Bryant Commercial TSTATBBPCM01-A - Manual

IMPORTANT: Read entire instructions before programming
the thermostat.
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 al-
low occupied and unoccupied programming schedules for energy
savings.
All thermostats allow up to 4 time and temperature settings
to be programmed per 24-hr period. Each thermostat stores
programs for 7 independent days. Batteries are not required.
During power interruption the internal memory stores pro-
grams for an unlimited time.
OPERATION
I. THERMOSTAT DISPLAY
The thermostat display is located in the top center of the ther-
mostat. The following information can be displayed on the
screen:
• mode (OFF, EHEAT, COOL, AUTO, or HEAT)
• fan setting (ON or AUTO)
• hold status
• room temperature
• desired temperature
• clean filter status
• time of day
• day of the week
• schedule period (OC1, UN1, OC2, or UN2)
• outdoor temperature (optional)
II. 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 program-
ming buttons, pull on the hinged thermostat cover. See
Fig. 1. The programming buttons are: Copy Previous Day, Pro-
gram, Mode, Change Day, End Program, Fan, Set Time, Re-
set Filter, and Hold.
The Up and Down buttons are used to change the current,
desired temperature set point and to scroll through program-
ming set points. The Up and Down buttons are accessible from
the outside of the thermostat.
The daily schedule can be overridden in 2 ways: pressing the
Hold button, or pressing the Up and Down buttons to change
the temperature set point.
A. Programming Button Lockout
The thermostat has a lockout feature which will not acknowl-
edge programming buttons until the lockout code is entered.
After the lockout code has been entered, the keypad will re-
main unlocked until the user has stopped pressing buttons
for 2 minutes. The lockout feature is configured by the
installer.
NOTE: The lockout code sequence is Mode, Copy Previous Day,
Set Time, and Hold.
B. Hold Button Operation
Pressing the Hold button disables the time and temperature
schedule and holds the current desired temperature set point.
When a Hold is active, the HOLD annunciator is displayed
on the thermostat screen. To release the Hold, press the Hold
button a second time. The Hold will remain active for a du-
ration of 4 hours, or until a new time schedule starts.
C. Fan Button Operation
The Fan button selects fan operation. When the fan is set to
ON, the fan will run continuously for improved air circula-
tion. When the fan is set to AUTO, the fan will run during
heating and cooling operation only. During setback mode (UN1
and UN2) the fan will always be in AUTO mode.
D. Mode Button Operation
The Mode button selects the operating mode of the thermo-
stat. If OFF is selected, the thermostat will not enter heating
or cooling mode. If HEAT is selected, the thermostat will only
enter heating mode (if the room temperature is below the heat-
ing set point). If COOL is selected, the thermostat will only
enter cooling mode (if the room temperature is above the cool-
ing 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. Heat pumps also have an
EHEAT selection. If EHEAT is selected, the heat pump will
use the second stage of heating to provide heating, if neces-
sary. The annuciator for each selection will be displayed on
the thermostat when selected.
E. Auto-Changeover
When the thermostat mode is set to AUTO, the thermostat
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 tempera-
ture setting. The thermostat does not need to be manually
changed from heating to cooling or cooling to heating
operation.
NOTE: It is recommended that auto-changeover mode not be
used if the outdoor temperature is consistently lower than
50 F or greater than 80 F. In these cases, select heating or
cooling mode only.
F. Smart Recovery (Heating Mode)
The smart recovery function is designed to save energy by
gradually adjusting temperatures to meet scheduled set points.
The thermostat has 2 schedule modes, normal occupied mode
and setback mode (a time when the space is unoccupied). The
Smart Recovery function begins 1 to 1.5 hours before the sched-
uled occupied mode and gradually adjusts room temperature
so the temperature is at the occupied mode set point when
the occupied time period begins.
