Compatibility of ESP‑ME and ESP‑SM6 Modules with Discontinued ICC Controller

After a lightning strike damaged an ICC controller, the owner asks whether Rain Bird ESP‑ME and ESP‑SM6 modules can replace the burnt ICC module, and whether a $600 repair quote is reasonable.

Answer

Hunter (ICC) and Rain Bird modules are not interchangeable. The ICC series is discontinued, so you cannot mix brands. If a replacement ICC module isn’t available, the entire controller must be replaced.

A $600 installed price for a new controller is within typical market range. The number of zones will determine the exact model needed.

If you locate a spare ICC module, that could be a cheaper fix, but availability is limited.
