4 - When installed the Auxiliary Heat powers blower and controls.
3 - Use manufacturer’s part number 19P592-01 (jumper bar assembly)
when single source power is required.
1 - Switch blue and red wires for 208V operation.
2 - The blk/wh and gray/wh wires are removed when Aux Heat is installed
6 - Wires provided for Auxiliary Heat low voltage control. Wires are secured at blower.
7 - Field installed SPST relay required for dual fuel installation.
