Thermostat/Fan Wiring

[dexter18]

I recently had a Trane XV 95 installed. It is currently connected to the Thermostat to deliver heat only (with fan set to "on" or "auto"). I do not have central air, or a dehumidifier. However, I would like to have the fan run continuously so I can have my air filtered. I know I need another set of wires running from my Stat to the Furnace Contacts. I do not know which ones to connect and or bridge if necessary ?! Please Help.

The current wiring configuration is as such,

Thermostat:
In the order of wire color to contact.
BK- R
W-W

Furnace:

BK-R
W-W1 bridge to W2

Call a pro and save yourself from burning up the transformer. it wont cost much to wire a stat. cost more to come in after the fact.

well tell whomever just installed your equipment ' you want the fan "on" option' and they will connect the proper wires and/or pull a new set. luck dan

Yes, fan ON should be an option you don't need to ASK for.
