    TRANE XR13 schematic
    I have a TRANE XR13 2TWR3024 heat pump. The schematic drawing, that came with the unit, shows a circuit board labeled DFC. There are no details on the drawing except the contacts of three relays, K1, K2 and K3. Can someone tell me how these three relays are controlled or if a complete schematic is available?

    Thanks, John

    No complete schematic available to the public. For safety reasons the board is to be replaced not repaired.
