Notes
3 - Use manufacturer’s part number 19P592-01 (jumper bar assembly)
when single source power is required.
1 - Switch blue and red wires for 220V operation.
2 - The blk/wh and gray/wh wires are removed when Aux Heat is installed
4 – Variable speed pump low voltage harness provided with Variable Speed Flow Center.
5 - For additional Auxiliary Heat staging place jumpers as shown.
6 - Wires provided for Auxiliary Heat low voltage control. Wires are secured at blower.
7 – 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.
8 – Brown blower power wire routed through Current Transducer two times.
9 – Field Connected: Refer to Installation Manual and Auxiliary Heat Instructions for
Current Transducer installation.
10 – Communication cable routed through Ferrite Toroid four times.
11 – Compressor power cable routed through Ferrite Toroid three times.
12 – Variable speed pump power wires to connect the pump to L1 and L2 on the AXB board
are provided with Variable Speed Flow Center.
