Lux Products P722Ua Thermostat User Manual


 
SOFTWARE RESET: A Software Reset is used to erase ALL heating and cooling
temperature programs, and to return all user-adjustable software settings back
to their original factory default values. To perform a Software Reset, first ensure
that the thermostat’s Keypad Lockout is not enabled and then move the System
Mode switch to the OFF position. Press and hold the UP, DOWN, and NEXT
buttons all together for at least 5 seconds. The LCD display screen will become
fully populated (let go of buttons at this point), and than return to normal. The
clock will have to be changed to match the current day and time.
COMPRESSOR PROTECTION BYPASS: This optional feature permits the installer
or service technician to temporarily disable the built in compressor protection
delays. This is most useful for diagnosing and testing the heating and cooling
systems after installation is complete, and should not be used during normal
operation. To activate this feature, press and hold both the NEXT and HOLD
buttons, while also perform a single press of the Hardware Reset button (the LCD
display screen will become fully populated). Continue to hold the NEXT and
HOLD buttons until the LCD display screen returns to normal. All compressor
protection delays (in all modes of operation) will be disabled for 5 minutes. After
the 5-minute duration has expired, the thermostat will return to normal operation
automatically.
