    Thermostat/Fan Wiring

    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.
