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.
9 – Variable speed pump low voltage harness provided with Variable Speed Flow Center.
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.
11 - Field installed SPST relay required for dual fuel installation.
12 - Refer to units 5 SPEED ECM MOTOR LOW VOLTAGE CONNECTION table for
factory settings.
13 – Ground wire only on units with aluminum air coils.
