Power supply requirements

CAUTION! Make sure that you connect the power wire only to the 24V terminal. Connecting the power wire to the output terminal may result in equipment damage.

The CO2 sensor is designed to operate with a nominal 24 Vac supply. The power supply should maintain the voltage between 20 to 26 Vac.

Wiring the wall-mounted CO2 sensor

DVC setpoint potentiometer on economizer module can be adjusted as follows:

0% - 500ppm, 50% - 1000 ppm,

100% - 1500ppm

The outside air damper will modulate from minimum position setting to up to 100% while attempting to maintain the CO2 setpoint.

To connect the wall mounted CO2 sensor, Refer to the wiring diagram provided in the unit.

Wiring the duct-mounted CO2 sensor

1.Connect the DCV signal lwire to the connector DCV of the ECA

2.Connect the power according to the guidelines in Power supply requirements.

To connect the wall mounted CO2 sensor, Refer to the wiring diagram provided in the unit.

Mounting the wall-mounted sensor

1.Select a proper location in the room to mount the CO2 sensor. Look for an interior wall with good air circulation, approximately 1.4 m from the floor.

2.Remove the back plate from the sensor and thread the power wires and output signal wire through the hole in the back plate.

For surface wiring, make cut- outs with pliers to the thinner section of the upper or lower edge of the back plate and to thread the wires through.

3.Mount the back plate to the wall with screws. Note that the arrow on the back plate shows the mounting direction.
