From the test report, a US FCC radiation emission test from the appearance, probably to get a UL and possibly CSA approval. The remote operates at 433 MHz give or take. 120 VAC primary with that going out in 2 of the 5 wires. A third wire seems to be rectified AC going out (+ out or - out?) also something across the rectified +/- but hard to determine what. A 4th wire has a pretty heavy PC trace so must be a fairly high current.
