Narrative:
Student training flight. During the descent to the airport (rmn) we noted that the winds were a direct crosswind; with an aircraft on the RNAV (GPS) to [runway] 33. We elected to continue to [runway] 33. A piper twin comanche made a call saying they intended to use runway 15. We had a brief radio conversation about active runway; and the comanche elected to switch to [runway] 33.during initial approach to the airport; whist on the downwind leg; student was configuring the aircraft as we approached 180 abeam (perch). I was the flight instructor; pilot not flying; and saw a diamond; which I assume was the diamond on the RNAV; at our altitude about to hit our aircraft. I grabbed the flight controls and initiated a descent (since the other aircraft was climbing) from 1;200 feet MSL to 900 feet MSL. We were never in any danger of hitting objects on the ground during this evasive action. I continued to fly the aircraft to a touch and go landing before we continued our training mission.the diamond had announced that he intended to break off the approach. He may have been confused about the twin comanche using [runway] 15; but given that we had a radio conversation on CTAF; and we made our mid-field downwind on [runway] 33 call; there should have been no confusion. The diamond did not execute the proper missed approach/break off procedure.
