OK I'm trying to install a hunter model 44155c in my home.the problem is that the wires coming from the wall are 7 strong and the new thermostat has on 6 spots for wires and the colors or lettering are not the same.so how do I determine which wire goes where without burning my house down and not shorting out the new thermostat.the instruction sheet shows a guild for 2-3-4-5 wire or single stage installation but no 7 wire... help please
