Wiring Schematics cont.
Aurora BASE with 5-Speed ECM cont.
With optional EA Series 10kW Auxiliary Electric Heat Shown
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).
1 - Use copper or aluminum conductors.
3 – Jumpers wires are Factory Installed, and are
Required for auxiliary heat operation.
4 – Low voltage wiring CLASS 2.
