When multiple items are flashing, changes affect only one of the items. The thermostat can control up to four different schedule periods per day: Occupied1--Work arrival time. Period to keep space at a comfortable temperature. Unocc1--Work exit time. Period to keep space at an energy-saving temperature. Occupied2--Second occupied period. Unocc2--Second unoccupied period. NOTES: -- -- Available schedule times are at 15-minute intervals. With default settings, all four periods can be programmed. This can be changed to allow only Occupied1 and Unocc1 programs. To use only Occupied1 and Unocc1, see Step 8 in the Advanced Settings section. 5 63-2626--1 Editing Schedule 1. 2. 3. 4. 5. Press MORE. Press SCHEDULE. Press EDIT.

HEAT -- thermostat controls the heating system. OFF -- both heating and cooling systems are off. COOL -- thermostat controls the cooling system. AUTO -- thermostat controls both the heating and cooling systems based on temperature. 9 63-2626--1 SETTING FAN Fan selections vary based on the HVAC system type. ON--fan runs continuously. Use this setting for improved air circulation or for more efficient central air cleaning. AUTO--fan is controlled by the system. Typically, the fan runs only during cooling or heating operation. Setting Temperature Overrides There are three temperature override options: -- Hold Temperature Until -- Override, and -- Holiday. HOLD TEMPERATURE UNTIL Holds the temperature temporarily until the time set by the user, or the next scheduled period time: 1. Press an arrow key or the Override key. TEMPORARY SET TO appears on the screen. The time defaults to the next scheduled period start time. 2. Use the Up and Down keys to change the desired temperature. NOTE: If HEAT or COOL begins to flash, your temporary setting is at, or beyond, the deadband. The thermostat operates based on the override setting throughout the hold time. 3. Press NEXT. 10 63-2626--1 NOTE: The ability to change settings remains for approximately seven seconds. Once neither the temperature nor the time continue to flash, you must restart at step 1 to make changes. 4. Use the Up and Down keys to set the desired time for the thermostat to resume the programmed schedule. Tue NOTE: The installer setup can limit the length of time for an override to 1, 2, 3, or 4 hours beyond the current time. 5. Press CANCEL to cancel "Hold Temperature Until" and resume the schedule.

The only thing that allows the fan to turn off during occupied periods is a manual fan override from On to Auto. If the mode is Unoccupied, fan control is the same as with the Auto setting. This is true even when the display indicates "On". If the thermostat is not controlling the fan, the fan blade symbol might not appear even while the fan is running. 13 63-2626--1 Replacing Batteries With proper power and connections, the thermostat does not require batteries. Thermostats with batteries provide a warning when the batteries run low. This warning flashes on the main screen for approximately 30 days. NOTES: -- If batteries are not replaced when Low Battery warning is flashing, the LO batt screen displays continuously and M22383 thermostat stops operating until batteries are replaced. Despite the low battery indicator, it is recommended that you replace the batteries once each year. Do this to prevent leakage and to prevent the thermostat and HVAC system from shutting down due to lack of thermostat battery power. -- 14 63-2626--1 Replace the batteries as follows: 1. Remove the thermostat from the base by pulling it straight out. 2. Install two new AA alkaline batteries with proper polarization. NOTES: -- -- Always use AA alkaline batteries. All programming (Schedule, Date and Time) information is retained during battery replacement. WALL M22384 15 63-2626--1 3. Place the thermostat back on its base: a. Align the terminal screw blocks with the pins on the back of the thermostat. b. Push the thermostat straight onto the base. After two minutes, the device automatically returns to the main screen. To return to the main screen before the two minutes pass, press a key.
