APPLICATION
The VisionPRO® 8000 Smart thermostat features an
effortless, 7-Day programmable touchscreen thermostat
that provides control of temperature and one of the
following: humidification, dehumidification, or ventilation.
Up to 3 Heat/2 Cool heat pump systems or up to
2 Heat/2 Cool conventional systems are supported in
residential and commercial applications.
Set up to 10 service reminders. Choose from the pre-set
options or customize your own. Reminders can be
based on date or the outdoor temperature.
• Selectable for Residential and Light Commercial
Applications
One thermostat does it all to meet the needs of Residential and Light Commercial applications. Simply
select Residential or Commercial during the installer
setup. If Commercial is selected, the thermostat will use
commercial language, meet building codes and offer
365 day holiday scheduling.
The thermostat keeps the indoor temperature
within 1 degree of the setpoint (droop less control). The
thermostat turns on stage 2 when the capacity on stage
1 reaches 90%.
When the interstage differential is set to 1.0 or higher, the
thermostat stages the equipment based on how far the
indoor temperature is from the setpoint (ISU 303 to
309). See page 16 for more information.
Clock Accuracy: 1 minute per month at 77 °F (25 °C). ± 2
minutes per month over the operating ambient temperature range.
Mounting Means:
Thermostat mounts directly on the wall in the living space
using mounting screws and anchors provided. Fits a
horizontal 2 x 4 in. junction box.
Power Consumption of TH8321:
Backlight on: 1.48 VA
Backlight off: 0.88 VA
Temperature Setting Range:
Heating: 40 to 90 °F (4.5 to 32 °C).

Deadband is the minimum separation between heat
and cool settings when the thermostat is setup for
Auto Changeover. For example, if the deadband is set
to 3° F and the cool setpoint is 75° F, the warmest
heat setpoint allowed would be 72° F. If the heat
setpoint is adjusted above 72° F, it will automatically
adjust the cooling setpoint higher to maintain the 3°
F deadband.
When ISU 907 or ISU 910 (Dehum Over Cooling
Limit) is set to 1, 2, 3, 4 or 5 F, the thermostat will
not show the full Deadband range. For example, if
you set a Deadband of 3 F and an Over Cooling Limit
of 2 F, the minimum Deadband that you can select
will be 5 F. This prevents the heating system from
turning on when the thermostat over cools to reach
the dehumidification setting.

ASHRAE
Residential ,

or BothNotes
LockoutsResidentialLockouts are Priority: The thermostat places a
priority on lockouts versus the ASHRAE 62.2
ventilation standard. The thermostat will not run
ventilation during the following lockout conditions
(if configured) unless you manually call for
ventilation:
•
Lockout Ventilation during Outdoor Conditions
(ISU 1013)
• Lockout Ventilation on Humidification or
Dehumidification Calls (ISU 1014)
• Lockout Ventilation during “Sleep” (Residential)
or “Unoccupied” (Commercial) program periods.
Note: This option is set by the user on the
Ventilation screen in the Menu.
ASHRAE is Priority: ASHRAE requires additional
ventilation following a long off cycle. The thermostat
meets the ASHRAE 62.2 ventilation standard by
running additional ventilation when outdoor
conditions are favorable. If ASHRAE cannot be met
when outdoor conditions are favorable, the
thermostat will override the outdoor lockouts and
run ventilation. When using this option, it is
recommended to increase the rate (CFM) of the
ventilation equipment to meet the ASHRAE 62.2
ventilation standard in a shorter run time.

Advanced Features
ADAPTIVE INTELLIGENT RECOVERY (RESIDENTIAL
USE ONLY)
Over time, the VisionPRO® thermostat "learns" how long it
takes your system to reach your programmed temperature
setting.
The thermostat turns on the heating/cooling system early
and assures that the programmed temperature setting is
reached at the programmed time regardless of weather
conditions. For example, if the Wake program period is set
to 6:00 am with a heat setting of 70 degrees, the heat will
turn on before 6:00 am, so the temperature is 70 degrees at
6:00 am. The thermostat displays "In Recovery" when it
turns the system on early.
Adaptive Intelligent Recovery® calculates the recovery
ramp based on how far the room temperature is away from
the temperature setting, previous equipment performance
and weather history, allowing the thermostat to start
recovery at the optimal time so it can reach the
programmed temperature setting at the programmed time.
The VisionPRO® thermostat uses two recovery ramps when
setup to control a heat pump system. One ramp for the
compressor and one ramp for the auxiliary heat. Once the
room temperature intersects the compressor ramp, the
compressor turns on until the setpoint is reached. If the
room temperature does not rise quickly enough and
intersects the second ramp, the auxiliary heat turns on. It
takes about one week for the thermostat to adjust to
weather conditions, equipment performance and
construction of the home. If the temperature setting is
reached too early or too late, the ramp is adjusted for the
next day's recovery. See Fig. 96.
P + I CONTROL
A conventional mechanical or electronic thermostat does
not control temperature precisely at setpoint. Typically
there is an offset (droop) in the control point as the system
load changes. Many factors contribute to offset including
the switch differential, thermal lag, overshoot, cycle rates
and system load.
The VisionPRO® thermostat however, works much
differently than a conventional mechanical or electronic
thermostat. The proprietary algorithm in the thermostat
eliminates the factors causing offset (droop). This makes
temperature control more accurate than the conventional
mechanical or electronic thermostat. The temperature
control algorithm is called proportional plus integral (P + I)
control.
The thermostat sensor or indoor sensor senses the current
space temperature. The proportional error is calculated by
comparing the sensed temperature to the setpoint
temperature. The deviation from the setpoint is the
proportional error.
The thermostat also determines integral error, which is a
deviation based on the length of error time (how long the
sensed room temperature has been away from the setpoint
temperature). The sum of the two errors is the (P + I) error.
The cycle rate used to reach and maintain the setpoint
temperature is computed using the P + I control algorithm.
The addition of the integral error is what differentiates the
thermostat from many other mechanical and electronic
thermostats. See Fig. 97.

Differential Between All Stages
The thermostat provides Differential settings between all
stages. The equipment changes stages based on how far
the indoor temperature is from the setpoint. Differential
settings provide a way to balance comfort and
conservation.

U1 Contacts
The U1 contacts can be setup to control IAQ equipment or
a stage of heating or cooling in the Installer Setup. Setup
options are listed below.
33-00096—0552
Heat Differential
The indoor temperature must drop to the selected
differential setting before the thermostat will turn on the
stage of heating. For example, if stage 2 is set to 2 °F
(1.0 °C), the indoor temperature must be 2 °F (1.0 °C) away
from the setpoint before stage 2 turns on. When set to
Comfort, the thermostat will use the stage of heating as
needed to keep the indoor temperature within 1 °F (0.5 °C)
degree of the setpoint. The thermostat turns on stage 2
when the capacity on stage 1 reaches 90%.
Cool Differential
The indoor temperature must rise to the selected
differential setting before the thermostat turns on the
stage of cooling. For example, if stage 2 is set to 2 °F
(1.0 °C), the indoor temperature must be 2 °F (1.0 °C) away
from the setpoint before stage 2 turns on. When set to
Comfort, the thermostat uses the stage of cooling as
needed to keep the indoor temperature within 1 °F (0.5 °C)
degree of the setpoint. The thermostat turns on stage 2
when the capacity on stage 1 reaches 90%.

• Heat Pumps with any type of Backup Heat
• Radiant Heat with any type of Backup Heat
• Hot Water Fan Coil with any type of Backup Heat
The Backup Heat Droop restricts backup heat during the
following conditions:
•Normal Operation
• Manual Setpoint Changes
When the Backup Heat Droop is set to 2 °F or higher,
backup heat is not used unless the indoor temperature
drops to the Backup Heat Droop setting or the Backup Heat
Upstage Timer expires, whichever occurs first. The upstage
timer starts when the highest stage of the previous
equipment type turns on.
MANUAL TEMPERATURE CHANGE
When the Backup Heat Droop is set to Comfort, the
thermostat uses backup heat as needed to keep the indoor
temperature within 1 °F (0.5 °C) of the setpoint. The
Comfort setting is NOT an option on heat pumps with fossil
fuel backup heat.
When the Backup Heat Droop is set to 2 °F or higher, if the
primary heat is making progress as expected, backup heat
will not be used to reach the new setpoint. Set to a higher
number to use less backup heat (a greater difference
between the current indoor temperature and the new
setpoint is required to turn on backup heat). See notes
below.
PROGRAMMED RECOVERY
If the primary heat is making progress as expected, backup
heat will not be used to reach the setpoint of the next
program period. Backup heat is always restricted during a
programmed recovery when the Adaptive Intelligent
Recovery feature is used. See note below.
NOTE: During a programmed recovery (or when the tem-
perature setpoint is changed by the user), the
thermostat waits to turn on the backup heat
depending on system performance, load conditions and how many degrees the temperature setpoint is changed. Backup heat will be used ONLY
when the temperature is not rising quickly enough
to reach the setpoint in a reasonable time.
NOTE: If the backup heat was used in the last 2 hours
because the primary heat was not able to maintain
the setpoint, the thermostat may turn on the
backup heat earlier when the user raises the setpoint. This does NOT apply to heat pumps with
fossil fuel backup heat.
TO CHANGE BACKUP HEAT DROOP SETTINGS
1. Select Basic Options or Advanced Options to
view/adjust Backup Heat Droop settings.
The options are:
• Comfort – keeps temperature within 1 degree of the
setpoint.
• 2 to 15 °F – Backup heat is not used unless the indoor
temperature drops to the selected Backup Heat Droop.
For example, if the Backup Heat Droop is set to 2 °F
(1.0 °C), the indoor temperature must be 2 °F (1.0 °C)
away from the setpoint before the backup heat turns on.
NORMAL OPERATION
When the Backup Heat Droop is set to Comfort, the
thermostat uses backup heat as needed to keep the indoor
temperature within 1 °F (0.5 °C) of the setpoint. The
Comfort setting is NOT an option on heat pumps with fossil
fuel backup heat.

Humidification
The thermostat reads the indoor humidity level and allows
the user to set a humidification setting with or without
window protection.
The thermostat can be set up to control a humidifier in any
system mode in the Installer Setup (ISU 806). A discharge
air sensor is required to humidify in the cool mode.
If humidification and dehumidification are setup to operate
in the same system mode (Heat, Cool, Off) the thermostat
will automatically enforce a 15% deadband between the
humidification and dehumidification settings. The
thermostat will automatically switch between
humidification and dehumidification to maintain the
desired humidity level.
Window Protection
Window Protection limits the amount of humidity to
prevent frost or condensation on windows. Window
Protection (ISU 805) requires an outdoor sensor.
your windows during cold outdoor temperatures, poorly
insulated windows require a lower Window Protection
setting, which will limit how much your humidifier can run.
After you set the Window Protection setting, check for
frost/condensation on your windows in the morning. If
frost/condensation is present, adjust the Window
Protection setting to the next lowest number and check for
frost/condensation on your windows the next morning.
Continue to adjust the Window Protection setting to a lower
number until frost/condensation is no longer present.

If Window Protection is turned Off, the thermostat controls
the humidity level to the user's desired humidity setting.
Frost or condensation may appear on windows.
Set up Humidification
1. Select the Humidifier Type at ISU 800. See Fig. 115.
NOTE: Based on the humidifier type you select, the
thermostat defaults to the most commonly
used settings for that humidifier type.
For example, a Bypass or Fan Powered
humidifier will default ISU 807 to “Hum
when Heat is On.”
A Steam humidifier will default ISU 807 to
"Tstat Controls Fan."
The thermostat prevents frost or condensation on windows
by not allowing the humidifier to run above a certain level.
To prevent frost or condensation, the thermostat may turn
off the humidifier before the humidity setting is reached.
To adjust the Window Protection setting, press MENU,
scroll down and select Window Protection. Window
Protection is set on a scale from 1-10. A setting of "1"

• A/C with Low Fan
• A/C with High Fan
• Hot Gas Bypass
• Dehumidifier
NOTE: Hot Gas Bypass - During a call for dehumidifica-
tion, the cooling capacity will be used to remove
more latent heat than sensible heat. The operation
of Hot Gas Bypass varies by equipment. For more
details, contact the equipment manufacturer.
Dehumidification using the Cooling
System
Dehumidification using A/C with Low Speed Fan, A/C with
High Speed Fan or Hot Gas Bypass, has the following
methods of dehumidification control (ISU 908):
heating coil (heat exchanger). This feature requires a
conventional forced air heating system (gas, oil, or electric)
in the application.
NOTE: Reheat can be used on heat pump applications
that have a forced air backup heat source (gas, oil,
or electric). The thermostat will turn on the first
stage of forced air backup heat during Reheat.
NOTE: Reheat can be used on systems where the A-Coil is
located after the heating coil (heat exchanger), but
it is not effective at removing humidity.
Reheat with Minimum On Time (ISU 908 and 909): This
method uses both Reheat and Minimum On Time options
above to reach the desired humidity level.
If set for A/C with Low Speed Fan, configure U1 as normally
open or normally closed (ISU 905) and wire to the Low
Speed Fan terminal on the equipment. For example, if the
U1 terminal is normally closed, it will open when the
thermostat calls for dehumidification.
NOTE: The thermostat will not lower the fan speed when
the second stage of cooling is on.

Basic (ISU 908): This option uses the cooling system to
reach the desired humidity level. Minimum On Time,
Cooling Droop and Reheat are not used with this method.
This setting is commonly used if your dehumidification
equipment is Hot Gas Bypass.
Minimum On Time (ISU 908 and 909): This option ensures
that the compressor runs long enough to effectively reduce
humidity when the cooling equipment is cycled on. The
compressor will run for the minimum “on time” you set until
the desired humidity level is reached.
Cooling Droop (ISU 908 and 910): This option uses the
cooling system to lower the temperature up to 5° F below
the current cool setpoint until the desired humidity is
reached. The Dehum Over Cooling Limit range is from 1° to
5° F.
Cooling Droop with Minimum On Time (ISU 908, 909, and
910): This method uses both options above to reduce
humidity while maintaining a comfortable temperature.
Reheat (ISU 908): This option allows heating to run during
dehumidification to help maintain a comfortable
temperature. If only cooling stage 1 is used, during the “off”
cycle, both cooling and heating run at the same time as
needed to dehumidify without overcooling. This option
cannot be used in the Heat mode. This option is effective

ventilation standard by running additional ventilation
when outdoor conditions are favorable. If ASHRAE
cannot be met when outdoor conditions are favorable,
the thermostat will override the outdoor lockouts and
run ventilation. When using this option, it is
recommended to increase the rate (CFM) of the
ventilation equipment to meet the ASHRAE 62.2
ventilation standard in a shorter run time.

will ventilate during calls for heat, cool, and fan. If the
required ventilation has not been achieved for ASHRAE or
Percent On Time, the thermostat will force the ventilation
equipment on.
•ASHRAE
The thermostat operates ventilation equipment to meet
the ASHRAE 62.2 ventilation standard based on CFM,
number of bedrooms, and square footage of the house.
ASHRAE 62.2 can only be met if the ventilation
equipment is running. If the ventilation equipment is off
for any reason (outdoor ventilation lockouts, set up to
The ability to lockout ventilation during the “Sleep”

when you select ASHRAE is Priority.
Ventilation will not operate when outdoor conditions
exceed the lockout settings unless you manually call for
ventilation or Ventilation Priority (ISU 1012) is set to
ASHRAE is Priority and ventilation is needed to meet
ASHRAE. Lockouts can prevent ventilation during extreme
weather conditions to keep humid, hot, and cold air out of
the home.

Ramp Rates (Commercial Use)
When the ramp rate is set to Off, the thermostat begins
recovery at the scheduled time.
When a ramp rate is set, recovery begins early to reach the
setpoint by the program time. Based on your recovery ramp
setting and how far the thermostat is set back, the
thermostat determines how early to turn on the system.
If an outdoor sensor is installed, you can set outdoor
temperatures for mild, cold and hot days in your region. By
setting these outdoor temperatures, the thermostat will
automatically adjust the ramp rate based on outdoor
conditions. This allows the thermostat to save energy by
starting recovery at the optimum time as outdoor
conditions change.
NOTE: The thermostat uses an adjustable ramp rate
when the thermostat is setup for commercial. This
allows the thermostat to recover on time during
changing conditions (occupancy changes, temperature overrides, load conditions, opening/closing of doors etc) which are common in commercial
applications.
Fig. 216.
Fig. 217.
Economizer and Time of Day (TOD)
Operation
Economizer
The thermostat controls an economizer module to provide
ventilation during occupied periods and free cooling when
outdoor conditions are favorable. In some climates the
cooling system may run several hours when it may not be
required to maintain indoor comfort. When outdoor
conditions are favorable, ventilation with outdoor air can
achieve the same level of comfort at lower cost. Table 5
explains how the Economizer Module is controlled by the
thermostat.
The thermostat works with the W7220, W7212, W7213 and
W7214 Economizer Modules for both heat pump and
conventional systems.

Pre-Occupancy Purge
The thermostat can be set up for Pre-Occupancy Purge in
the installer setup (ISU 401). When setup for PreOccupancy Purge, the thermostat runs the fan 1 to 3 hours
before each occupied period to provide a comfortable
workplace upon arrival. Options are Off and 1 to 3 hours.
In Fig. 220, both the thermostat internal sensor and wired
indoor sensor are being used for Temperature Control and
are being averaged since both sensors are set to “Yes.”

The THP9045A1098 C-wire adapter is used on heat/cool systems when you only have four wires at the thermostat and
you would like the thermostat to be powered with a common wire. Use the K terminal in place of the Y and G terminals on
conventional or heat pump systems to provide control of the fan and the compressor through a single wire—the unused
wire then becomes your common wire. See page 85 and the THP9045 instructions (form 33-00342) for more information.

Wiring with the THP9045 C-Wire Adapter
The THP9045 C-wire adapter is designed to be used with applicable thermostats in which a 24V common is required and
there are not enough wires. The K terminal on the thermostat can be used to operate both the fan and compressor on a
single wire, and the module is designed to receive the signal from the K terminal, split that signal and re-route it to operate
the compressor and/or fan for normal operation. See form 33-00342 for additional information.
