Need help with Jr and sun command

[Lukel]

hey i use the sun command to run my halides, and my atinics, for eg:
if sun 000/000
then lt1 on

if sun 030/015
then lt2 on

lt1 being atitics an lt2 being halides, how do i get the atitcs to shut off for the duration of the halids, (i only want atitics before and after halides with 15 min overlap)

is this even possible???

I am not an expert on the ACjr but looking at the online manual, the following should shut the actinics off when the halides are on. Although, this won't give you any overlap:

If Timer lt2 = ON Then lt1 OFF

That would work.... but then i wouldn't get my 15 minute overlap that the Halides need to fire up...

If there is not a limit to the offset, you could use two sun commands for the actinics (assuming 8hr photoperiod):

If sun 000/480 then lt1 on
If sun 480/000 then lt1 on

The limit on the Jr is 240 (if I remember correctly).

If your halides need time to wam up then you have few options; the best way I can think of would be to use a virtual outlet that uses SUN command, offset large enough to allow halides to come online and to use that virtual outlet to turn off LT1.

About the same as the original reply but with extra time by using the virtual timer. This is assuming you have a spare timer slot; the Jr can only support 12 timers total.

so it would look something like
if sun 000/000
then lt1 on

if sun 030/-015
then lt2 on

if sun 045/-030
then (virtual outlet) on

if (virtual outlet) on
then lt1 off

something like that???

Yes, that is correct and something to keep in mind; order is important; the 'if virtual blah blah' MUST come after the 'If Sun ... LT1'
