EPR it is simple, it controlls the evaperator temps and by turning it one way or the other it can help to adjust a temp on a certain evap in a rack system. We are not building a clock just a/c it is more simple than what the books will tell you. A CPR is another valve used sometimes as well to adjust the amps of a compressor and its load at the same time.
