Instruction manual is very confusing and poorly written
the instructions are obviously written by someone whose first language is NOT english. There are things in the instructions that do not correspond to the unit, I have spent two days trying to get the system to operate. The instructions are poorly written and confusing as they often do not correspond to the read out of the controller. Price is right and the controller is certainly able to do what I need but with the poor instructions it is a crap shoot.
