If your thermostat has batteries, a low battery warning flashes on the home screen for approximately 30 days. NOTE: If the batteries are not replaced when the Low Battery warning is flashing, the LO batt screen will display continuously and the thermostat will not operate until the batteries are replaced. M19963 NOTE: Although the thermostat has a low battery indicator, replace the batteries once each year to prevent leakage and to prevent the thermostat and heating/cooling system from shutting down due to lack of battery power in the thermostat. 19 69-1701 1. Remove thermostat from the base by pulling straight out. WALL REMOVE DURING INSTALLATION M19919 2. Install three new AAA alkaline batteries so all positive ends alternate up, down, up. NOTE: Always use AAA alkaline batteries. 20 69-1701 BATTERIES (3) M19918 3. 4. Place the thermostat back on its base by aligning the terminal screw blocks with the pins on the back of the thermostat. Push the thermostat straight onto the base. NOTE: All Program Schedule, Date and Time information is retained while the batteries are being replaced. 21 69-1701 Cleaning Your Thermostat Screen The thermostat has a touch screen interaction.

(This is the Advanced setting you set or the reload value you selected in step 2.) Press Done or Cancel key to return to the Home Screen. Screen Locked You can fully or partially lock out the keys on the touch screen interface. See Advanced Settings for information on turning these features on or off. If the thermostat shows "Screen Locked," your thermostat screen is either fully or partially locked. 26 69-1701 TUE FAN AUTO SCREEN LOCKED Inside Set To SYSTEM HEAT PM Following Schedule SCHED HOLD CLOCK SCREEN MORE M19965 Partially Locked Screen When partially locked, the screen indicates Screen Locked for 5 to 7 seconds whenever the user 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. In this mode, all keys are locked except the Temperature Up and Down arrow keys: -- User can change temperature up or down but cannot change schedule settings. -- Temporary temperature change lasts until next scheduled period and that time shows on screen. -- To cancel temperature override and begin following schedule, press Cancel key. -- To unlock screen, see Advanced Settings section. 27 69-1701 Fully Locked Screen In this mode, all keys are locked and not functional. To unlock screen, see Advanced Settings section. The screen continuously displays "Screen Locked." 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 thermostat has the optional outdoor temperature sensor (select models), the indoor humidity level is displayed by pressing the More key. TUE FAN AUTO Inside Set To SYSTEM HEAT PM Following Schedule Humidity SCHED HOLD CLOCK SCREEN MORE M19966 28 69-1701 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: 1. Press the More key until the inside humidity percent and dehumidification setpoint are shown. Inside Humidity DEHUMIDIFIER DONE CANCEL M19967 2. 3. 4. Use Up and Down arrow keys, located to the right of the dehumidifier setpoint, to set your desired humidity level (select models) for dehumidification in the summer. Press Done key to save your changes and return to the Home Screen. Press Cancel key to return to Home Screen without saving any changes. 29 69-1701 Dehumidification Control (Select Models) If your thermostat has dehumidification control and you set a dehumidification setpoint, the thermostat attempts to control to this dehumidification setpoint by turning on the air conditioner. In extremely high humidity conditions, thermostat 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 thermostat comes with a feature called Adaptive Intelligent RecoveryTM, 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 thermostat determines that for you. Simply set your program schedule to the time you want the house to be at your comfort temperature. The thermostat 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 thermostat then turns on the heat before 6:00 AM to raise the temperature to 70°F by 6:00 AM. The thermostat alerts you that the heating or cooling system is coming on before a scheduled time by showing "Recovery" on the screen. 30 69-1701 TUE FAN AUTO Inside Set To SYSTEM HEAT PM Following Schedule Recovery Humidity SCHED HOLD CLOCK SCREEN MORE M19968 IMPORTANT It takes about a week for the thermostat to adjust to local weather, your schedule, the construction of your home and your heating and/or cooling system. Your thermostat learns from experience. Each day it checks how closely it reached the recovery time and adjusts the next day's recovery start time accordingly. 31 69-1701 Advanced Heat Pump Features (Select Models) If you have a heat pump heating system, your thermostat 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 Calendar This thermostat 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 thermostat: SETTING CALENDAR AFTER THERMOSTAT IS ALREADY FUNCTIONING See steps 1 through 4, in the Advanced Settings section, to set year, month and day. SETTING CALENDAR WHEN THERMOSTAT IS FIRST POWERED When this thermostat is first powered, the display is ready to set the calendar. 32 69-1701 SET CURRENT DAY SET MONTH MON TUE WED D THU FRI RI SAT AT SUN DONE USE ARROWS TO SET YEAR AND TIME MON W WED THU FRI SAT AT SUN OK TO PICK MULTIPLE DAYS SCREEN LOCKED U CHANGE FILTER UV LAMP HUMIDIFIER PAD R DONE M19921 33 69-1701 Advanced Settings Your thermostat has many advanced settings to match your heating and cooling system.
