here is what she had before, also installed by me six months prior after her old one got struck by lightening. The ESP-LXME was the only rain bird controller that would handle as many zones as she has. So we installed it, but she is one of them people that likes to change zone times etc. frequently, and finally decided the timer was too hard to run. So we went this route, I have the old timer for sale if anyone is interested in it. It will handle 8-48 zones, and currently is equipped to handle 28.
