Wiring Diagrams used with the ADP-1103-TPX:
- #12B1. Same as #12B But Uses Adaptor (ADP-1103-TPX) so that Damper Will Open During Furnace Firing.
- #12B2. Same as #12B1 But Uses a Power Close Replacement Air Damper (HAC-0x10-SPC) That Also Opens During Furnace Firing.
- #12B4. Same as #12B3 But Uses Adaptor (ADP-1103-TPX) with the Adaptor (ADP-1102-TPX) so Damper Also Opens During Furnace Firing.
