Reverse Day Light Fuge Lights

[lecher]

I'm just getting around to programing my new AC3 and I'm not sure what are the best command lines to use. I would like to have my fuge lights(LT3) to come on at 9:00PM and turn off at 10:30AM the next morning. It seems to me that if I use the "If Time >" statements, it wont work right.

You could do:

If Time > 21:00 Then LT3 ON
If Time > 10:30 Then LT3 OFF

or:

If Time > 00:00 Then LT1 OFF
If Time > 00:00 Then LT3 OFF
If Time > 10:30 Then DAY ON
If Time > 21:00 Then DAY OFF

If Timer DAY = ON Then LT1 ON
If Timer DAY = OFF Then LT3 ON

laurentm, In your first scenario 21:00 is > 10:30, so wouldn't that conflict? Not quite sure I follow the second scenario. What does LT1 have to do with anything? I'm also unclear on the DAY ON and DAY OFF. Forgive me if these questions seem stupid, I'm still feeling my way through this.

Thanks

No conflict in the first scenario, the controller will figure out the right cycle.

The second example was to show you the use of a dummy timer (DAY) to control both the main display lights and the refugium lights on a reverse cycle (DAY=ON for the main and DAY=OFF for the fuge).
