Frequently Asked Questions
Do I need to turn off my controller to install a module?
No. Rain Bird expansion modules are hot-swappable, meaning you can install or remove them while the controller is powered on without interrupting your watering schedule.
Can I mix 3-station and 6-station modules?
Yes. The ESP-ME3 has three expansion slots that accept either module in any combination. For example, you could use two 6-station modules and one 3-station module for a total of 19 zones (4 base + 15).
How many stations can I add in total?
The ESP-ME3 base unit includes 4 stations. With three expansion slots, you can add up to 18 additional stations (three 6-station modules) for a maximum of 22 stations total.
