1. Switch Blue and Red wires for 208V operation.
2. Connection of remote unit that does not have a 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 lugs L1 and L2 can be removed and dual power wire sets connected directly to box lugs L1, L2, and L3, L4.
6. DHW pump only in models with 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 the OFF position when using ECM motor and 17P501A01 electric heat board and should be ON when
using ECM2 with 17P514A01 electric heat board.
9. SW2-8 must be in the OFF position for pulsed “L” lockout signal and in the ON position for constant “L” lockout signal.
10. When optional electronic air-filter is installed, power for the electronic air-filter is provided by P2-2 and 24 VAC.
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.
