III. SET CLOCK

The Mode and Override buttons are used to change the time
and day displayed on the thermostat. Press and hold the Mode
and Override buttons for 2 seconds to enter the setup screens.
The current time will blink on and off. Press the UP ARROW
and DOWN ARROW buttons until the correct time is shown.
Hold down the buttons to quickly move through the time dis-
play. The AM and PM annunciators will automatically change.
Hold down the Override button while pressing UP ARROW

or DOWN ARROW to change the time by hours instead of
minutes. To ensure the schedules are properly followed, make
sure that AM or PM is correct for the time chosen. When the
correct time is shown, press the Mode button to modify the
day of the week. The current day will blink on and off. Press
the UP ARROW and DOWN ARROW buttons until the cor-
rect day is shown. Press the Mode and Override buttons again
to exit the Set Clock mode.

IV. HEAT PUMP CONFIGURATION

To configure the thermostat for heat pump operation, Ad-
vanced Setup Steps 5 (Heat Pump Operation) and 6 (Revers-
ing Valve Polarity) must be configured correctly. See the
Configure Advanced Setup section for information on config-
uring these options.

NOTE:

Some large commercial rooftop heat pump units must

be configured with Advanced Setup Step 5 (Heat Pump Op-
eration) set to OFF. Refer to the base unit instructions for
more information.

V. CONFIGURE ADVANCED SETUP

To enter the advanced setup screens of the thermostat, press
the Mode and Override buttons at the same time for 5 sec-
onds. The Advanced Setup Step number is shown in the top
right corner of the thermostat screen. Use the Mode button
to advance through the steps. See Table 2. Press the Mode
and Override buttons at the same time to exit the Advanced
Setup mode.

NOTE:

Refer to Set Clock section on this page for an expla-

nation of Advanced Setup Steps 1 and 2.

A. Display Blanking (Step 3)

When Display Blanking is set to OFF, the thermostat will
display the time of day, current temperature, and mode nor-
mally. When Display Blanking is set to ON, the thermostat
will only display time of day. The default is OFF.

B. Fan Mode (Step 4)

The fan mode is used to configure fan operation. If On is se-
lected, the fan will run continuously during the Occupied sched-
ule (except when Mode is switched to OFF). The fan will be
off during unoccupied schedule except during heating or cool-
ing operation.

If Auto is selected, the fan will operate only during heating
or cooling operation. The default is Auto.
