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 (heating, ventilation, and air conditioning) system. Separate heating and cooling set points and auto-changeover capability allow occupiedandunoccupiedprogramming 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 programs for an unlimited time.
OPERATION
I. THERMOSTAT DISPLAY
The thermostat display is located in the top center of the thermostat. 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. Toaccess the programming buttons, pull on the hinged thermostat cover. See
Fig. 1. The programming buttons are: Copy Previous Day, Program, Mode, Change Day, End Program, Fan, Set Time, Reset Filter, and Hold.
The Up and Down buttons are used to change the current,
desired temperature set point and to scroll through programming 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 acknowledge programming buttons until the lockout code is entered.
After the lockout code has been entered, the keypad will remain unlocked until the user has stopped pressing buttons
for 2 minutes. The lockout feature is configured by the
installer.
NOTE: Thelockout 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 duration 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 circulation. 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 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. 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 necessary. 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 temperature 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 scheduled occupied mode and gradually adjusts room temperature
so the temperature is at the occupied mode set point when
the occupied time period begins.

This is more efficient than making the system run at full capacity until the desired temperature is met.
NOTE: Smart Recovery does not apply to cooling operation.
III. SET CURRENT DAY
The Change Day button will change the day shown on the
thermostat display to the next day. If a schedule has been
entered, the thermostat will follow the schedule of the new
selected day.
IV. SET CURRENT TIME
The Set Time button allows the user to change the time displayed on the thermostat. Press the Set Time button. The display will show the SET TIME annunciator. Press the Up and
Down 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 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 Set Time button again to exit the Set Time
mode.
V. RESET FILTER
The Reset Filter button is used to clear the 9Clean Filter9 icon
on the display screen. The 9Clean Filter9 icon reminds the
user when it is time to change or clean the filter of the unit.
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 has 4 time periods (OC1, UN1, OC2, UN2).
Each time period has a start time, heating set point, and cool-
ing set point. Fill in Table 1 on page 3 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 PROGRAMMING annunciator will appear on
the thermostat display. The first day of the schedule
(MON) will be displayed and the first programming time
period (OC1) of that day will be displayed. The SET TIME
annunciator is also displayed.
NOTE: If a programming button is not pushed for 60 seconds, the thermostat will exit programming mode and any
changes made will be saved.
2. Press the Up and Down buttons to set the start time for
the schedule day and period shown (MON, OC1).
3. Press the Program button once the correct time is shown.
The SET TIME annunciator will turn off and the SET
DESIRED TEMP annunciator will be displayed.
4. The heating and cooling set points can now be programmed. The HEAT and COOL annunciators are displayed for the heating and cooling set points respectively.
The mode button is used to toggle between the heating
and cooling set points. Use the Up and Down buttons to
raise and lower the temperature set points.
NOTE: There must be at least 3 degrees difference between
the cooling and heating set points. The thermostat will automatically change any set points closer than 3 degrees.
5. Press the Program button to advance to the next time
period (UN1).
