Cooling and fan only
What happens, in order
- R and Y1/G or Y2/G close; control checks safeties
- Outdoor fan and compressor start at the right speed
- Circulator blower starts on the cool speed, level and timing set by the chosen ramp profile; air cleaner terminal energized
- Thermostat opens outdoor fan and compressor stop
- Blower keeps running through a cool off delay (time and airflow set by the ramp profile), then blower and air cleaner turn off
- Fan only R and G close; after a 5 s delay the blower runs at continuous fan speed (30 percent of furnace maximum airflow) with the air cleaner on; it stops when G opens
