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 (heat-  
ing, ventilation, and air conditioning) system. Separate heat-  
ing 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.  
Fig. 1 — Thermostat Display  
II. HEAT OR COOL INDICATOR  
IMPORTANT: The thermostat has a configurable security level.  
If certain functions are not available (changing set points, chang-  
ing programming schedules), the thermostat security level may  
be configured to exclude those functions. Call the installer to  
reconfigure the security level.  
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 ther-  
mostat is in Heating mode. The light will be green if the ther-  
mostat 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 cur-  
rent 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 ther-  
mostat is in AUTO mode, pressing the UP ARROW 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. Press-  
ing 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 Pro-  
gramming mode.  
Fig. 2 — Thermostat Front Panel Buttons  
B. Override Button  
The Override button is used to force the thermostat from Un-  
occupied 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.  
Fig. 3 — Thermostat Programming Buttons  
The set points are adjustable with the UP ARROW and DOWN  
ARROW keys during Override mode.  
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.  
NOTE: If the thermostat is in Occupied mode and the Over-  
ride button is pressed, the thermostat will go into Unoccu-  
pied mode immediately. The thermostat will remain in Un-  
occupied mode until the next Occupied start time.  
When the fan is not set to FAN ON (no icon displayed on ther-  
mostat screen), the fan will run during heating and cooling  
operation only.  
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 acces-  
sible from underneath the thermostat cover. To access the pro-  
gramming buttons, pull on the hinged thermostat cover. See  
Fig. 3. The programming buttons are: Mode, Fan, Holiday,  
Program, and Set Clock.  
C. Mode Button Operation  
The Mode button selects the operating mode of the thermo-  
stat. If OFF is selected, the thermostat will not enter Heat-  
ing or Cooling mode. If HEAT is 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 tempera-  
ture and the heating and cooling set points. If PROGRAM  
ON is selected, the stored schedule is enabled and the ther-  
mostat will follow the Occupied and Unoccupied schedules  
stored in its memory.  
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’’

1. The Copy command can be used to copy the previous  
day’s schedule if the schedules are the same. The copy  
command becomes available after all the occupied  
periods are programmed in a day. Use the UP ARROW  
to change the copy command to YES. Use the DOWN  
ARROW to change the copy command to NO. Press the  
Mode button when the choice has been made. See  
Fig. 7.  
12. After all the times and set points for each day have  
been entered, press the Program button to finish en-  
tering the schedule.  
NOTE: The thermostat will continue to follow the schedule  
until a new one is entered.  
If only one occupied schedule is selected, the Occupied 2  
and 3 schedules are skipped.  
If the start time is set later in the day than the stop time,  
the program will run from midnight of that day to the stop  
time and then from the start time to midnight.  
If NO was selected, the schedule will automatically  
change to the next day and the user must enter the oc-  
cupied and unoccupied schedules for that day.  
If the same start and stop times are programmed for an  
occupancy schedule, the thermostat will be in Occupied mode  
for 24 hours.  
NOTE: Occupied 1 schedule heating and cooling set points  
are the same for each day. Occupied 2 and 3 set points may  
be set to different values for each day of the week.  
If one occupied period starts or stops within another occu-  
pied period, the lower numbered schedule has priority. For  
example, if schedule Occupied 3 is running for 24 hours  
and occupied schedule 2 comes on from 1 to 3 PM, the set  
points from Occupied 2 are in effect from 1 to 3 PM.  
If YES was selected, the schedule will be copied to the  
next day. The schedule copy may be repeated until Sun-  
day is reached. The Sunday schedule cannot be copied  
to Monday.  
B. Overriding the Schedule  
The schedule can be overridden during operation by pressing  
the UP or DOWN ARROW buttons to change the desired tem-  
perature. The thermostat will use the new set point until the  
next scheduled time period starts.

be set from 1 to 99 days. The thermostat will enter Holiday  
mode on midnight of the next day after the mode has been  
activated. Holiday mode will remain in effect until midnight  
of the last configured day.  
II. TWO-STAGE OPERATION  
The second stage of heat or cool is turned on when the first  
stage has been on for a minimum of 2 minutes and the tem-  
perature differential from the set point is equal to or greater  
than the set point plus the deadband plus 2 degrees.  
III. CLOCK BACKUP  
In the event of a power loss, the thermostat will keep  
time for a minimum of 48 hours without external power or  
batteries.  
If the Holiday mode is in effect, the number of days remain-  
ing will blink on and off and the ‘‘Unoccupied’’ icon will be  
displayed. The Override button will be active during Holiday  
mode.  
IV. FAN OPERATION  
To turn off the Holiday mode before the remaining config-  
ured days have passed, press the Holiday button to enter the  
configuration mode. Press the DOWN ARROW to set the num-  
ber of days to zero. Holiday mode will be disabled.  
If Fan On is selected, the fan will run continuously during  
occupied schedule (except when Mode is switched to OFF).  
The fan will be off during unoccupied schedule except during  
heating or cooling operation.
