Jen, I am a expert here, Your question has been reported, This can be quite difficult when you start having this many wires, What kind of thermostat did you remove?
Im looking now. Did you remove all the wires?
Im looking at old thermostat manual now, I see no F slot, i am not familiar with the Hai rc100 t-stat Im going to opt out and let another professional help, I know from experience where most of the wires go but regarding the few I don't it can cause issues if there placed wrong and Im not wanting to take that chance
My name is Billy.
Very simply, on the older thermostats F meant FAN...which is what the G terminal/green wire does.. So Old F = New G.
What other wires do you need help with?
out of all those wires..how many were actually hooked up?
Most of the time there are extra wires in the cables.
I understand now.
You have dual stage cooling and multistage heat. The thermostat you have (rth7500) will not accommodate all the features you have on your system.
So we have 2 choices....dumb the system down by combining features or get a new thermostat capable of multiple stages.
Example...you have 2 stages cooling...we would have to dumb the unit down and put 2 wires from 2 stages together to make one stage....I do not recommend doing this but it is an option.
You will need a thermostat that says 2h/2c...and one with emergency heat capability.
So basically your system has more features than the 7500 can provide for.
You are very welcome and you are making the right choice.
If you have questions when you get the new thermostat let me know.
Make sure new thermostat is :
Heat pump compatible
Has emergency heat option
2 stage heat and 2 stage cool at a minimum.
If you see 3 and 4 stage that is fine...we just do not use the extra staging. Just rate service to close
