Change Temperature Settings - Lennox SignatureS
tat 81M26 Programming And Application Manual

IMPORTANT
Stress to the homeowner the importance of remembering the Secu-
rity Code if code is forgotten or misplaced, the universal code
4199" can be used. If the thermostat is reset, all schedules are
erased and full reprogramming is required.
After the security code is set, when any button on the thermostat is
pushed, a screen appears that requires the security code to be en-
tered. After the correct security code is entered, security is turned off.
After revisions are made to the settings, the user must reenter the
code to reestablish security

Change Temperature Settings

NOTE − If auto changeover is enabled at the time a temperature hold is
invoked, the thermostat MAY CHANGE OVER from heating to cooling and
vice versa, to maintain the temperature hold setpoint. The auto changeover
deadband is still used to determine whether changeover occurs. This
applies to all of the following hold modes.

UP or DOWN button. Press the
UP/DOWN buttons to adjust to
the desired temperature.
2. This setting will hold for 3 hours or
until the next programmmed
event begins, whichever time
period is shorter.
