp = 79 turn off chiller
if temp = 78 turn on heater
if temp = 79 turn off heater
these are just examples. not my real schedule. Just wanted to give you an idea. simple to program. I figure that you have so much dayam equip you would know how to use these things by now.
