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.
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.
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.
2S — 2-stage cool, 2-stage heat for 2-speed AC systems, or 2-stage cool, 3-stage heat for 2-speed HP systems.
USE EACH ONLY FOR ITS INTENDED PURPOSE. SEE TABLE 1.

•Close to or in a frequently used room, preferably on an inside partitioning wall.
•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.
•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.
II. SELECT MODEL
AC Model (1-stage cool, 1-stage heat) is to be used for singlestage 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-stage electric heat in fan coils. (See Table 1.)
2S Model is for 2-speed compressor systems only (HP and AC). Output Y1 controls compressor low speed and output Y/Y2 controls compressor high speed. (See Table 1.)

III. INSTALL THERMOSTAT
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.
1.Turn OFF all power to unit.
2.If an existing thermostat is being replaced:
a.Remove existing thermostat from wall.
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.
NOTE: Mercury is a hazardous waste and MUST be disposed of properly.
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.
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.Drill two 3/16-in. mounting holes in wall where marked.
6.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.
7.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 connected.
8.Match and connect equipment wires to proper terminals of the connector blocks. (See Table 1.)
CAUTION: ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Improper wiring or installation may damage the thermostat. Check to make sure wiring is correct before proceeding with installation or turning on unit.
9.Push any excess wire into wall and against mounting base. Seal hole in wall to prevent air leaks. Leaks can affect operation.
10.Snap case back together.
11.Close thermostat assembly making sure pins on back of circuit board align with sockets in connector.
12.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.
IV. SET THERMOSTAT CONFIGURATION
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:
Option 01: Anticipator setting Option 02: Clean filter setting
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)
Option 07: Enable zoning
Option 08: Auxiliary heat lockout temperature adjustment (available 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)
Option 13: Room temperature offset adjustment Option 15: Enable AUTO mode
Option 18: Backlight configuration Option 19: Equipment Present Option 21: Keypad Lockout
An explanation for each of these and how to enter the configuration mode follows.
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.
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.
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
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

The selected number is the number of degrees, plus or minus, which will be added to the actual temperature. The number can range between -5 and +5. Factory
—4—
default is 0. This adjusted value will be used as actual temperature for both display and control action. For example, if 2 is selected, 72°F actual will read 74°F. If setpoint is 72, the room will control to an actual value of 70 which will be displayed and acted upon as if it were 72. The effect is that a positive number selection will make the room temperature lower and vice versa. This thermostat is factory calibrated within an accuracy of plus or minus 1°F, so this adjustment will provide the best accuracy when set to 0.
