Notes
1 - Switch blue and red wires for 208V operation.
2 - The blk/wh and gray/wh wires are removed when Aux Heat is installed
3 - Use manufacturer's part number 19P592-01 (jumper bar assembly) when single source power is
required.
4 - When connected the Auxiliary Heat powers blower and controls. Wires are secured at blower.
5 – Low voltage wiring CLASS 2.
6 - Refer to FAN SPEED table for factory settings.
7 - Wires provided for Auxiliary Heat low voltage control. Wires are secured at blower.
8 - Field installed SPST relay required for dual fuel installation.
9 – Ground wire only on units with aluminum air coils.
