Featuring

Prepare for installation by

using the mounting holes

configured for US or

European junction boxes.

3 .

4 .

Mount the

Controller on the

base by aligning

the top clips and

then securing to

the bottom clips. A

“snap” sound will

indicate that the

sensor is secure.

The sensor will

now have power.

In less than 2 minutes, the

sensor will stabilize and display

the “Normal Mode” (current

CO2 readings).

At this point one of nine

preset programs or one

custom channel can be

selected for operation. Use

the charts below to select a

preset or to select/modify

sensor settings.

5 .

Finish installation by

sliding the cover over

the menu keys and

secure with the

supplied screw.

1 . 2 .

Secure the Mounting Plate to

the wall or junction box and

make necessary wire

connections.

Installation

Use the mounting plate

as a template to mark

mounting and wiring

holes.

6 .

Ready for

operation!

Altitude Correction and TEMA (On/Off)

1. Press + and hold (at least 5 seconds) until the sensor enters the

edit mode.

2. The first menu will be the Altitude correction. The adjustments will in-

crease/decrease in 500 ft. increments. To do this use the Up/Down Rocker

Button to adjust to the proper altitude.

3. Press to lock in value then press to proceed to TEMA.

4. Use the Up/Down Rocker Button to switch to On or Off.

5. Press to lock in value then press to proceed to Normal Mode.

Note: It is recommended that the TEMA feature is left on for the best

sensor operation.

Standard and Non-Standard Settings

The Non-Standard settings can be changed at any time after the sensor is

powered up. These settings have 7 variables and follow in sequence with the

Preset/Variable chart (see reverse side of this sheet). The Altitude and TEMA

feature can be changed without entering into the Non-Standard mode.

The Standard Settings (see reverse side of this sheet) are factory set and

cannot be changed. Like the Non-Standard settings, Altitude and TEMA can be

changed.

Select a Preset (from the STDSET Menu)

1. Press + and hold (at least 5 seconds) until the sensor enters the

edit mode.

2. Press 2 times. You will enter the “STDSET” Menu.

3. Use the Up/Down Rocker Button to select the Preset number.

Use the

“Preset” chart (on reverse side of this sheet) to select the desired

“Variables”

4. Press to lock in selection then press to return to monitoring mode.

For Custom Settings (from the NONSTD Menu)

1. Press + and hold (at least 5 seconds) until the sensor enters the

edit mode.

2. Press 2 times. You will enter the “STDSET” Menu.

3. Use the Up/Down Rocker Button to toggle to the “NONSTD” Menu and

press .

4. Use the Up/Down Rocker Button to scroll through the 8 variables. The

variables begin with customizing the ppm levels and end with hysterisis.

5. Press to move through variables. Use the Up/Down Rocker to toggle to

desired setting.

6. Press to lock in selection then press to continue to next Variable.

Software Operation

Your new Innovair™ CD100VC CO2 Ventilation Controller uses state-of-the-art

dual beam Absorption Infrared™ Technology. This patented technology

provides a stable, accurate and reliable sensor.

The sensor is also equipped with Engelhard Sensor Technologies’ patented

TEMA (Time Extended Measurement Algorithm) software. The TEMA software

will automatically sense and adjust for any sensor drift minimizing calibration

frequency to once every five years.

The Ventilation Controller is shipped with 9 preset settings (named Standard

Sets) and one setting for customizing (named Non-Standard). Two additional

settings are available; altitude adjustments and TEMA (on/off). These two are

accessible without entering the Standard or Non-Standard settings.
