5 - Air Flow Configuration Example: SW1 configured for dip 3 as low, dip 5 as
medium, and dip 7 as high speed ECM2 fan.
7- Whenusingthermostat TA32E12,SW2-8shouldbeintheONposition.
When using 24VAC thermostats, SW2-8 should be in the OFF position.
8 - When optional electronic air-filter is installed, power for the electronic air-filter
is provided by P2-2 and 24 VAC.

1 - Place switch to 208V position to operate unit at 208V.
CS - Current Switch
6 - 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 - SW3-2 shouldbe OFF to operate with zonecontrol systemand ON to operate
with un-zoned system.
