Hi gang - looking for some help here. I wired a brand new heater and the control board doesn't light up, nothing - no signs of life at all. I double checked my connections and everything is as it should be - not sure why it is not coming on... there are 4 wires (red, black, white, green) very small that are supposed to go to the control system - but they do not seem to make any difference on or off... anyone know a trick or tip that I am missing here> Thanks!
