Job Checkin

Master bedroom unit Converted communicating system into a 24 volts system. I found a couple of Goodman control board plugs in my bag to convert the unit over. We wired in R,C,Y1,Y2, and W. We had 3 wires to the condenser and a transformer already installed. I used the transformer to power the board and the 3 wires to operate Y1, Y2, & C. At the thermostat we robbed the fan wire for Y2.
