Irritrol RD-1200 Returned in RD-600 Case: Mounting Hole Mismatch

An RD-1200 sent for repair returned in an RD-600 outer case (model tag blacked out but readable). The dial face still shows RD-1200. Mounting holes don't align with original wall anchors after running wires through the bottom.

Case Compatibility

RD-600 and RD-1200 cases should be identical. The internal electronics differ (station count), but the plastic enclosure, mounting points, and terminal strip locations are the same across the Rain Dial series.

Likely What Happened

The repair center likely replaced the back panel/terminal board assembly (where field wires connect) with an RD-600 version. This component differs between models because the terminal strip has fewer stations on the 600. If they swapped this part, the wire entry holes and terminal positions would shift.

Resolution

1. Contact Irritrol repair department - this is their error
2. Request correct RD-1200 back panel/terminal board
3. Or ask for a complete RD-1200 case swap

Workaround (If Urgent)

Drill new mounting holes in the wall to match the returned case, or use a plywood backboard mounted to existing anchors, then mount the controller to the backboard.
