With time, the ABC function will tun e the readings back to the correct accuracy range. The default tuning speed is li mited to 30 ppm per week.

QUICK INSTALL

1. Select a mounting location away from ventilation sources. The sensor should be mounted on a vertical wall, about 4 1/2 feet above the oor.

2. Ax the backplate to the wall.

3. Wire the device. Refer to wiring diagrams on page 2.

4. Install Cover.

CW SERIES

INSTALLATION GUIDE

OPERATION

CW series wall mount CO2 sensors measure the levels of CO2, RH (if equipped), and temperature (if equipped) of air inside a duct. The CO2 sensor operates within accuracy specications for an interval of 5 years and can be eld calibrated. The temperature element is warranted to meet accuracy specications for a period of 5 years. RH equipped models feature a replaceable HS Series humidity element that is warranted to meet accuracy specications for a period of 1 year. To maintain accuracy, all vents must remain clear and free of dust, debris, etc.

DIMENSIONS

INSTALLATION

1. Remove the cover by pressing the tab at the top of the sensor while pulling outward from the top of the cover.

Observe handling precautions for static sensitive devices to avoid damage to the circuitry which

2. Remove the backplate by unfastening the sensor from the bottom of the backplate and pivoting the sensor outward.

3. Punch out desired wire openings in the backplate.

All optional connector blocks are shown here for clarity.

4. Position the sensor vertically on the wall, 4 1/2 feet above the oor. Locate away from windows, vents, and other sources of draft. If possible, do not mount on an external wall, as this might cause inaccurate temperature readings.

5. Mount the backplate onto the wall using the screws provided.

Five screwholes available; use a minimum of two for secure mounting.

All optional connec tor blocks are sho wn here for clarity.
