KEYPAD LOCKOUT: You can lock the front panel buttons to prevent unauthorized
tampering of your thermostat settings.
TO LOCK THE KEYPAD: Start with the thermostat at rest, and the display backlight
NOT illuminated. Press the NEXT button one time to illuminate the display
screen, then press the NEXT button 3 more times, followed by the HOLD button 1
time.
TO UNLOCK THE KEYPAD: Start with the thermostat at rest, and the display
backlight NOT illuminated. Press the NEXT button one time to illuminate the
display screen, then press the NEXT button 3 more times, followed by the HOLD
button 1 time.
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 SET and NEXT buttons
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, first ensure that the thermostat’s Keypad
Lockout is not enabled and then move the System Mode switch to the OFF
position. Start with the thermostat at rest, and the display backlight NOT
illuminated. Press any button one time to illuminate the display screen, and then
press and hold the NEXT and HOLD buttons together for at least 5 seconds.
NOTE: there will no visual confirmation on the display screen, however you
should be able to turn the cooling system on and off without any protection
delays being imposed. 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.
