FOR CONVENTIONAL, HEAT PUMP, FAN COIL AND PTAC SYSTEMS
APPLICATION
The TB7100A1000 MultiPRO™ Multispeed and
Multipurpose Thermostat is an effortless, seven-day
programmable or non-programmable thermostat that
provides universal system compatibility, precise comfort
control and is easy-to-program.
The TB7100 provides temperature control for gas, oil,
electric, heat pumps, PTACs, and fan coil equipment for
the following types of applications:
— 1H/1C conventional
— Up to 2H/1C heat pump
— 4 pipe fan coil (3 fan speeds)
— 2 pipe fan coil (3 fan speeds)
— 2 pipe fan coil with Auxiliary Heat (3 fan speeds)
— PTAC (Hi, Lo fan speed)

disposal of an old control.
INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a
hazardous condition.
2. Check ratings given in instructions and on the prod-
uct to ensure the product is suitable for your appli-
cation.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect power supply before installation.
Select Thermostat Location
Select a location for the thermostat about 5 ft (1.5m)
above the floor in an area with good air circulation at
average temperature. See Fig. 5.
Fig. 5. Select thermostat location.
Do not install the thermostat where it can be affected by:
— Drafts or dead spots behind doors and in corners.
— Hot or cold air from ducts.
— Radiant heat from sun or appliances.
— Concealed pipes and chimneys.
— Unheated (uncooled) areas such as an outside wall
behind the thermostat.
Separate Wallplate from
Thermostat
1. Separate the wallplate from the thermostat. See
Fig. 6.
Fig. 6. Separate wallplate from thermostat.
Install Wallplate (See Fig. 7)
Mount the thermostat horizontally on the wall:
1. Pull the wires through the wire hole on the wallplate.
2. Position the wallplate on the wall with the arrow
pointing up. Level the wallplate for appearance only.
3. Use a pencil to mark the mounting holes.
4. Remove the wallplate from the wall and drill two
3/16 in. holes in the wall (if drywall) as marked. For
firmer
material such as plaster, drill two 7/32 in. holes. Tap
the wall anchors (provided) into the drilled holes
until flush with the wall.
5. Pull the wires through the wire hole on the wallplate
and position the wallplate over the wall anchors.
6. Insert the mounting screws into the wall anchors
and tighten.

WIRING
CAUTION
Electrical Shock Hazard.
Can cause electrical shock or equipment
damage.
Disconnect power supply before connecting wiring.
IMPORTANT
— All wiring must agree with applicable codes,
ordinances and regulations.
— Use 18 gauge thermostat wire. Shielded cable is
not required.
NOTES:
— Refer to Table 5 for terminal designation
descriptions.
— See Fig. 11 through 17 for wiring diagrams for
specific equipment applications.
1. Select set of terminal identifications that correspond
to your system type (conventional or heat pump). See
Fig. 8.
Fig. 8. Terminal identifications for system type.
2. Loosen screw terminals used for the application.
3. Insert the wires into the terminal block and tighten
each screw terminal. See Fig. 9.
Fig. 9. Insert wires into terminal block.
4. Push excess wire back into the wall opening and
restrict wires to the shaded area. See Fig. 10.
5. Plug the wall opening with nonflammable insulation
to prevent drafts from affecting the thermostat.

Table 5. Terminal Designation Descriptions. NOTES:
1. When used in a single-transformer system,
leave metal jumper wire in place between Rc
and R. If used on a two-transformer system,
remove metal jumper wire between Rc and R.
2. Common wire is optional when thermostat is
used with batteries. When using separate
transformers for heating and cooling, the com-
mon must come from the cooling transformer.
3. If thermostat is configured for a heat pump in
the Installer Setup, configure changeover valve
for cool (O-factory setting) or heat (B).
4. Sensor wires must have a cable separate from
the thermostat control cable.

POWER THE THERMOSTAT
You can choose from three methods to power the
thermostat:
• Batteries only (AAA alkaline).
• 24 Vac direct connection only.
• 24 Vac direct connection with battery backup
(AAA alkaline).
Wiring 24 Vac Common
• Single-Transformer System—Connect the common side
of the transformer to the C screw terminal of the
thermostat wallplate. Leave the metal jumper wire in
place between Rc and R.
• Two-Transformer System—Connect the common side of
the cooling transformer to the C screw terminal of the
thermostat wallplate. Remove the metal jumper wire
between Rc and R.
Installing Batteries
1. Install two AA alkaline batteries on the back of the
thermostat as marked. See Fig. 23.
Fig. 23. Installing batteries.
2. Locate and remove tab labeled Remove. See Fig. 24.
IMPORTANT
This tab must be removed in order to set the real-
time clock.
Fig. 24. Remove tab labeled REMOVE from
thermostat back.
Locate and Mount TR21 or C7189U
Remote Indoor Temperature Sensor
(Optional)
Locate and mount the sensor in the same fashion as the
thermostat. See the Select Thermostat Location section.
Consider the following as well:
1. Be sure wire distance between sensor and thermo-
stat is less than 200 feet.
2. Mark the area on the wall selected for mounting the
sensor or junction box.
3. Sensor wire must be separate from the thermostat
cable.
4. Run wire cable to a hole at the selected wall location.
5. Pull approximately three inches of wire through the
opening.
NOTE: Color-coded, 18-gauge wire is
recommended.

CAUTION
Electrical Interference (Noise) Hazard.
Can cause erratic system operation.
Keep wiring at least one foot away from large
inductive loads such as motors, line starters, lighting
ballasts and large power distribution panels.
1. Check Installer Setup Number (ISU) 340 to ensure it
is set to the desired value. (See Table 6.)
2. Wire sensor to S1 and S2 thermostat terminals.
3. Push excess wire back into the hole. Plug the hole
using nonhardening caulk, putty or insulation to
prevent drafts from affecting performance.
4. Remove sensor cover.
5. Mount sensor to the wall or junction box using the
screws and anchors provided.
6. Level the sensor for appearance only. Device func-
tions correctly even when not level.
7. Install sensor cover.

SET CALENDAR AND TIME
This thermostat is designed to, under normal use,
automatically keep current time and day in memory for up
to ten years once the calendar is set. There are two ways to
set the calendar for this thermostat:
Setting Calendar Once Functioning
See steps 1 through 4, in the Advanced Settings section, to
set year, month and day.
Setting Calendar When First
Powered
When first powered, the thermostat proceeds through a
sequence of screens to set the calendar.
— When first powered, the thermostat proceeds through a
