Help!!

I would like to turn the fan on on my tempstar vs 95 gas furnace. I can not do it through my thermostat - no wiring for it. Is there a way to turn in on right on the furnace (some secret switch?)? I need just the fan on, not the heat.


If you know what to do, please help!!!

You can jump G to R.

How many conductors do you have?

The Honeywell IAQ can control heating, cooling and fan with 3 wires.





The Carrier Edge can do this with 2 wires.

Wire a light switch beside the furnace, connected to R and G.

The vision pro iaq is an overkill for a heat only system; there are cheaper ways to get fan control to the stat.

To utilize that furnace to it's potential, it should be connected to a 2-stage t-stat which requires 4 wires on a heat only system (power, fan, first stage heat, second stage heat).

If pulling a wire isn't an option and you want a two stage stat with fan control, a wireless model is a good option. (Canada - Model)

There's also FAST-STAT - Wiring Extenders and Thermostats Controls
