Customer Question

I have a international astronomic digital timer that is plugged into a Vista transformer for low voltage lighting. They impermissible new. I programmed it according to the instructions. When it comes on at dusk, only one of the sets of lights come on. The other two do not.
When I turn the timer on manually by pushing the on button on the timer, all three sets of lights come on.
I can't figure out why this is not working

Hello my name is ***** ***** I would like to try to help, May I have the model # of the timer please?

Expert:  Wayne Roberts replied 3 months ago.

If the timer has multiple out-puts this could happen, its easy to overlook programming nuances, possibly only "output 1" has been programmed?

Expert:  Wayne Roberts replied 3 months ago.

And the manual on arbitrarily controls all outputs

i am assuming all the lights are running off of one transformer?

Expert:  Wayne Roberts replied 3 months ago.

that is odd, if the transformer is feeding all three lights through one output..then they should all come on when energized...i am wondering if the light string connections are good. Is the light that comes on alone closest to the transformer in wiring?

Customer: replied 3 months ago.
I know, I am stumped too. No it is the farthest string.
Expert:  Wayne Roberts replied 3 months ago.

the obvious answer is somehow the two strings are defective, what make / model lights are they?
