Notes:
1 – Switch Blue and Red wires for208V operation.
2 - Connection of remote unit that does not have a loop pumpfor slave operation.
3 - 24V Accessoryrelay (see SW2 - 3 for description ofoperation )
4 - The blk/wh andgray/wh wires are removed when Aux Heat is installed .
6 - DHWpump onlyin models with hot water generation option.
5 - Buss lugs L1and L2 can be removed and dual power wire sets connected directly to box lugsL1, L2 ,
and L3, L4.
10 - When optional electronicair -filter is installed,power for the electronic air-filterispr ovided by P2-2 and
24 VAC.
8 – SW3-4 should be in the OF F position when usingthe17P501A01 electric heat board and
should be ON when using the17P514A01 electri c heat board .
11- Comfort Alert fault output to Premier Control Board
9 – SW2- 8 must be in the OFFposition for pulsed “L” lockout signal and in the ON position for constant
“L” lockout signal .
7 – This Switch allows the unit todown stage with thet-stat when OFF and finish on secondstage when
ON.Fini sh second stage reduc es stage changing in recip dual capacity compressor s and should
be ON for unzoned Dual Cap E -Series or Premier2 speed units.
