New mom here with triplets and its 105 out. Old thermostat broken. Trying to instal a Honeywell TH2110D1009, its also called the Pro 2000. I have 7 wires however, the honeywell only has room for 6. old had x, r, g,o,y,e, w2. New has y, r, c, g, o/b, w. I figure y -y, r-r, g - g, w -w2. Please help if you know what to do or what colors go etc. Honeywell will not help me.

Not sure what your system is and if compatible with this thermostat but page 4 seems to have various combinations covered including 7 wires (unless I miscounted!).
No guarantees it is right for your hook-up.
