NOTES
97P774-02 6/29/06
1. Switch Blue and Red wires for208V operation.
2. Connection of remote unitthat does not havea loop pump for slave operation.
3. 24V Accessory relay (see SW2 -3 for description of operation).
4. The blk/wh and gray/wh wires are removed when Aux Heat is installed.
5. Buss lugsL1 and L2can be removed and dualpower wire sets connected directly to box lugs L1, L2,and L3, L4.
6. DHW pump only in modelswith hot water generation option.
7. Air Flow Configuration Example: SW1 configured for dip 1 as low, dip 3 as medium, and dip 5 as high speed ECM2 fan.
8. SW3-4 should be in theOFF positionwhen using ECM motor and 17P501A01 electric heat board and should be ON when
usingECM2with17P514A01 electricheatboard.
9. SW2-8 must be in the OFF position for pulsed “L” lockout signal andinthe ON position for constant “L” lockout signal.
10. Whenoptionalelectronicair-filterisinstalled,powerfortheelectronicair-filteris providedby P2-2and24VAC.
11. Comfort Alert fault output to Premier Control Board.
12. This switch allows the unit to down stage with the t-stat when off and finish with second stage when on. Finish on second
stage reduces stage changing in recip dual capacity compressors and should be ON for unzoned Dual Cap E Series or
Premier 2 Speed.
