Envision Series - Dual Capacity Split Wiring Schematic - 208-230/60/1

	Notes:
S	1 - 24V Accessory relay (see SW2 - 3 for description of operation )
	2 – This Switch allows the unit to down stage with the t -stat when OFF and finish on second stage when
C
	ON. Finish second stage reduces stage changing in recip dual capacity compressors and should
	be ON for unzoned Dual Cap E -Series or Premier 2 speed units.
R	3 - Comfort Alert fault output to Premier Control Board
	4 – SW2-8 must be in the OFF position for pulsed “L” lockout signal and in the ON position for constant
	“L” lockout signal.

Ext Pump			Blue	Red		Black	5 - DHW pump only in models with hot water generation option .
