Some stuff is ok.
Controllers without instructions are quite common. They are advertised to come with wiring diagrams. Ha. Ha.
I found a generic wiring diagram here on endless sphere.
I won seven dollars by opening a dispute with Green time. I would rather have the promised wiring diagram.
I NEVER got the seven dollar refund.
Lots of trial and error to hook up.
Next time LYEN for sure.
No amount of Emails had any effect.
Contacting the customer Complaint part of ali baba (the 40 thieves company) got some subdued effort from Greentime mostly to stall while the deadline for complaining was running out. Too much bother for nothing.
