Program for Chiller

[Bullet]

Can someone help me with a program for my temp? I want to keep my temp at 80 deg. I have two fans inside my hood, a chiller, a fan over my sump, and two heaters. What would be the best program to use?

Thanks in advance for the help!

If Temp < 79.5 Then HTR ON
If Temp > 80.0 Then HTR OFF
If Temp > 79.0 Then FAN ON
If Temp < 78.5 Then FAN OFF
If Temp > 80.0 Then CHR ON
If Temp < 79.5 Then CHR OFF
Max Change 010 M Then HTR OFF

You can try something like this...
So..
The fan should come on before the chiller since fans are more energy efficient.

If temp > 79.5, then fan1 on
If temp > 79.5, then fan2 on
If temp > 80.1 then col on
If temp < 79, then col off
If temp < 79, then fan1 off
If temp < 79, then fan2 off
If temp < 78, then het on
If temp >78.9, then het off
You can adjust the highs and lows as you see fit, but that is pretty much all you need to do. That should keep your temps around 79-80 during the day and no lower than 78 at night.

I have my chiller port setup as a safety failover in case the controller on my JBJ fails. I just have the port on and if temps fall below 77.5 then turn off the chiller port.
