Operation
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 - For additional Auxiliary Heat staging place jumpers as shown.
6 - Refer to FAN SPEED table for factory settings.
7 - Wires provided for Auxiliary Heat low voltage control. Wires are
secured at blower.
