Page 16: Hardware Setup Options
HARDWARE SETUP OPTIONS: On the thermostat’s circuit board, there is a row of DIP switches, labeled #1 through #9. The position of these switches will change how the thermostat operates, and also how information is conveyed to you on the LCD display screen. - Page 17 SWITCH #3 (PERIODS): [OFF/DOWN = 4, default] The thermostat uses four temperature program periods in both heating and cooling (MORN, DAY, EVE, and NITE). Each period has a separate start time and a set temperature. [ON/UP = 2] The thermostat operates in the same manner as above, however there are only two temperature program periods for heating and cooling (DAY and NITE).

SWITCH #8 (BATTERY MONITOR): [OFF/DOWN = ON, default] This setting, regularly monitors the battery level, and shows “LOW BAT” on the screen if the batteries need to be replaced. Use this setting at all times when batteries are present in the thermostat. [ON/UP = OFF] This setting only applies if you are NOT physically using batteries in the thermostat, and are powering the thermostat entirely from the system (“C”... - Page 19 NOTE: The Fan Mode switch only works if your system provides a wire for the thermostat’s “G” wire terminal, to control a blower fan. The Fan Mode switch has no effect in systems that do not have a blower fan (such as a hot water radiator system).

Page 20: Set Day And Time
OPERATING INSTRUCTIONS: SET DAY AND TIME: Place the Set Slide Switch into the DAY/TIME position. With the day flashing, press UP or DOWN to set the day of the week. Press NEXT and the clock time will start flashing. Use UP or DOWN to set the time, making sure the AM/PM indication is correct. - Page 21 pump has different operating characteristics, you should refer to your heat pump literature to determine when to disable the heat pump and run in Emergency Heat mode. LCD DISPLAY BACKLIGHT: The display screen is lighted to assist viewing at nighttime, or in locations with low light levels. A press of any button on the front panel will light the display for approximately 10 seconds.

Page 22: Temperature Programs
TEMPERATURE PROGRAMS: By default, this thermostat has 4 separate program periods for both Heat and Cool mode, they are: MORN, DAY, EVE, and NITE. Each period ends at the start time of the following period. The heat programs are set in HEAT mode, and the cool programs are set in COOL mode. -

remaining days, one after the other (specific days may be skipped by pressing the UP button to advance past them when they are flashing in the “copy to” location). To exit the Copy feature, and return to the regular temperature program screen, press and hold the NEXT button for more than 2 seconds. - Page 24 for heat pump configurations). An Offset value from 1 to 9 degrees will determine the number of degrees from the set point that will be required for the second heating stage to turn on. This setting can be used to conserve energy in situations where the second heating stage is more costly to operate when compared to the first stage.
- Page 25 TEMPERATURE CALIBRATION: The internal temperature sensor in this thermostat is accurately calibrated at the factory, and in most cases alterations to this setting should not be needed. The Temperature Calibration feature allows you to manually offset the measured temperature by as much as plus or minus 5°F (3°C) degrees from its original value. This feature can be useful to match or synchronize this thermostat to another one or more, if multiple thermostats are used in the same home.

- Page 27 NOTE: When activating the Special Program feature, button presses need to be performed in a timely manner, as the thermostat will timeout and automatically exit the setting screen after approximately 10 seconds without a button press. TO ACTIVATE THE SPECIAL PROGRAM: Press and hold the HOLD button for at least 5 seconds.

Do you have a question about the Smart Temp TX9100U and is the answer not in the manual?
Questions and answers
I replace the battery but it still says low battery
The Lux Products Smart Temp TX9100U may still show a low battery warning after replacing the battery if:
1. The batteries were not installed with the correct polarity.
2. Old or poor-quality batteries were used instead of new Energizer® or DURACELL® “AA” alkaline batteries.
3. The battery monitor setting (Switch #8) is turned off (ON/UP position), which disables battery monitoring.
4. The thermostat is not properly reassembled after battery replacement.
Check each of these factors to ensure proper operation.
