Need Help Installing New Thermostat !!!

Take the Hunter back to Home Depot. It will break in a year or two. The T-stat should have came with instructions and you should have written down what every wire went to. All t-stats are similar in wiring. R, C, Y1, Y2, G, W1, W2, O/B. The X on your old t-stat is a common terminal for the monitor lights. Your missing a wire for O or B from your old t-stat. O energizes the reversing valve for cooling. B energizes reversing valve for heat.
