Question about Hunter Fan Company 5/1/1 Programmable Thermostat
I have an old 1970 ITT general control Model number T90H110A137 with the letters left to right
G F C H V and the letters on the new Hunter don't match up. I know I don't use the C wire and F & G control the fan. My furnace is a gas furnace with AC.

Here is a link that will have wiring diagram it is for a similar model hunter. Also check your dip switch on the back of the stat to ensure it is set for gas (HG) or electric heat (HE) depending on your type of unit. Good Luck. Rule of thumb for most four wire systems is RED (power to stat) Yellow (Cooling) Green (Fan) White (heat)

SOURCE: hunter fan/light control wiring
solution depends on how many wires are in the ceiling box. was there a ceiling fan in place before? were the light and fan controlled by seperate switches or was there only one switch? if two switches, then there should be two seperate hot wires in the ceiling box. if only one switch, then only one hot wire in box. if only one, then your black and red from the fan will wire together to the single hot. green goes to the bare copper wire, if not one, then not needed

There is no real color code for wiring but the standard is red wire to r, yellow wire to y,white wire to w, green wire to g, blue wire to c. since there's no c on your t- stat its probably battery operated, but in your case im betting white wire to w, and blue wire to g.

By describing the wires from your new thermostat and your old one, it sounds like your new thermostat is not compatible with your system. If you have seven wires now, then you more than likely have a heat pump system and you have to get a thermostat that is compatible with this type of system. Then you will have the connections you need.
