Notes:
2 - Connection of remote unit that does not have a loop pump for s
atellite
operation.
3 - 24V Accessory relay ( see SW 2 - 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 L 2 can be removed and dual power wire sets connected directly to box lugs L1, L2,
and L3, L 4.
7 - When optional electronic air-filter is installed, power for the electronic air- filter is provided by P2
24 VAC.
8 - SW3 - 4 should be in the OFF position when using the 17P501 A01 electric heat board and
should be ON when using the 17P514 A01 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.
6 - 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 2 speed units.
1 - Place switch to 208V position to operate unit at 208V.
