reminders are not enabled until you activate them. To do so,
press the Settings button (shown below the Fan button in
figure 17) once or twice for the desired reminder as shown
in figure 18 and as described in table 1.

SETTINGS - Balance Point

NOTE: NOTE - The balance point is only available with the
outdoor sensor.
If the optional outdoor sensor (X2658) is connected to
the thermostat, balance point adjustment is available.
The balance point feature allows the measured outdoor
temperature to govern operation of the heat pump and
backup heat source.
Use the SETTINGS button to access the balance point
setting. If the outdoor sensor is attached to the thermostat,
press the SETTINGS button three times to access the
Balance Point Settings screen (see figure 20).
Figure 20. Balance Point Settings
The balance point can be set at any temperature between
1°F and 55°F (-17°C to 13°C). A balance point setting of
zero disables the balance point function (in this case, the
thermostat behaves as if no outdoor sensor is attached).
The default balance point setting is 55°F. To adjust the
balance point up or down, press the Up/Down arrow buttons
to the right of the display screen. The balance point setting
increases by 1°F each time the Up button is pressed and
decreases by 1°F each time the Down button is pressed.
After the desired balance point is reached, the HOME
screen will reappear after about 15 seconds.
NOTE: The balance point feature allows the outdoor
temperature to rise or fall 3°F above or below the
balance point. This prevents excessive cycling of
the equipment when the outdoor temperature is
near the balance point. For example, if the balance
