Description
(In alphabetical
order)
When enabled, smooth set back begins recovery up to two hours before the programmed time so that the programmed temperature is reached at the corresponding
programmed event time. Assume 12°F (6.6°C) per hour for first-stage gas/electric heating and 6°F (3.3°C) per hour for first-stage compressor based heating or cooling.
With Smooth Set Back disabled, the system will start a recovery at the programmed time. Options are enabled or disabled. Default is enabled.
The SSR set point calculation is as follows:

Recovery (SSR)
Rules for SSR:
• SSR is enabled when both "Smooth Setback Recovery" is set to enabled (default) and the program schedule is turned on.
• SSR does NOT turn off stage delay timers.
• SSR will NOT change the dead band between heating and cooling modes.
• SSR will not overshoot the target set point.
• SSR will reset if the user updates the program schedule during the active SSR period
Enabled (default) setting: When enabled all stage delay timers (stages 2 through 6) are enabled and will serve to bring on additional stage(s) of cooling or heating on a
Stage Delay
timed basis (default 20 minutes)
Timers
Disabled setting: All stages delay timers are disabled. Heat/cool stages are changed based on temperature
(First)
The second-stage delay timer (when stage timers is Enabled) is used for both HEATING and COOLING.
Stage Delay
Second through Sixth Stage Delay timer (where applicable) - If staged delay timers are "Enabled", the default is 20 minutes but can be programmed from 5 to 120
Timers
minutes in 5-minute increments. If the first stage fails to advance the ambient temperature toward the set point by 1.0°F (0.56°C) in the programmed delay time, then
the second stage is activated.
(2 through 6)
Stage Differentials
Number of stages in thermostat is dependent on equipment that is installed.
(1 through 6)
Range is -5.0 to 5.0°F (-2.78 to -2.78°C). Default is 0.0°F (-0.0°C).
Temp Reading
If it is determine that the actual temperature being detected at the thermostat is off based on independent readings using other ambient temperature reading devices,
Calibration
the display can be adjusted using this setting.
Options are Normal and Comfort. Default is Normal. The Feels-Like feature factors in the outdoor temperature and indoor humidity for a more accurate control of the
temperature in the home. Either an outdoor temperature sensor is used or Internet Weather is enabled for this feature to operate. Modifying this setting here will also
change the feature status on the user settings screen.
Temperature
Control Mode Normal - This setting cools or heats the home to the desired temperature setting (feels-like) is OFF.
Comfort - This setting cools or heats the home to the desired temperature setting (Feels Like) is ON. When set to ON, other parameters are modified to optimal settings
for this feature. Those setting changes will be listed on-screen when Comfort is enabled.
