Close to or in a frequently used room, preferably on an inside  
partitioning wall.  
INTRODUCTION  
Bryant thermostats are wall-mounted, low-voltage thermostats  
which maintain room temperature by controlling the operation of  
a heating and air conditioning system. Separate heating and  
cooling setpoints, plus auto changeover provide maximum comfort  
and flexibility. Batteries are optional; temperature and mode  
settings are preserved with the power off.  
On a section of wall without pipes or duct work.  
Thermostat should NOT be mounted:  
Close to a window, on an outside wall, or next to a door leading  
to the outside.  
Exposed to direct light and heat from a lamp, sun, fireplace, or  
other temperature-radiating object which may cause a false  
reading.  
INSTALLATION CONSIDERATIONS  
POWER  
Note that all thermostats are dual powered where batteries can be  
installed or in the presence of R and C (24vac) are not required. 2  
AA batteries are furnished with the product.  
Close to or in direct airflow from supply registers and return-air  
grilles.  
In areas with poor air circulation, such as behind a door or in  
an alcove.  
MODELS  
There are 3 different models. The 9th and 10th letters of the part  
number indicate the model. These 2 letters also appear on the  
package and on the circuit board. Be sure to have the proper  
thermostat for the intended application. Models are:  
AC — 1-stage cool, 1-stage heat for AC systems only.  
HP — 1-stage cool, 2-stage heat for either HP, or AC with 2-stage  
heat.  
II. SELECT MODEL  
AC Model (1-stage cool, 1-stage heat) is to be used for single-  
stage heating and/or cooling applications only. It CANNOT be  
used with optional outdoor temperature sensor. (See Table 1.)  
HP Model (1-stage cool, 2-stage heat) can be used with a  
single-speed heat pump (HP), or an air conditioner (AC) with a  
2-stage furnace or fan coil. Software Option 5 selects HP/AC  
operation. This thermostat comes configured from the factory as a  
heat pump thermostat. Select AC in software Option 5 for AC  
operation. When AC operation is selected, the O/W2 terminal is  
converted from a reversing valve output (O) to a second-stage heat  
output (W2). This output can be used to control 2-stage furnaces or  
2

. Turn OFF all power to unit.  
IV. SET THERMOSTAT CONFIGURATION  
. If an existing thermostat is being replaced:  
a. Remove existing thermostat from wall.  
Configuration options are intended to be selected at installation  
and are normally not modified by the home owner. These options  
are not discussed in the Homeowner’s Guide and therefore must be  
made as part of the installation. A special procedure allows entry  
into the configuration mode. The thermostat will automatically exit  
this mode if no button is pressed for 3 minutes. While in the  
configuration mode, up to 14 option choices can be made:  
b. Disconnect wires from existing thermostat, 1 at a time.  
Be careful not to allow wires to fall back into the wall.  
c. As each wire is disconnected, record wire color and  
terminal marking.  
d. Discard or recycle old thermostat.  
Option 01: Anticipator setting  
Option 02: Clean filter setting  
NOTE: Mercury is a hazardous waste and MUST be disposed of  
properly.  
Option 03: Fahrenheit or Celsius selection  
Option 04: Enable fan (G) on with W/W1 output  
Option 05: HP / AC  
Option 06: Cooling Lockout (available only if an outdoor air  
temperature sensor is present)  
3
. Open thermostat (mounting base) to expose mounting  
holes. The base can be removed to simplify mounting. Snap  
apart carefully to separate mounting base from remainder of  
thermostat.  
NOTE: If thermostat will not separate, insert a small screwdriver  
into top slots for ease of opening.  
Option 07: Enable zoning  
Option 08: Auxiliary heat lockout temperature adjustment (avail-  
able only on heat pump systems and if an outdoor air temperature  
sensor is present)  
Option 10: O (reversing valve) ON with Heat or Cool (present on  
Heat Pump models only)  
4
. Route thermostat wires through large hole in mounting  
base. Level mounting base against wall (for aesthetic value  
only—thermostat need not be leveled for proper operation)  
and mark wall through 2 mounting holes.  
5
6
. Drill two 3/16-in. mounting holes in wall where marked.  
Option 13: Room temperature offset adjustment  
Option 15: Enable AUTO mode  
Option 18: Backlight configuration  
Option 19: Equipment Present  
. Secure mounting base to wall with 2 anchors and screws  
provided, (additional anchoring holes available for more  
secure mounting if needed) making sure all wires extend  
through hole in mounting base.  
Option 21: Keypad Lockout  
An explanation for each of these and how to enter the configura-  
tion mode follows.  
7
8
. Adjust length and routing of each wire to reach proper  
terminal and connector block on mounting base with 1/4 in.  
extra wire. Strip only 1/4 in. insulation from each wire to  
prevent adjacent wires from shorting together when con-  
nected.  
TO ENTER THE CONFIGURATION MODE:  
To enter Configuration Mode, hold the FAN button down for  
approximately 15 seconds. After the 15 second period, Option  
01will appear in the display and the SERVICE icon will be  
turned on.  
. Match and connect equipment wires to proper terminals of  
the connector blocks. (See Table 1.)  
NOTE: If the FAN button is pressed again or if no button is  
pressed for 3 min, the thermostat will exit the configuration mode  
and return to normal operation. To reenter the configuration mode,  
the FAN button must be pressed and held for 15 seconds again.  
CAUTION: ELECTRICAL OPERATION HAZARD  
Failure to follow this caution may result in equipment  
damage or improper operation.  
Improper wiring or installation may damage the thermo-  
stat. Check to make sure wiring is correct before proceed-  
ing with installation or turning on unit.  
WHILE IN CONFIGURATION MODE:  
The display is used to show both the option number and the  
selection choice within that option.  
A. Option 01—Anticipator Adjustment  
9
. Push any excess wire into wall and against mounting base.  
Seal hole in wall to prevent air leaks. Leaks can affect  
operation.  
This adjustment controls the sensitivity and cycle rate of the  
thermostat. Higher numbers decrease the sensitivity and slow the  
cycle rate. Lower numbers increase sensitivity and increase cycle  
2—  
rate. However, a limiting feature will not allow more than 6  
equipment cycles per hour, regardless of setting. Values can range  
from 1 to 9. Factory default setting is 3. This default selection will  
provide optimum performance in nearly all installations. Try it  
first. Do not change setting unless there is evidence of need to do  
so.  
D. Option 04—G (Fan) On With W/W1 Output  
This selection determines whether the G (fan) output is to be ON  
or OFF when any W (furnace or strip heat) output is ON. Most  
furnaces and fan coils manage their own blowers and do not  
require a separate G signal. For these applications, select OFF.  
Some auxiliary heaters require a separate G signal to turn on the  
blower. In this case, select On. Factory default is OF (off).  
Unlike conventional anticipators, this setting is not to be deter-  
mined by current draw. There is no need to measure, know, or  
compensate for current. There is also no droop with this thermo-  
stat, regardless of anticipator setting. This adjustment controls only  
sensitivity and cycle rate up to the maximum of 6 cycles per hr.

OPERATIONAL INFORMATION  
FIVE-MINUTE COMPRESSOR TIMEGUARD  
This timer prevents the compressor from starting unless it has been off for at least 5 minutes. It can be defeated for 1 cycle by simultaneously  
pressing the FAN mode button and the INCREASE TEMPERATURE button.  
FIFTEEN-MINUTE CYCLE TIMER  
This timer prevents the start of a heating or cooling cycle until at least 15 minutes after the last start of the same cycle. Its function is to assure  
that equipment is not cycled more than 4 times per hr. This timer is defeated for 1 cycle when the desired temperature is manually changed. It  
can also be defeated for 1 cycle by simultaneously pressing the FAN mode button and the INCREASE TEMPERATURE button.  
FIFTEEN-MINUTE STAGING TIMER  
In multistage heating or cooling, this timer prevents any higher stage from turning on until the preceding stage has been on for 15 minutes. This  
timer is defeated if the temperature error is greater than 5°F (usually due to a large change in desired temperature).  
THREE-MINUTE MINIMUM ON TIME  
In normal operation, when a stage turns on, it will not turn off for a minimum of 3 minutes.  
HEAT/COOL SET POINTS (DESIRED TEMPERATURES)  
A minimum difference of 2°F is enforced between heating and cooling set points. This is done by allowing one setting to "push" the other, to  
maintain this difference.  
AUTO CHANGEOVER  
When the auto changeover mode is selected, a change from heat to cool (or vice versa) will not occur until an opposite mode demand has existed  
for 20 minutes. If the set point is changed, the 20 minute requirement is deleted. Auto mode may be disabled.  
EMERGENCY HEAT MODE  
When thermostat is configured as a heat pump and emergency heat mode is selected, all Y signals are locked out and W becomes energized upon  
a call for heat.  
HEAT ON AND COOL ON ICONS  
When a heating or cooling demand exists, the HEAT ON or COOL ON icon will either remain on or flash. If flashing, the equipment is temporarily  
prevented from turning on by one of the timers (see above). While the icon remains on without flashing, the equipment is on.  
POWER ON CHECK  
When AC power is first applied, all segments of the display are turned on for a few sec. Following this, the temperature display indicates the  
model/configuration via the following 2 digit code:  
AC—1-speed air conditioner, HP—1-speed heat pump, A2—2-speed air conditioner, H2—2-speed heat pump.  
ERROR CODES  
-- — If the thermostat cannot properly read room temperature, the display will indicate -- (2 dashes) and all outputs (except the fan if on) will  
turn off. This is to prevent operation of the equipment if the thermostat has failed.  
E2 — If the AC line voltage drops below a minimum (brownout) level, all outputs are turned off and the display indicates E2. This condition will  
remain for 15 sec after proper line voltage is restored. If the AC line voltage disappears completely, the display will immediately go blank.  
E3 — If the thermostat cannot properly read outdoor temperature, and it is needed for proper operation (Heat pump system and Option 8 is not  
set to OF), E3 will flash alternately with room temperature.  
THERMOSTAT TROUBLESHOOTING  
SYMPTOM  
Blank LCD  
WHAT TO CHECK  
Check for 24vac between R and C at terminal connections or battery.  
Temperature sensor reading out of range. Check sensor for damage. If recycling power  
does not clear display, thermostat should be replaced.  
"--" (2 dashes) on temperature display  
Brownout condition or too low of voltage to thermostat. Double check wiring and check for  
"
E2" on temperature display  
E3" on temperature display  
24vac between R and C. E2 will clear 15 sec after proper voltage is restored.  
"
The outdoor temperature sensor is open, not connected, or shorted.  
After the selected number of hour of blower operation "FILTER" will display on LCD. This  
is to remind the home owner to "check" the filter. Press RESET FILTER button to clear  
display and reset timer to 0.  
"SERVICE FILTER" on temperature display  
Select COOL mode. Set desired temperature to 10°F below room temperature. Simulta-  
neously press FAN and INCREASE TEMPERATURE buttons to defeat timers. Check for  
COOL ON icon and 24vac at Y (first-stage) terminal. If present, thermostat is OK and  
problem is with equipment or wiring. If not present, replace thermostat.  
Cooling will not come on  
Select HEAT mode. Set desired temperature to 10°F above room temperature. Simulta-  
neously press FAN and INCREASE TEMPERATURE buttons to defeat timers. Check for  
HEAT ON and 24vac at Y (first-stage) terminal (with heat pump) or W/W1 (with air condi-  
tioner) terminal. If present, thermostat is OK and problem is with equipment or wiring. If  
not present, replace thermostat.
