Tying Fans to Lights

jackers · 12/07/2012, 05:18 PM

This is probably a really easy one, so forgive me in advance.

I just installed some case fans to help keep my lights cool and my tank temps lower.

Can someone give me the code they recommend to turn them on with my lights?

Right now, I have this.
Fallback ON
If Temp > 77.0 Then ON
If Temp < 76.0 Then OFF

-----------------

My light outlets are called: Light2-Bulb or Light2-Bulb - (4_2)
Do I put that before or after my temp codes? How should it read? Like this?
If Light2-Bulb is ON, then ON

Do I have that right?

Fallback ON
If Outlet Lights = ON Then ON
If Outlet Lights = OFF Then OFF

The syntax is:

If Outlet Light2-Bulb = ON Then ON

Code:

Fallback ON 
If Temp > 77.0 Then ON 
If Temp < 76.0 Then OFF 
If Outlet Light2-Bulb = ON Then ON

This would operate the fans over the existing temp range when the lights are off. But, they would run continuously while the lights are on, regardless of temperature. Once the lights turn off, the fans will run until the Temp is less that 76.0
