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

S — 2-stage cool, 2-stage heat for 2-speed AC systems, or

-stage cool, 3-stage heat for 2-speed HP systems.

USE EACH ONLY FOR ITS INTENDED PURPOSE. SEE

TABLE 1.

III. INSTALL THERMOSTAT

10. Snap case back together.

1. Close thermostat assembly making sure pins on back of

circuit board align with sockets in connector.

WARNING: ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal

injury or death.

Before installing thermostat, turn off all power to unit.

There may be more than 1 power disconnect.

2. Turn ON power to unit.

NOTE: If a common wire has not been connected, two AA

batteries must be used to power the thermostat.

On power up, LCD readout will display AC, HP, A2, or H2

depending on the thermostat model status. See "Power On Check"

under "Operational Information" on page 11 for explanation.

. 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)

. 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)

. 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.

. 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.

. 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

″01″ will 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

. 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

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.

WIRING DIAGRAM NOTES:

. Furnace must control its own second-stage heat operation via furnace control algorithm. Refer to indoor equipment Installation Instructions

for proper setup.

. See Option 5 information to convert HP and 2S thermostats to AC thermostat operation.

. As an option, lock the furnace into low-heat operation and let O/W2/B control high-heat operation. Refer to indoor equipment Installation

Instructions for proper setup.

. O/W2/B can control second-stage heat. Refer to indoor equipment Installation Instructions for proper setup.

. Refer to outdoor equipment Installation Instructions for latent kit requirements (if any).

. Terminals marked with * may not be present on equipment.

. O/W2/B energizes reversing valve in cooling or heating. See Option 10.

. Refer to outdoor equipment Installation Instructions for proper setup.

. If system is wired per diagram, the ACRDJ (jumper) on furnace control board should be removed to allow thermostat to control outdoor

unit staging.

0. Refer to fan coil Installation Instructions for proper wiring.

1. If batteries are installed, C (common wire) is not required between indoor unit and thermostat.

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.
