Circulate fan ON time setting
NOTE − If the circulate fan mode is on, a timer is set to measure all the time
that the fan is blowing, regardless if it is running to deliver heating or cooling
or just for circulation.
Circulate" is enabled on the user’s home screen or system settings page.
It keeps air circulating from 15% to 50% percent of time. The following set-
tings approximate how long the fan will run at these typical settings:
15% (9 minutes fan run time per hour)
25% (15 minutes fan run time per hour)
35% (21 minutes fan run time per hour)
45% (27 minutes fan run time per hour).
Table 1 shows the range/condition and defaults for the system settings and
