Bryant TEMPSURE TSTATBBP250-LA - Manual (Page 6)

11. 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 pe-
riods are programmed in a day. Use the UP ARROW to
change the copy command to YES. Use the DOWN AR-
ROW to change the copy command to NO. Press the
Mode button when the choice has been made. See
Fig. 7.
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.
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 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.
12. After all the times and set points for each day have
been entered, press the Program button to exit pro-
gramming mode.
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 the same start and stop times are programmed
for an occupancy schedule, the thermostat will be in Occu-
pied mode for 24 hours. If one occupied period starts or stops
within another occupied period, the lower numbered sched-
ule has priority. For example, if schedule Occupied 3 is run-
ning for 24 hours and Occupied 2 schedule comes on from 1
to 3 PM, the set points from Occupied 2 are in effect from 1 to
3 PM.
B. Overriding the Schedule
The schedule can be overridden by pressing the UP or DOWN
ARROW buttons to change the desired temperature. The ther-
mostat will use the new set point until the next scheduled
time period starts.
VII. CALIBRATE TEMPERATURE SENSOR
Every thermostat is factory calibrated. Under normal circum-
stances there will never be a need to re-calibrate the ther-
mostat. If re-calibration must be done, perform the following
procedure:
1. Hold down the Mode and Fan buttons for 5 seconds. All
of the icons on the display screen will appear. Release
the buttons. Press the UP and DOWN ARROW buttons
simultaneously.
2. Press the UP and DOWN ARROW buttons simulta-
neously again. The current temperature will be
displayed.
3. Use an accurate thermometer to measure room tem-
perature. Press the UP or DOWN ARROW buttons un-
til the flashing number equals room temperature.
4. Press the Mode button to return to normal operation.
IX. LIGHT SENSOR ADJUSTMENT
The light sensor is used for light-activated operation. The sen-
sor can be adjusted for a variable degree of sensitivity. The
sensitivity adjustment screw is located on the inner cover of
the thermostat, near the DOWN ARROW button. Turning the
screw clockwise increases the sensitivity of the sensor to light.
Turning the screw counterclockwise decreases the sensitivity
of the sensor to light.
To check for correct sensitivity, place the thermostat in Pro-
gram On mode. The thermostat should be in Occupied 1 when
the lights are on. If the sensor does not enter Occupied 1 while
the lights are on, turn the screw clockwise until the Occu-
pied 1 icon appears on the display. The thermostat should
enter Unoccupied mode when the lights are off. If the sensor
does not enter Unoccupied when the lights are turned off, turn
the screw counterclockwise until the Unoccupied icon ap-
pears on the display.
IMPORTANT: An external device should not be used with the
dry contact switch with light activated operation. The light
sensor is wired to the dry contact switch. Another device will
cause conflicting signals to the thermostat. The RED wire of
the sensor is wired to CK1. The BLACK wire of the sensor is
wired to CK2.
X. CHECK THERMOSTAT OPERATION
To check thermostat operation, perform the following
procedure:
1. Press the Mode button repeatedly until the Heat icon
appears on the display. The thermostat is now in Heat-
ing mode.
2. Press the Fan button. The Fan Auto icon will appear on
the display screen. Press the UP ARROW button until
the heating set point is 10 F (6 C) higher than the cur-
rent room temperature. Heating and fan should be
energized.
3. Press the Mode button repeatedly until the Cool icon ap-
pears on the display. The thermostat is now in Cooling
mode.
4. Press the DOWN ARROW button until the cooling set
point is 10 F lower than the current room temperature.
Cooling and fan should be energized.
5. Press the Mode button repeatedly until the Off icon ap-
pears. Press the Fan button until the display reads Fan
On. The fan should energize.
6. If heating, cooling, or fan operation do not energize, check
wiring and consult Table 4.
XI. FINAL CHECKLIST
1. Put away tools and instruments. Clean up debris and
packaging.
2. Review Owner’s Guide with occupant or owner.
3. Leave the manuals with owner.
