Narrative:
On vector approach to 8R iah outside of eelpo at 5000 [ft] control cleared us for ILS to maintain 3000 [ft] until established. I did not realize first officer had reset altitude window to 2000 [ft]. Descended to 2000 [ft] outside eelpo on autopilot. We failed to [verbalize] new altitude.
