Notes:
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 .
6 - DHW pump only in models with hot water generation option .
5 - Buss lugs L1 and L2 can be removed and dual power wire sets co
nnected directly to box lugs L 1, L2 ,
and L3, L4.
10 - When optional electronic air-filter is installed, power for the electronic air-filter is provided by P 2-2 and
24 VAC.
8 – SW3-4 should be in the OFF position when using the 17P501A01 electric heat board and
should be ON when using the 17P514A01 electr ic heat board .
11- Comfort Alert fault output to Premier Control 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.
7 – This Switch allows the unit to down stage with the t -stat when OFF and finish on second stage when
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.
