NOTES:

1. When used in a single-transformer system, leave

metal jumper wire in place between Rc and R. If

used on a two-transformer system, remove metal

jumper wire between Rc and R.

2. Common wire is optional when thermostat is used

with batteries.

3. If thermostat is configured for a heat pump system

in the Installer Setup, configure changeover valve

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

4. L terminal is an input (system monitor) when the

System mode is in the Heat, Off, Cool or Auto

position. L terminal is a 24 Vac output when

System mode is Emergency Heat. Must connect

the 24 Vac Common when using the L terminal.

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.

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.

Fig. 25. Typical locations for C7089U Outdoor Sensor.

Wire C7089U Outdoor Sensor

CAUTION

Electrical Interference (Noise) Hazard.

Can cause erratic system operation.

Keep wiring at least one foot away from large inductive

loads such as motors, line starters, lighting ballasts

and large power distribution panels.

Use shielded cable to reduce interference when

rerouting is not possible.

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.

CAUTION

Electrical Shock Hazard.

Can cause electrical shock or equipment damage.

Disconnect power supply before connecting wiring.

Wiring must comply with applicable codes, ordinances and

regulations:

1. Wire C7089 Outdoor Sensor to S1and S2 terminals on

the thermostat. If leadwire provided is not long enough

(60 in.), run a cable to a hole at C7089 location.

a. Using color-coded, 18-gauge thermostat wire is

recommended. For example of general wiring of

C7089, see Fig. 26.

b. Pigtail wiring can be used.

2. Mount C7089 in its mounting clip.

3. Plug wiring hole using nonhardening caulk or putty.

Temperature Recovery

The thermostat feature, Adaptive Intelligent Recovery™,

eliminates all guesswork when setting the thermostat

schedule.

Simply set the program schedule to the time that the comfort

temperature is desired. The thermostat then turns on the

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

coming on before a scheduled time by showing “Recovery” on

the screen.

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

local weather, the schedule, the construction of the

home and the heating and/or cooling system. Each

day it adjusts the next day’s recovery start time

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.

Minimum Off-Timer

The Thermostat has built-in compressor protection (minimum-

early after a shutdown.

The minimum-off timer is activated after the compressor turns

off.

If there is a call during the minimum-off timer, the thermostat

shows “Wait” in the display.

When the minimum-off timer expires, “Cool On” or “Heat On”a

appears solidly in the display and the compressor and fan turn

Control Dehumidification Setting (Select Models)

Select models read the inside humidity level and allow for a

dehumidification setting:

1. Press the More key until the inside humidity percent and

dehumidification setpoint are shown.

2. Use Up and Down arrow keys, located to the right of the

dehumidifier setpoint, to set desired humidity level for

dehumidification in the summer.

3. Press Done key.

Dehumidification Droop Control

The dehumidification control attempts to control to the user's

humidity setpoint by turning on the air conditioner. In

extremely high humidity conditions, the thermostat keeps the

air conditioner running (energizing Y 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 is

satisfied or conditions change.

Special Heat Pump Operation

Heat Pump LED Indication (Requires 24 Vac

Common Connection)

A red LED indication is located in the upper right corner of the

thermostat. It is only visible when lighted.

When the L terminal is wired to an equipment monitor, the

LED signals when a check or fail signal is sent to the

thermostat from the system. This is operational in the Heat,

Off, Cool or Auto positions. See Fig. 32.

Fig. 32. L terminal switch to R (power) side of system

transformer.

Heat Pump Emergency Heat LED Indication

(Requires 24 Vac Common Connection)

The thermostat uses a red LED indicator that lights when the

thermostat is in the Emergency Heat mode. The LED is

located in the upper right corner of the thermostat. It is visible

only when on. When the thermostat is in the Em. Heat system

mode, the L terminal is continuously energized and the LED is

C7089U Outdoor Temperature Sensor

Operation

When installed with Thermostat Installer Setup Number 0340

set to 1 or 2, the outside temperature can be displayed on the

thermostat. See Fig. 35.

Fig. 35. Outside temperature reading on

TH8000 Series Thermostat.

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.

C7189U Remote Indoor Temperature Sensor

Operation

When installed with Thermostat Installer Setup Number 0340

set to 3, the remote inside temperature is displayed on the

Thermostat Home Screen as Inside Temperature. The

thermostat internal temperature sensor is not used. See Fig.

36.

Fig. 36. Inside temperature reading on

TH8000 Series Thermostat.

The C7189 Wall Mount Temperature Sensor converts room

temperature to a resistance that the thermostat can interpret.

The C7189 has a negative temperature coefficient (NTC),

which means that resistance decreases as the temperature

increases. See Table 13.

The C7189 can be used to provide one remote sensor input

(see Fig. 28) or as a temperature averaging network with

multiple C7189 Sensors connected, as shown in Fig. 29.

Checkout

For best results, allow C7189 Wall Mount Temperature Sensor

to absorb the air moving through the room for a minimum of

twenty minutes before taking a resistance measurement.

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

C7189 wiring terminals. Use an ohmmeter to measure the

resistance across the sensor. Then verify the sensor accuracy

with the temperature/resistance in Table 13.

Calibration

The C7189 Wall Mount Temperature Sensor is calibrated at

the factory and cannot be recalibrated in the field.
