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 - Wires provided for Auxiliary Heat low voltage control. Wires are secured at blower.
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.
