Frequently Asked Questions

Is Rain Bird ESP-SM3 the same as ESPSM3?
Yes. ESP-SM3, ESPSM3, and MFG# F38200 are the same 3-station expansion module.

Does ESP-SM3 work on ESP-ME3?
Yes. Use it when a bay only needs three more stations, or on older ESP-M / ESP-SMT controllers that cannot take ESP-SM6.

Can I mix ESP-SM3 and ESP-SM6 in one controller?
Yes on ESP-Me, ESP-SMTe, and ESP-ME3. Install 6-station modules in the earlier bays first so station numbering stays cleaner.

Do I need to power down to install ESP-SM3?
No. It is hot-swappable. Wait about 30 seconds after seating for the new stations to become available.
