Lux Products 52126 Thermostat User Manual


 
UP / DOWN BUTTONS: The UP and DOWN buttons are used to adjust any
item that can be changed by the user. Examples are the set temperatures,
clock times, and days of the week. In many cases, an item may be
flashing if it can currently be adjusted.
HOLD BUTTON: This button activates and deactivates the manual
Temperature Hold feature.
EMER BUTTON: When in Normal Run mode, the usage of this button
varies depending upon your specific system configuration. For heat pump
systems, pressing this button enables your emergency heat function,
which is described in greater detail in the OPERATING INSTRUCTIONS
section. For conventional systems, there is no such thing as emergency
heat, so this button will have no effect.
NEXT BUTTON: This button is mostly used while setting items such as
software options, and temperature program periods. When there are
several items on the screen that can be changed, usually one of them is
flashing indicating that it can be adjusted. Pressing the NEXT button will
cycle through which item is flashing.
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.
Holding the UP or DOWN buttons will make the clock digits scroll rapidly.
Return the Set Slide switch to the RUN position when finished.
