sorry rob when i wrote my question i was in a big hurry and didn't 
explain myself properly.
really i'm working on two different projects at the same time.
the first one controls a water sprinkeler system on the roof of the factory.
the idea here is to lightly spray a bit of water on the roof and then 
wait for it to evaperate.
i have two sprinkers up there now, on friday it was 95 degrees, the 
parts of the roof which i was watering hovered around 100 degrees the 
rest of the roof was anywhere between 130 and 145.
i was wanting to tap into the net to get the tempemater, humidity and 
wind speed.
seems like it would be more trouble than its worth though, i don't 
really think i want to have linux between me and my I/O board.  also 
with ms-dos and turbo c i can use any old computer we have laying 
around. the program and dos can fit on a floppy drive.

controlling the AC units is coming up as soon as i get finished 
installing all the sprinkers.
we have 8 ac units running 440 volts 3 phase at 65 amps. they are all

thermostatly controlled, i'm planning on  tapping into the termostat control lines with  relays.
the plan is to never have more than 6 units on at the same time.
theirs good reasons for trying this, almost half of our electric bill is base on "worst 15 minutes" of the month. in other words we had to pay 7000 dollars because on may 30 from 1:30 in the afternoon until 1:45 we "peaked for the month and used 750 kva of electricity.
i believe you dutch guys have a saying for that: "to gek".
if my math is right then 65 amps x 2 = 80 kva.
80 kva =  +- 760 dollars per month (at least thru july and aug)

hope i was alittle clearer without being to long winded.
thanks for the help.
