I never knew new furances wouldn't come with a "summer fan"...pretty dumb!

I don't need A/C here but want to circulate the cool air around by running the fan only.

Here is the 2 ways i have found so far on the net
1) Run jumper from R to G in the furnace and run it to a switch, then somehow wire this to the G on your thermostat

2) use 18/5 wire and get a Honeywell Vision Pro 8000 that has a "Circ" option


Now I don't think it can be that hard, just need to know where I can find some info so i can wire it to my thermostat. I talked to my furnace installer who said it doesn't come with a summer fan and that an electrician can wire in a new thermostat if you want...I asked would an electrician know how to wire it and they said "he should..."

Nice!

Just run a 18/3 or better(if you want to use a thermostat that isn't battery powered) wire to your current thermostat location, and use any thermostat that has A/C control also. Then just turn the fan switch to "on". Need to have RH/RC jumpered in the stat, and connect stat W to W in furnace and stat G to G in furnace. Along with C to C if you use a stat that is not battery powered.

Thanks for replying, wold you be able to walk a total rookie through this?

Right now I have a thermostat that is battery operated, so are you saying to jumper RH/RC in the stat, then jumper W to W and G to G in the furnace?

what wire connects the stat to the furnace jumpers?

If you could walk me through it, I know it can be frustrating, but I don't want to do it wrong and then fry the board on the furnace...

wire G in furnace to G in stat and jumper RC to RH in stat if not already jumpered. The fan control will now function from the stat.
