Programming Fan Operation; Comfort Recovery Operation - York LX series Owner's Manual

Installer Setup
Programming the Fan (Setup Steps 35 - 38)
(This feature not available on all models)
Fan Program (Setup Step 35) - This feature allows the fan to be programmed to turn
on automatically for a specified period during the day. If this feature is set to ON, the
next three steps will appear.
Minutes Of Fan Runtime Per Hour (Setup Step 36) - This setting specifies the num-
ber of minutes (0 - 60, in increments of 5) that the fan will run at the top of each hour.
Fan Program Start Time (Setup Step 37) - This setting specifies the hour of each day
when the programmable fan feature will start.
Fan Program Stop Time (Setup Step 38) - This setting specifies the hour of each day
when the programmable fan feature will stop. NOTE: Setting the Stop Hour equal to
the Start Hour will cause the fan to run 24 hours a day.
Fan Off Delay in Seconds (Setup Step 55)
(This feature not available on all models)
This feature allows the user to increase the cooling or electric strip heating efficiency
of the system. The thermostat may be programmed to continue running the fan after a
call for cooling or electric strip heating 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 or
electric strip heating has been satisfied.
Comfort Recovery (setup step 69)
(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.
