Locate and Mount C7089U1006 Outdoor
Temperature Sensor (Optional)
Mount the sensor where (see Fig. 23):
• cannot tamper with settings.
• there is good air circulation.
• it can measure true outdoor ambient temperature.
• surface is flat.
• wire distance between C7089U1006 and EIM is less than
200 feet.
IMPORTANT
Erratic temperature readings from a sensor can occur
as a result of any of the wiring practices described
below. Avoid these practices to assure correct operation. Use shielded cable to reduce interference if
rerouting sensor wiring is not possible.
— Be sure wires have a cable separate from the thermostat cable.
— Do not route temperature sensor wiring with building
power wiring, next to control contactors or near light
dimming circuits, electric motors or welding
equipment.
— Avoid poor wiring connections.
— Avoid intermittent or missing building earth ground.
Do not mount the sensor:
• in direct sunlight.
• where hot or cold air blows on the sensor. Discharge line
from an outdoor compressor unit, vent or fan causes
inaccurate temperature readings.
• where snow, ice or debris can cover it.
Use the following steps to mount the sensor:
1. Remove the sensor from the mounting clip.
2. Mark the area on the location selected for mounting the
sensor mounting clip.
3. Mount the clip.

• The thermostat will display the temperature measured at
the sensor locations (internal thermostat sensor is
disabled). Sensors must be in square numbers (e.g., 4, 9,
16, and so on) and the displayed temperature will be an
average of the temperatures measured at each location.
• The thermostat will display a 50-50 average of the
temperature measured at the thermostat location and the
average of the temperatures measured at the remote indoor
sensor locations. In this case, the thermostat sensor still
carries a 50% weighting of the displayed temperature.

If a remote indoor temperature sensor is installed, the
thermostat has several options for displaying the current indoor
temperature. This is configured in ISU 340. The thermostat can
display either the temperature measured at the thermostat
location, the sensor location, or a 50-50 average of both.

Using Auto Discover
Some Installer setups are defaulted to Auto Discover. If not
defaulted, the installer can change the option to Auto Discover,
however, it is always important that the installer verify that the
auto discovered values are correct for the system that is
present.
When using the thermostat with an equipment interface
module, Auto Discover will discover factory default settings
and will not receive communications as to proper system
settings. The equipment interface module is preprogrammed at
the factory as a one heat one cool product and the thermostat
will “auto discover” those settings. The equipment interface
module will be reprogrammed when the installer manually
changes the configuration in the installer set up. It is not
recommended to use Auto Discover with an equipment
interface module.

When using the VisionPRO® IAQ thermostat with a W8835
zone panel, configure the zone panel, using the DIP switches
on the panel, for the proper system settings. Enter the installer
setup on each thermostat and assign zone numbers, and
change the system settings (ISU 172–180) to Auto Discover
(E) then press the discover button on the zone panel. The zone
panel will then communicate those settings back to the
thermostats and the thermostats will automatically configure
the ISU settings in Auto Discover, again it is important to verify
that the auto discovered values are correct.

NOTE: When a VisionPRO® IAQ thermostat is being added
to an existing zoning system with T8635 Thermostats
the new VisionPRO® IAQ must be set up as the Zone

Control Humidification Level
The VisionPRO® IAQ Touchscreen Thermostat reads the
inside humidity level and allows for a humidification setting with
or without frost protection. Humidification will only take place
when the thermostat is in Heat mode or in Auto mode when the
previous call was a call for heating.
WITH FROST PROTECTION
Controlling humidification with frost protection requires an
outdoor temperature sensor. The Frost Index (scale 1–10) will
limit the amount of humidity added to the air based on outdoor
temperature, with 1=most dry and 10=most humid. This
prevents frost from accumulating on windows.

VISIONPRO® IAQ TOTAL HOME COMFORT SYSTEM
DEHUMIDIFICATION DROOP CONTROL
In extremely high humidity conditions, the thermostat keeps
the air conditioner running (energizing Y/Y2 and G) for up to
3°F below the temperature setpoint. It does this while trying to
achieve the desired humidity setpoint and balancing that with
the temperature setpoint. The thermostat controls up to 3° F
below the temperature setting until either the humidity setpoint
is satisfied or conditions change.
With Whole House Dehumidifier
Controls humidity levels in the house by dehumidifying without
the use of the air conditioner. This setting requires a dedicated
unit for dehumidification. Dehumidification with a whole house
dehumidifier will take place when the thermostat is in the Cool,
Off, Auto, Heat or Em.Heat modes. If the system is installed
with a whole house humidifier, dehumidification with a whole
house dehumidifier will only take place when the thermostat is
in Cool, Off or Auto modes (Auto only if the previous call was a
call for cooling).
When controlling a whole-house dehumidifier the user can
toggle between auto (dehumidify when needed based on
setpoint and current humidity level) and off (see Fig. 29).

Ventilation occurs two ways:
AUTOMATIC
Uses installer setup to determine amount of ventilation
required based on house and equipment size. To disable
automatic ventilation, switch the ventilation setting to Off. The
user can still use the timer to request ventilation.
ON DEMAND
User can also set a vent timer that will circulate fresh air into
the home for a set period of time from 20 to 180 minutes in 20minute increments. The vent timer is enabled whether

Ventilation Control
Ventilation setup options include ISUs 400, 401, 402, 403, and
404. Combined, these will determine a percentage of
maximum ventilation limit. The thermostat will calculate
whether or not this level of ventilation meets ASHRAE
standard 62.2. If ASHRAE 62.2 is met a P will appear in the
display above the setup number. If ASHRAE 62.2 is not met an
F will appear in the display above the setup number.
Passing ASHRAE 62.2 is only applicable when vent is running.
For example, if installer has set to not vent during sleep period,
ASHRAE 62.2 would be met at all times except during sleep
period.

Multi-Stage Heat and Cool Control
In a multi-stage system, while maintaining setpoint, several
factors affect when the next stage energizes, such as load
conditions, environmental conditions, P+I control, and home
insulation. The next stage energizes when the thermostat
senses the previous stage is running at 90% capacity. This
operation is droopless control.

Minimum Off-Timer
P+I Control
If there is a call during the minimum-off timer, the thermostat
shows “Wait” in the display.
The thermostat microprocessor-based control requires that the
user understands temperature control and thermostat
performance. 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. This is a phenomenon that most people
in the industry know and accept. Many factors contribute to
offset including switch differential, thermal lag, overshoot, cycle
rates and system load.
The Thermostat has built-in compressor protection (minimumoff timer) that prevents the compressor from restarting too
early after a shutdown. The minimum-off timer is activated after
the compressor turns off.
WED
FAN
The thermostat also determines integral error, which is a
deviation based on the length of error time. 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.
The addition of the integral error is what differentiates the
thermostat from many other electronic and mechanical
thermostats. See Fig. 33.
Set To
Wait
Following
Schedule
SYSTEM
The thermostat microprocessor simultaneously gathers,
compares and computes data. Using this data, it controls a
wide variety of functions. The special proprietary algorithm
(program) in the thermostat eliminates the factors causing
offset. This makes temperature control more accurate than the
conventional mechanical or electronic thermostats. The
temperature control algorithm is called proportional plus
integral (P+I) control.
The thermostat sensor, located on the thermostat or remote,
senses the current space temperature. The proportional error
is calculated by comparing the sensed temperature to the
programmed setpoint. The deviation from the setpoint is the
proportional error.

The C7089U1006 Outdoor Sensor converts outdoor ambient
temperature to a resistance that the thermostat can interpret.
The C7089U1006 has a negative temperature coefficient
(NTC), which means that resistance decreases as the
temperature increases. See Table 12.
Checkout
Allow C7089U1006 Outdoor Sensor to absorb outdoor air for a
minimum of twenty minutes before taking a reading.
With an accurate thermometer (±1°F [0.5°C]) measure the
temperature at the sensor location, allowing time for the
thermometer to stabilize before reading.
To verify sensor resistance, remove one wire from one of the
C7089U1006 60-in. leadwires. Use an ohmmeter to measure
the resistance across the sensor. Then verify the sensor
accuracy with the temperature/resistance in Table 12.
Calibration
The C7089U1006 Outdoor Sensor is calibrated at the factory
and cannot be recalibrated in the field.

C7189U1005 Remote Indoor Temperature
Sensor
Operation
When installed with Thermostat Installer Setup Number 0340
set to 1, the remote inside temperature is displayed on the
thermostat home screen as Inside Temperature. The
thermostat internal temperature sensor is not used. When
68-0287—1
VISIONPRO® IAQ TOTAL HOME COMFORT SYSTEM
installed with Thermostat Installer Setup Number 340 set to 2,
the temperature displayed on the thermostat home screen as
Inside Temperature will be a 50/50 average between the
temperature sensed at the remote sensor location and the
temperature sensed at the thermostat location.
The C7189U1005 Wall Mount Temperature Sensor converts
room temperature to a resistance that the thermostat can
interpret.
The C7189U1005 has a negative temperature coefficient
(NTC), which means that resistance decreases as the
temperature increases. See Table 13.
The C7189U1005 can be used to provide one remote sensor
input (see Fig. 26) or as a temperature averaging network with
multiple C7189U1005 Sensors connected, as shown in Fig. 27.
Checkout
For best results, allow C7189U1005 Wall Mount Temperature
Sensor to absorb the air moving through the room for a
minimum of twenty minutes before taking a resistance
measurement.
COMMUNICATION ERROR CODES
VisionPRO® IAQ can alert the homeowner and installer to
problems with the HVAC equipment, thermostat, or equipment
interface module by using error codes. Please see Table 14 for
a list of error codes. When an error is active (the condition
causing the error is still present) it will be displayed in the time
field on the thermostat home screen. The home screen can
display up to 5 active errors. The time field will flash the time,
“Err,” and a list of up to 5 error codes, beginning with the most
critical, and repeat until the errors have been remedied.
A log of error codes can be viewed at the end of the installer
setup after the system tests. Active errors will be shown first.
The Error Log will log the last ten errors (active and inactive).
Pressing the reset button will clear all inactive errors from the
error log; active errors can not be cleared until the condition
has been remedied.
Table 14. VisionPRO® IAQ Error Codes.
Error Code
Meaning
With an accurate thermometer (±1°F [0.5°C]) measure the
temperature at the sensor location, allowing time for the
thermometer to stabilize before reading.
