GENERAL
Bryant’s 7-day, commercial, programmable thermostats are
wall-mounted, low-voltage thermostats which maintain room
temperature by controlling the operation of an HVAC (heating, ventilation, and air conditioning) system. Separate heating and cooling set points and auto-changeover capability
allow occupied and unoccupied programming schedules for
energy savings.
All thermostats allow up to 3 occupied and one unoccupied
time/temperature setting to be programmed per 24-hour
period. Each thermostat stores programs for 7 independent
days. Batteries are not required. During power interruption
the internal NEVERLOST™ memory stores programs for an
unlimited time.
CONFIGURATION
I. THERMOSTAT DISPLAY
The thermostat display is located in the center of the thermostat. See Fig. 1. The following information can be displayed on the screen:
• mode (OFF, HEAT, COOL, AUTO, or PROGRAM ON)
• fan setting (FAN ON or blank)
• override indication
• room temperature
• desired temperature
• service filter indicator
• time of day
• day of the week
• schedule period (Occupied 1, 2, or 3; or Unoccupied)
• setup indicator (programming mode)
• lock indicator
• start/stop indicator (schedule period program mode)

IMPORTANT: Thethermostathasaconfigurable security level.
If certain functions are notavailable (changing set points, changing programming schedules), the thermostat security level may
be configured to exclude those functions. Call the installer to
reconfigure the security level.
II. HEAT OR COOL INDICATOR
A Heat or Cool indicator is located on the bottom left cover of
the thermostat. See Fig. 2. The light will be red if the thermostat is in Heating mode. The light will be green if the thermostat is in Cooling mode.
III. THERMOSTAT FRONT PANEL BUTTONS
The thermostat has buttons on the front cover which are used
to raise or lower the desired set point and override the current program. See Fig. 2.
A. Set Point Buttons
The UP ARROW and DOWN ARROW buttons will raise or
lower the current desired temperature set point. If the thermostat is inAUTO mode, pressing the UPARROW or DOWN
ARROW buttons will adjust both the heating and cooling set
points. Pressing the UP ARROW or DOWN ARROW buttons
in Cooling mode will adjust only the cooling set points. Pressing the UP ARROW or DOWN ARROW buttons in Heating
mode will adjust only the heating set points. The UP
ARROW and DOWN ARROW buttons are also used in Programming mode.
B. Override Button
The Override button is used to force the thermostat from Unoccupied mode into the Occupied 1 mode comfort settings. The
Override period will be set at 30 minutes. The thermostat
will then return to Unoccupied mode. To increase the amount
of time in Override mode, press the Override button again.
Thirty minutes of override time will be added for each time
the Override button is pressed up to a maximum of 4 hours.
After the 4-hour limit has been reached, press the Override
button again to cancel Override mode.
While in Override mode, the Override icon and the
Occupied 1 icon will be displayed on the thermostat. The time
of day and the minutes remaining in Override mode will
alternate on the thermostat display.
The set points are adjustable with the UPARROW and DOWN
ARROW keys during Override mode.
NOTE: If the thermostat is in Occupied mode and the Override button is pressed, the thermostat will go into Unoccupied mode immediately. The thermostat will remain in Unoccupied mode until the next Occupied start time.
IV. THERMOSTAT PROGRAMMING BUTTONS
The thermostat has programming buttons which are used
to change the set points of the thermostat, set the modes, and
program schedules. The programming buttons are accessible from underneath the thermostat cover. To access the programming buttons, pull on the hinged thermostat cover. See
Fig. 3. The programming buttons are: Mode, Fan, Holiday,
Program, and Set Clock.
The UP ARROW and DOWN ARROW buttons are used to
scroll through programming set points. The buttons are also
used to answer yes or no.
A. Keypad Lock
The thermostat has a keypad lockout feature which will not
acknowledge front panel buttons until the lockout sequence
is entered. To disable or lock the keypad, press and hold the
Mode button. While holding down the Mode button, press the
UP and DOWN ARROW buttons simultaneously.The ‘‘Locked’’
icon will appear on the display.
The thermostat is unlocked by performing the same procedure. Press and hold the Mode button. While holding down
the Mode button, press the Up and Down Arrow buttons
simultaneously. The ‘‘Locked’’ icon will be removed from the
display.
B. Fan Button Operation
The Fan button selects fan operation. When the fan is set to
FAN ON, the fan will run continuously for improved air
circulation.
Fig. 2 — Thermostat Front Panel Buttons
Fig. 3 — Thermostat Programming Buttons
NOTE: When the thermostat is in Unoccupied mode, the fan
will run only during heating or cooling operation, even if the
fan is set to FAN ON; this is the energy-saving smart fan
feature.
When the fan is not set to FAN ON (no icon displayed on thermostat screen), the fan will run during heating and cooling
operation only.
C. Mode Button Operation
The Mode button selects the operating mode of the thermostat. If OFF is selected, the thermostat will not enter Heating or Cooling mode. If HEATis selected, the thermostat will
only enter Heating mode (if the room temperature is below
the heating set point). If COOL is selected, the thermostat
will only enter Cooling mode (if the room temperature is above
the cooling set point). If AUTO is selected, the thermostat will
enter Heating or Cooling mode based on the room temperature and the heating and cooling set points. If PROGRAM
ON is selected, the stored schedule is enabled and the thermostat will follow the Occupied and Unoccupied schedules
stored in its memory.
Auto-Changeover
When the thermostat mode is set to AUTO, the thermo-
stat will provide automatic changeover from Heating to Cooling mode and Cooling to Heating mode when required. The
thermostat will automatically switch to maintain the desired
temperature setting. The thermostat does not need to be manually changed from heating to cooling or cooling to heating
operation.
D. Holiday Mode
The Holiday button places the thermostat into Holiday mode.
During Holiday mode, the unoccupied set points are
enforced. The number of days the thermostat will be in Holiday mode can be set.

V. SET CLOCK
The Set Clock button allows the user to change the time and
day displayed on the thermostat. Press the Set Clock button
to enter Set Time mode. See Fig. 4. 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 display. The AM and
PM annunciators will automatically change. To scroll through
by hours only,press and hold down the Fan button while pressing the UP or DOWN ARROW buttons. 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
DOWNARROW buttons until the correct day is shown. Press
the Set Clock button again to exit the Set Time mode.

VI. PROGRAMMING THERMOSTAT SCHEDULES
Before programming the thermostat, plan the thermostat daily
schedule. The schedule is divided into 7 days (Monday through
Sunday). Each day can have 2 (Occupied 1, Unoccupied),
3 (Occupied 1, Occupied 2, Unoccupied), or 4 (Occupied 1,
Occupied 2, Occupied 3, Unoccupied) time periods. Each
occupied time period has a start time, stop time, heating set
point and a cooling set point. The unoccupied time period has
a heating set point and a cooling set point. The unoccupied
time period is active whenever an occupied time period is not
active. Fill in Table 1 below as an aid to programming the
daily schedules.
A. Programming Mode
To program the daily schedules, perform the following
procedure:
1. Enter programming mode by pressing the Program button. The Occupied 1 annunciator will appear on the thermostat display. See Fig. 5. Use the UP ARROW and
DOWN ARROW buttons to set the maximum number
of Occupied periods available. The thermostat can be
set to 1, 2, or 3. After the number of Occupied periods
has been selected, press the Mode button.
2. The cooling set point for Occupied 1 will be displayed.
Use the UP ARROW and DOWN ARROW buttons to
raise or lower the cooling set point until the desired
temperature is shown. The range of acceptable values
is 35 to 99 F (1 to 37 C). Press the Mode button to continue. See Fig. 5.
3. The heating set point for Occupied 1 will be displayed.
Use the UP ARROW and DOWN ARROW buttons to
raise or lower the heating set point until the desired
temperature is shown. The range of acceptable values
is 35 to 99 F (1 to 37 C). Press the Mode button to continue. See Fig. 5.
