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 – When Auxiliary Heat is field installed the harness will then be connected to
the auxiliary heat unit. The auxiliary heat unit will then power the blower. Refer to
EAS/EAM/EAL Auxiliary Heat kit installation instructions.
4 – Low voltage wiring CLASS 2.
5 – Brown blower power wire routed through Current Transducer two times.
6 – Field Connected: Refer to Installation Manual and Auxiliary Heat Instructions for
Current Transducer installation.
7 – Variable speed pump low voltage harness provided with Variable Speed Flow Center.
8 – Variable speed pump power wires to connect the pump to L1 and L2 on the AXB board
are provided with Variable Speed Flow Center.
9 - Wires provided for Auxiliary Heat low voltage control. Wires are secured at blower.
10 – Ground wire only on units with aluminum air coils.

1 - Use copper or aluminum conductors.
2 - Use manufacturer's part number 19P592-01 (jumper
bar assembly) when single source power is required.
3 – When Auxiliary Heat is installed the BLK/WHT

wire from CC-L1 to PB2-2 and the GRY/WHT wire
from CC-L2 to PB2-1 must be removed (located in
the heat pump control box).
4 - When installed, the Auxiliary Heat powers blower and controls.
5 – Low voltage wiring CLASS 2.
6 – Jumpers wires are Factory Installed, and are
required for auxiliary heat operation.
