Changing the Temperature Setpoints

Change the temperature setpoints by pressing the

✞!or ✟!buttons to lower or raise

the displayed setpoint. Pressing the buttons once will display only the current set-

points that the thermostat is controlling. Press and hold to change the value.

To access a setpoint, the thermostat must be in a mode of operation where the set-

point would be used (e.g., to change the heat setpoint, the thermostat must be in

either the heat or auto mode). The mode symbol for the setpoint being displayed (%

for heat and ☛ for cool) will also appear. When in the auto mode, the thermostat will

first display either of the two setpoints, heat or cool. To view or change the opposite

setpoint, press the MODE button.

Press the

✞! and ✟! buttons simultaneously to change the displayed temperature

from Celsius (°C ) to Fahrenheit (°F), and vice versa.

12 or 24 Hour Clock
