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.

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.

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.

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.

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.

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 on.
