APPLICATION
The TB7100A1000 MultiPRO™ Multispeed and Multipurpose
Thermostat is an effortless, seven-day programmable or nonprogrammable 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)
program schedule, as desired.
• Speedy same-schedule programming—no need to
copy multiple days.
• Armchair programming allows you to remove the
thermostat from the wall for programming.
• Programmable or non-programmable modes.
• Remote setback input for occupancy sensors or
timeclocks.
• VersaSpeed™ fan ramping algorithm and fan reset
algorithm (fan coil and PTAC applications).
• Up to 3 fan speeds for fan coil and 2 speeds for PTAC
applications.
• Remote indoor air sensing option (20K ohm or 10K
ohm).

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

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.

Conventional System Wiring
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 common 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.
