5 - Air Flow Configuration Example: SW1 configured for dip 3 as low, dip 5
as medium, anddip 7 as highspeed ECM2 fan.
6 - SW3-4 should be in the ON position when using Electric Heat control
17P514A01, and it should be in the OFF position when using Electric
Heat control 17P501A01.
7 - When using thermostat TA32E12, SW2 -8 should be in the ON position.
When using 24VACthermostats, SW2-8 should be in the OFF position.
