A B737-200 was dispatched in non compliance with the engine fuel heat valve instead of the anti-ice valve wired open per the MEL. Aircraft returned to the field due to high oil temperature.

Narrative:
Inbound flight crew reported #2 engine right anti-ice valve stuck in in-transit position. The decision was made to defer the valve in the open position due to WX conditions. I inadvertently performed the MEL special procedure on the fuel heat valve, which is located in close proximity to the anti-ice valve. The aircraft departed, experienced higher than normal oil temperature and returned to ZZZ. When the crew reported the discrepancy from the air, I realized the mistake I had made and corrected the fault when it returned to the gate.
