Programming Fan Operation; Comfort Recovery Operation - Source 1 S1-TBSU22HN Owner's Manual And Installation Instructions

Installer Setup
Fan Mode (Setup Step 5)
This feature allows the following options:
Fan Auto - If Fan Auto is selected, the fan will run while there is a call for heating or
cooling.
Fan On - If Fan On is selected, the fan will run continuously during Occupied Mode
and turn off during Unoccupied Mode.
Minutes of Fan Purge (Setup Step 37)
(This feature not available on all models)
When this feature is activated, the fan will turn on during an unoccupied period at a
preset amount of time prior to Occupied 1. This preoccupancy fan purge timer may
be set from zero to three hours, in 15 minute increments. Zero means this feature is
turned off.
Fan Off Delay in Seconds (Setup Step 51)
(This feature not available on all models)
This feature allows the user to increase the cooling efficiency of the system. The ther-
mostat may be programmed to continue running the fan after a call for cooling has been
satisfied. This delay can be set for 0, 30, 60, 90, or 120 seconds. If set to 0, the fan
will not run after a call for cooling has been satisfied.
Comfort Recovery (Setup step 65)
(This feature not available on all models)
With Comfort Recovery on, the thermostat will attempt to reach the Morning
setpoint temperature at the exact time programmed into the thermostat. Comfort
Recovery, only works when the thermostat enters the Morning mode from the
Night mode. For example, if the Night program is set for 11pm at 65°F heating
and 85°F cooling, and the Morning program is set for 6am at 72°F heating and
75°F cooling, the thermostat will turn the system on before 6am in an effort to
bring the temperature to its correct setting at exactly 6am. The thermostat
learns from experience, so please allow 4-8 days after a program change or
after initial installation to give Comfort Recovery time to adjust. If used with a
heat pump, electric strip heat will be disabled while Comfort Recovery is active.
