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. 1.
Fig. 1. 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.
Mount the thermostat horizontally on the wall:
1. Pull the wires through the wire hole on the wall-
2. Position the wallplate on the wall with the arrow
3. Use a pencil to mark the mounting holes.
4. Remove the wallplate from the wall and drill two
5. Pull the wires through the wire hole on the wall-
6. Insert the mounting scre ws into the wall anchors

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.

You can choose from three methods to power the
thermostat:
• Batteries only (A A alkaline).
• 24 Vac direct connection only.
• 24 Vac direct connection with battery backup (AA
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. 22.

SETTING 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 and time for this
thermostat:
SETTING DATE/TIME WHEN THERMOSTAT IS
FIRST POWERED
When the thermostat is first powered, the display is
ready to set the calendar and time. The thermostat
proceeds through a sequence of setup screens. See
Fig. 25.
Fig. 25. Setting calendar and time after initial powerup.
ADVANCED SETTINGS
The thermostat has advanced settings to match the
HVAC system. These settings can be adjusted to
match specific needs. See the following section
(Installer Setup Numbers, Settings, and Tests) for
details.
SETTING DATE/TIME AFTER THERMOSTAT IS
ALREADY FUNCTIONING
Use the installer setup to set year, month and day. See
the Installer Setup Numbers, Settings, and Tests
section.

OPERATION
TB7100A1000 MULTIPRO™ MULTISPEED AND MULTIPURPOSE THERMOSTAT
Fan Sequence Operations (ISU 347, 348, 349)
If heat pump or conventional application modes are
enabled in ISU 170, then ISU 347 is not available for
fan ramp algorithm. The fan operates as a default ON/
AUTO selection that works the same way as our
CommercialPRO TB7220 thermostat. There is only
one fan relay output that is activated.
If PTAC or fan coil thermostat application modes are
enabled in ISU 170, then ISU 347 is available for
installer setup selection.
The thermostat comes factory default with the fan
ramping algorithm enabled (ISU 347). This gives the
user the ability to select Auto -Lo-Med-Hi option in ISU
348 or Auto only option in ISU 348. Auto sets the
thermostat into the fan ramping algorithm mode and
automatically sets the sufficient speed for PI control.
Auto also automatically shuts the fan off when there is
not a call for heating or cooling. If the user decides to
disable ISU 347, then the fan will only have Lo-Med-Hi
option available.
If ISU 347 is not enabled, then ISU 348 does not
appear as a user selection choice.
If ISU 347 is enabled, then ISU 349 is available as a
selection choice. The user can select either a 2 hour or
4 hour timer fan reset function. The fan will reset from
a constant speed to auto mode after the time period
expires. If ISU 347 is not enabled, then ISU 349 does
not appear as a user selection choice.
Equipment Sequence Operations (ISU 170)
Heat Pump and Conventional
Heat Pump and conventional use a single fan speed.
The single fan speed label will be G, located on the G1
terminal relay output. Label should read G/Gl to help
out the installers. Display on the thermostat for these
modes will give the Fan On/Auto option. There is no
fan ramping algorithm, ISU 347, 348, 349 are not
available.
PTAC
PTAC modes 10 and 11 will have the same selection
options available as the heat pump selection options.
The only difference is that the PTAC options have a Lo
and Hi speed fan output instead of single speed
output and that it follows the fan sequencing
described above with ISU 347, 348, 349.
4 Pipe
4 pipe is treated similar to 1H/1C conventional. It
follows the fan sequencing described above with ISU
347, 348, 349.
2 Pipe
There are two different 2 pipe modes - 2 pipe only and
2 pipe with reheat.
2 pipe only
2 pipe modes do not contain the ability to have
automatic changeover. They are manual changeover
only. The thermostat will have a priority when
choosing a system mode (heat or cool). When ISU 340
has a 2 pipe changeover sensor enabled, the
thermostat screen system mode will lock on heat or
cool (whatever the changeover sensor is
communicating to the thermostat). If ISU 340 does
not have a changeover sensor enabled, then the
system mode from the thermostat screen can
manually be adjusted between heat or cool. It follows
the fan sequencing described above with ISU 347,
348, 349.
2 pipe with reheat
2 pipe modes do not contain the ability to have
automatic changeover. They are manual changeover
only. The thermostat will have a priority when
choosing a system mode (heat or cool). When ISU 340
has a 2 pipe changeover sensor enabled, the
thermostat screen system mode will lock on heat only.
When the 2 pipe changeover sensor is sensing cool
mode, the user can adjust to heating mode which will
bring on the auxiliary heat. If ISU 340 does not have a
changeover sensor enabled, then the system mode
from the thermostat screen can manually be adjusted
between heat or cool. It follows the fan sequencing
described above with ISU 347, 348, 349.
Special Programmable Mode Functions
Installer Setup 160 allows the thermostat to be
configured for either a mode with a programmable 7
day schedule or as a non-programmable thermostat.
Preoccupancy purge (ISU 185)
This feature is available only when the thermostat is
configured as a programmable schedule and when a
fan is used. The fan will run 1-3 hours before the
occupied schedule starting time to circulate air.
Override Button, Temporary Override (Duration
Limit ISU 535)
While in the programmable schedule mode, an
override button is available to perform temporary
override control. The default override time can be
configured through ISU 535. Lockout configuration
via ISU 670 can provide restrictions on access to
setpoint changes, system changes, and schedule
changes.
No remote setback
The remote setback feature only works in the nonprogrammable mode.
Special Non-Programmable Mode Functions
Override (Optional)
The override feature is optional in the nonprogrammable mode. The override can be configured
through ISU 342. When the override is activated in the
non-programmable mode it will temporarily override
to a new setpoint until the end time expires.
Remote Setback
Remote Setback is available (ISU 340). Occupancy
sensors, manual time clock inputs, and DDC night
setback can be used to provide inputs to setback the
thermostat. Unoccupied heating (ISU 343) and
unoccupied cooling (ISU 346) setpoints are available
to configure the setback setpoints.

Minimum-Off Timer (Compressor Protection)
The thermostat has an adjustable Minimum-Off Timer
that can be set from zero to five minutes (Factory
Setting—five minutes). The Minimum-Off Timer can
be bypassed through the Installer System Test or it
can be bypassed permanently by setting the
Minimum-Off Timer to 0 minutes in the Installer
Setup. The Minimum-Off Timer is activated after the
compressor turns off:
— If the thermostat is system powered (common wire),
the Minimum-Off Timer is also activated upon
initial startup and after power interruptions.
— If there is a call for cooling or heating during the
Minimum-Off Time, the thermostat displays “Wait.”
— When the Minimum Off Timer expires, “Cool On” or
“Heat On” (heat pumps only)” appears solidly in the
display and the compressor and fan turn on.
Indoor Temperature Sensor
Allow indoor temperature sensor to absorb the air for a
minimum of five minutes before taking a reading. See
the Sensor instructions for more information.
