Replacing Your Batteries

1. When the LO Battery indicator is flashing, replace the batteries promptly with three fresh AAA alkaline batteries
2. Remove comfort control from the wallplate by pulling straight out.

Battery Tips

1. Replace the batteries as soon as LO Batt flashes in the display. The LO Battery indicator
   flashes in the display one month before the batteries run down completely.

2. Always use fresh AAA alkaline batteries. Non-alkaline batteries do not last as long and can leak, causing comfort control damage.

Battery Power (Optional)
The comfort control is designed to be programmed while relaxing in your favorite chair. Install the three AAA batteries on the back of the control and you are ready to go. When you have completed

ONE REMOTE INDOOR SENSOR INSTALLED (SELECT MODELS)
If one remote indoor temperature sensor is used, the screen showing the Inside temperature reading shows the temperature at the indoor remote sensor location.

MULTIPLE REMOTE INDOOR SENSORS INSTALLED (SELECT MODELS)
If more than one remote indoor sensor is used, the screen showing the Inside
temperature reading shows the average of all the remote indoor sensors.

Reminder Timers (Select Models)
These reminders notify you when to change your furnace filter or humidifier pad. When the time you set expires, the comfort control flashes “Change” and then ”Filter” or “Change” and “Humidifier Pad” until you reset the timer.

attempts to press a key that is locked. Pressing a locked key while Screen Locked is shown flashes
Screen Locked on the screen. Pressing an unlocked key while Screen Locked is active removes the
screen lock.

— To cancel temperature override and begin following schedule, press Cancel key.
— To unlock screen, see Advanced Settings section.

Fully Locked Screen
In this mode, all keys are locked and not functional. To unlock screen, see Advanced Settings

Reading Your Inside Humidity Level (Select Models)
Select models can sense the humidity level in the home. If your model has this feature, the humidity level in the home is shown in the lower right corner of the Home Screen.
NOTE: If the comfort control has the optional outdoor temperature sensor (select models), the indoor humidity level is displayed by pressing the More key.

Controlling Your Inside Dehumidification Setting (Select Models)
Select models read the inside humidity level and set a desired humidity level to help control dehumidification in the home.
NOTE: See step 8 on page 44.

1. Press the More key until the inside humidity percent and dehumidification setpoint are shown.
2. desired humidity level (select models) for dehumidification in the summer.
3. Press Done key to save your changes and return to the Home Screen.
4. Press Cancel key to return to Home Screen without saving any changes.

Dehumidification Control (Select Models)
If your comfort control has dehumidification control and you set a dehumidification setpoint, the comfort control attempts to control to this dehumidification setpoint by turning on the air conditioner.
In extremely high humidity conditions, comfort control keeps the air conditioner running for up to 3°F below your temperature setpoint. It does this when trying to achieve your desired humidity setpoint and balance that with your temperature setpoint.

Temperature Recovery
Your comfort control comes with a feature called Adaptive Intelligent Recovery™, which eliminates
all guesswork when setting your schedule. How long does it take the furnace to warm your house in the morning before you get out of bed or how long does it take the air conditioner to cool your house in the afternoon before you return from work? No problem.The comfort control determines that for
you.

Simply set your program schedule to the time you want the house to be at your comfort temperature.
The comfort control then turns on the heating or cooling at just the right time to have your home reach your scheduled temperature at your scheduled time.

For example—you get out of bed at 6:00 AM and want the temperature to be 70°F. Set the Wake period for 6:00 AM and 70°F. The comfort control then turns on the heat before 6:00 AM to raise the temperature to 70°F by 6:00 AM.

The comfort control alerts you that the heating or cooling system is coming on before a scheduled time by showing “Recovery” on the screen.

IMPORTANT
It takes about a week for the comfort control to adjust to local weather, your schedule, the construction of your home and your heating and/or cooling system. Your comfort control
learns from experience. Each day it checks how closely it reached the recovery time and adjusts the next day’s recovery start time accordingly.

Advanced Heat Pump Features (Select Models)
If you have a heat pump heating system, your comfort control can use some special features when used with an Outdoor Temperature Sensor, such as compressor and/or backup heat lockout based on outside temperature. For example, if your backup heat does not turn on above a designated
outside temperature, your system uses an advanced heat pump feature.

Setting the Calendar
This comfort control is designed to automatically keep current time and day in memory for up to ten years, under normal use, once the calendar is set. There are two ways to set the calendar for this comfort control:

SETTING CALENDAR AFTER COMFORT CONTROL IS ALREADY FUNCTIONING
See steps 1 through 4, in the Advanced Settings section, to set year, month and day.
