Review: Great product and easy to install! - Worked well in my 15-year-old Rain-Bird ESP Modular. Took only 2 min to replace the faulty Expansion Module.
Review: Good price, fast delivery and easy install. - Good price, fast delivery and easy install for an 2014 esp-me. 3 zones on our system went out. On manual cycle, one channel reports no error, while the other two would start the cycle, blink twice then report nomod. I further confirmed with a meter, with and without channel wires connected, that there were no 24V AC readings on any of the three channels when command to turn on. I went as far as moving the module to another empty slot and repeated the measurements. At this point, I’m pretty certain that the module is dead. The new module came quickly and simply screw down 3 channel wires, slide in the module and flip the lock lever!
