Notes:
2 - 24V Accessory relay (see SW 2 -3 for description of operation)
5 - Air Flow Configuration Example: SW1 configured for dip 1 as low, dip 3 as medium, and dip 5 as high
Speed ECM2 fan
4 - When optional electronic air - filter is installed, power for the electronic air -filter is provided by P2- 2 and
24 VAC.
6 - SW3-4 should be in the OFF position when using the 17P501A01 electric heat board and
should be ON when using the 17P514A01 electric heat board .
3 - Dual capacity units only.
7 - SW2-8 must be in the OFF position for pulsed “L” lockout signal and in the ON position for constant
“L” lockout signal.
8 - 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 - 460 volt units use a 265 volt singe phase ECM motor which requires a dedicated neutral from the
service panal.
