TrueEase HE250 to Prestige EIM Wiring

I'm Updating my thermostat to a Prestige 2.0 with EIM and adding a Honeywell TrueEase HE250 Bypass humidifier.

I have installed Thermostat (2 wire)and EIM and Heat and AC both work. I have wired the Humidifier to the transformer that came with it. The transformer is attached to a conduit box and has constant power. the wires from transformer to Humidifier have 24v. According to the wiring instructions that came with Humidifier and Prestige the only other wires i needed to hook up are the HUM on the Humidifier to U1 on EIM. I have done this and when I power on the humidifier it runs through what i would call a function check. (Baffle turns 180 degrees and the lights light up. But when the thermostat calls for humidity nothing happens at the humidifier. DIP switches on Humidifier are both ON (top one left, Bottom Right

Yellow and Red go to transformer. Blue and Green go to EIM terminals U1

Nevermind!

I flipped the dip switches on the humidifier opposite of what the directions said (as stated above) and everything works perfect..
