Locate and Mount C7089U Outdoor
Temperature Sensor (Optional)
Mount the sensor where (see Fig. 25):
• cannot tamper with settings.
• there is good air circulation.
• it can measure true outdoor ambient temperature.
• surface is flat.
• wire distance between C7089 and thermostat 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.

CAUTION

Use the following steps to mount the sensor:
1. Remove the sensor from the mounting clip.

Wire C7189 Indoor Sensor

Choose a location (see Fig. 27) for mounting the sensor
on an inside wall about 5 ft (1.5m) above the floor. A
vertically-mounted standard 2 x 4 in. (51 x 102 mm)
junction box can also be used.
Be sure wire distance between C7189 and thermostat is
less than 200 feet.
Make sure there is good air circulation at average
temperature at the chosen location. Avoid the following
locations because they can introduce errors in sensor
measurements. See Fig. 27.
a. Hot areas caused by:
(a) Concealed pipes or ducts.
(b) Drafts from fireplaces or other heat sources.
(c) Convection or radiant heat from the sun or
electrical equipment.
b. Cold areas caused by:
(a) Concealed pipes or ducts.
(b) Drafts from windows and doors.
(c) Unheated areas on the other side of the wall
location.
c. Dead air areas:
(a) Behind doors, furniture and curtains.
(b) In corners and alcoves.
Mark the area on the wall selected for mounting the
C7189 Sensor or junction box.
Run wire cable to a hole at the selected wall location.
Pull approximately three inches of wire through the
opening. Color-coded, 18-gauge thermostat wire is
recommended.

CAUTION

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.
— 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.

CAUTION

heating or cooling at just the right time to have the home
reach the scheduled temperature at the scheduled time.
For example—get up at 6:00 AM and want the temperature to
be 70°F. Set the Wake period for 6:00 AM and 70°F. The
thermostat then turns on the heat before 6:00 AM to raise the
temperature to 70°F by 6:00 AM.

The thermostat alerts that the heating or cooling system is

NOTE: It takes about a week for the thermostat to adjust to

accordingly.

P+I Control
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 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 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 additon of the integral error is what differentiates the
thermostat from many other electronic and mechanical
thermostats. See Fig. 31.

The C7089 Outdoor Sensor converts outdoor ambient
temperature to a resistance that the thermostat can interpret.
The C7089 has a negative temperature coefficient (TC), which
means that resistance decreases as the temperature
increases. See Table 12.

Checkout
Allow C7089U 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
C7089 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 C7089 Outdoor Sensor is calibrated at the factory and
cannot be recalibrated in the field.
