Aurora Base with PSC cont.
With optional EA Series 10kW Auxiliary Electric Heat Shown
1 - Use copper o r aluminum conductors.
2 – When Auxil iary Heat is installe d 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).
3 – Jumpers wi re s are Factory Installed, and are
Required for auxi liary heat operation.
4 – Low vol tage wiring CLASS 2.
