About Advanced Features & Operation

HEAT/COOL DIFFERENTIAL - The Heat and Cool setpoints will not be
allowed to come any closer to each other than the value set in Advanced
Setup step #8, on page 12. This minimum difference is enforced during
Auto changeover and Program On operation.

Note: To increase the spread between the heating and cooling setpoints,
press the MODE button until only the heat setpoint is displayed; adjust to
the desired setpoint. Press the MODE button until only the cool setpoint
is displayed; adjust to the desired setpoint. Press the MODE button again
to enter the Auto-changeover mode where both the heat and cool
setpoints are displayed.

MEMORY BACKUP - In the event of a power loss, the thermostat will retain
the stored program settings without external power or batteries.

SINGLE SETPOINT BEHAVIOR - When configured as a Single Setpoint
thermostat, page 11, step 3, the large number is the setpoint. In Auto
mode the deadband is above and below the setpoint. To avoid short
cycling in single setpoint it is recommended that the deadband be set
for at least 2 degrees, page 12, step 7.
