Bryant TSTATBBPCM01-A - Manual

IMPORTANT:

Read entire instructions before starting the

installation.

SAFETY CONSIDERATIONS

Read and follow manufacturer instructions carefully. Follow
all local electrical codes during installation. All wiring must
conform to local and national electrical codes. Improper wir-
ing or installation may damage thermostat.

Recognize safety information. This is the safety alert symbol

. When the safety alert symbol is present on equipment

or in the instruction manual, be alert to the potential for per-
sonal injury.

Understand the signal words DANGER, WARNING, and CAU-
TION. These words are used with the safety alert symbol.
DANGER identifies the most serious hazards which will re-
sult in severe personal injury or death. WARNING signifies
a hazard which could result in personal injury or death. CAU-
TION is used to identify unsafe practices which would result
in minor personal injury or property damage.

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 (heat-
ing, cooling and ventilation) system. Separate heating and
cooling set points and auto-changeover capability allow occu-
pied and unoccupied programming for energy savings.

All thermostats allow up to 4 time/temperature settings to
be programmed per 24-hr period. Each thermostat stores pro-
grams for 7 independent days. Batteries are not required. Dur-
ing power interruption the internal memory stores comfort
schedules for an unlimited time while the clock continues to
run for at least 72 hours.

The thermostat can be configured to accept several different
equipment configurations, from single-stage heating and cool-
ing to 3 stages of heating and 2 stages of cooling. The ther-
mostat comes factory configured for 1 stage of cooling and
1 stage of heating.

INSTALLATION

I. THERMOSTAT LOCATION

The thermostat should be mounted:
• approximately 5 ft from the floor
• close to or in a frequently used room, preferably on an in-

side partitioning wall

• on a section of wall without pipes or ductwork

The thermostat should not be mounted:
• close to a window, on an outside wall, or next to a door

leading to the outside

• where exposed to direct light and heat from a lamp, the

sun, a fireplace, or any other temperature-radiating object
which may cause a false reading

• close to or in direct airflow from supply registers or return

air grilles

• in areas with poor air circulation (such as behind a door or

in an alcove)

II. SET DIP SWITCHES

There are 4 small switches on the back of the circuit board
which must be configured by the installer. The ON position
is indicated by small letters on the switch. Ignore the num-
bers (1-4) on the switch. The switch designation (A-D) is printed
on a sticker next to the switch. To change a switch position,
use the corner of a small screwdriver to slide the switch
ON or OFF. Set the DIP switches before installing the
thermostat.

A. Air Conditioner or Heat Pump Selection (Switch A)

Use switch A to select between air conditioning and heat pump
applications. A heat pump application uses a reversing valve.
Set switch A to OFF for air conditioning applications (no re-
versing valve). Set switch A to ON for heat pump applica-
tions (O is used to energize the reversing valve). The factory
setting is OFF.

B. Compressor Stage Selection (Switch B)

Switch B is used to select between a single-stage and a 2-stage
compressor. Set switch B to OFF for a single-stage compres-
sor. Set switch B to ON for a 2-stage compressor. The factory
setting is OFF.

C. Outdoor Air or Remote Room Sensor (Switch C)

Switch C is used to configure the thermostat to work with
either a outdoor air sensor or a remote room sensor. The sen-
sor for the application must be connected to terminals S1 and
S2 of the thermostat. Set switch C to OFF for a outdoor air
sensor. Set switch C to ON for a remote room sensor. The fac-
tory setting is OFF.

D. Averaging of Sensors (Switch D)

Switch D is used if a remote room sensor is being used (switch C
set to ON). The remote room sensor reading can be averaged
with the sensor reading of the thermostat. Set switch D to
OFF if averaging is not required. To average the readings of
the thermostat and remote room sensors, set switch D to ON.
The factory setting is OFF.

III. INSTALL THERMOSTAT

WARNING:

Before installing thermostat, turn off all

power to the unit. There may be more than one power
disconnect. Electrical shock can cause injury or death.

1. Turn off all power to unit.

2. If an existing thermostat is being replaced:

a. Remove existing thermostat from the wall.

b. Disconnect wires from existing thermostat. Do not

allow wires to fall back into the wall. As each wire
is disconnected, record wire color and terminal
connection.

c. Discard or recycle old thermostat.

NOTE:

Mercury is a hazardous waste and must be disposed

of properly.
