While many of the items on the Main screen are view-only, you change the cool and heat setpoints, the H/C mode, and fan mode on
this screen. The following sections describe how to change items on the Main screen.

Changing the Heating and Cooling Setpoints

You can change the heating and cooling setpoints on the Main screen. Changing the setpoints places the thermostat in temporary
hold mode and uses the new temperature settings. The setpoints change back to the program mode setpoints at the next program
time. You cannot change the heating and cooling setpoints if the thermostat is in permanent hold mode. See the Changing Hold
Mode section on page 20 for more information about Hold modes.
1. On the Main screen, press either of the navigation buttons to access the heating or cooling setpoints that appear on the left
side of the screen. When either of the setpoints blinks, you can change the setpoint by using the navigational buttons to
increase or decrease its value.
2. Press Mode/Select to select the next setpoint, and use the navigational buttons to increase or decrease its value.
The setpoints continue to blink and are able to be changed until the thermostat reaches a 10-second timeout. Press and hold
Mode/Select for three seconds for changes to immediately take effect.
NOTE: Depending on the H/C mode you select, you may only see one setpoint on the Main screen. (If you turn off the HVAC system,
neither appears.) See the Changing the Heating/Cooling Mode section on page 21 for more information.

Changing Hold Mode

You can access Hold Mode by pressing and holding Mode/Select for three seconds. You can use the navigational buttons to scroll
through the list. You can also change the Hold mode on the Thermostat Mode screen.
