With optional EA Series 10kW Auxiliary Electric Heat shown
Place auxiliary heat schematic from kit here
5 – Low voltage wiring CLASS 2.
3 – Jumpers wires are Factory Installed, and are
Required for auxiliary heat operation.
1 - Use copper or aluminum conductors.
2 – 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.
10 – Variable speed pump power wires to connect the pump to L1 and L2 on the AXB board
are provided with Variable Speed Flow Center.
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
12 - Refer to units 5 SPEED ECM MOTOR LOW VOLTAGE CONNECTION table for
factory settings.
5 - Y2 input wire Tan not connected on Single Speed units. Wire is secured at blower.
6 - Wires provided for Auxiliary Heat low voltage control. Wires are secured at blower.
7 – Brown blower power wire routed through Current Transducer two times.
8 – Field Connected: Refer to Installation Manual and Auxiliary Heat Instructions for
Current Transducer installation.
3 – When Auxiliary Heat is field installed the harness will 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. Wires are secured at blower
9 – Variable speed pump low voltage harness provided with Variable Speed Flow Center.
11 - Field installed SPST relay required for dual fuel installation.
4 – Low voltage wiring CLASS 2.
13 – Ground wire only on units with aluminum air coils.
