Hydro Rain HR6100 Shows Gibberish Codes – Controller Failed

After power outage, display alternates IR.CA/SC.CA. Codes meaningless on this vintage unit.

Fix

  1. Remove battery; unplug 1 min.
  2. Repower (no battery); reprogram.
  3. If gibberish persists → replace controller.

Irritrol Rain Dial is modern equivalent.
