I am installing a new Honeywell thermostat with our variable speed american standard furnace. I am missing the c wire as it only has 4 wires now. I ordered and will pull a new 8 wire cable as access is pretty easy. My question is how far should I go....
If I pull the new wire and connect how it is....it appears the white wire is ran to w2 AND w1 on the furnace. I believe this means it is set to timer mode and runs on low for 10 minutes then switches to high heat mode.
I can run it how it is, add the c wire and leave the new thermostat in the default settings it comes as correct?
OR
Should I run a separate wire for w1 and w2? This would change the thermostat to call for stage 2 I believe. I am not sure what is all involved if I did that. I am thinking change the thermostat to reflect 2 stage? I am thinking I also have to change something on the furnace......Is all of that worth it or just run it like it is adding the C wire?
