APPLICATION

Speedy same-schedule programming—no need to

copy multiple days.

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.

Armchair programming allows you to remove the

thermostat from the wall for programming.

•

Programmable or non-programmable modes.

The TB7100 provides temperature control for gas, oil, electric,

heat pumps, PTACs, and fan coil equipment for the following

types of applications:

Remote setback input for occupancy sensors or

timeclocks.

•

VersaSpeed™ fan ramping algorithm and fan reset

algorithm (fan coil and PTAC applications).

INSTALLATION

When Installing this Product...

Read these instructions carefully. Failure to follow them

could damage the product or cause a

hazardous condition.

Check ratings given in instructions and on the product to

ensure the product is suitable for your application.

Installer must be a trained, experienced service

technician.

After installation is complete, check out product

operation as provided in these instructions.

Electrical Shock or Equipment Damage Hazard.

Can shock individuals or short equipment

circuitry.

Mount the thermostat horizontally on the wall:

Pull the wires through the wire hole on the wallplate.

Position the wallplate on the wall with the arrow pointing

up. Level the wallplate for appearance only.

Disconnect power supply before installation.

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.

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.

Pull the wires through the wire hole on the wallplate and

position the wallplate over the wall anchors.

Insert the mounting screws into the wall anchors and

tighten.

Description

Power for cooling—connect to secondary side

(

see Note 1) of cooling system transformer.

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.

If thermostat is configured for a heat pump in the

Installer Setup, configure changeover valve for

cool (O-factory setting) or heat (B).

Power for heating—connect to secondary side

(see Note 1) of heating system transformer.

Common wire from secondary side of cooling

(see Note 2) system transformer.

Sensor wires must have a cable separate from the

thermostat control cable.
