Supplies for Installation

WiNG-CO2 Sensor

Small flathead screwdriver

Installation Instructions

1.  WiNG-CO2 sensors can only be seen by an RLE WiNG controller with the 

following firmware requirements:

Device

Minimum Required Firmware Version

WiNG-MGR

v3.6.0

WiNG-MGR v2

v1.0.27

BMS-WiNG

v3.2

 

If your device’s firmware is older than necessary, download the latest 

firmware from the RLE website (rletech.com) and update your device.

2.  Remove the lid from the sensor enclosure. The lid has one large tab at the 

top and two small tabs at the bottom that secure it to the sensor base. 

Squeeze the top of the lid to release the large tab. Pivot the top of lid out 

from the base and gently separate the two bottom tabs from the base.  

NOTE: 

The serial number is printed on a white label on the outside of the 

sensor lid. The serial number is unique to each sensor and you will need to 

refer to this number throughout the life span of the device. 

3.  Remove the circuit board from the base to expose the mounting holes. 

Before you take it apart examine how the board fits into the base. You’ll have 

to put it back into the base so make sure you have a clear understanding of 

how it was assembled before you remove it.  

4.  To remove the board pull the circuit board clip out to relieve the tension that 

holds the board in place. Angle the board up and then pull it to the right to 

remove it from the base. Move the board slowly and gently to get it out of 

the base without damaging any circuitry.

5.  Secure the base in the desired location. Select a location for the transmitter, 

keeping the following in mind:

• 

For best reception, mount the enclosure base as high off the floor as you 

can with the most direct/clear line of sight to the controller.

•  Do not mount the transmitter behind metal objects. 

6.  Put the circuit board back into the enclosure. Angle the board in under the 

lip of the L brackets and as far down as it will go against the plastic pegs at 

the bottom of the enclosure. Guide the board so it is parallel with the base. 

Pull the circuit board clip out and push the board down until the board clip 

securely snaps into place. The board is a very tight fit in the enclosure. Work 

slowly and gently so the board isn’t damaged.  

7.  Each WiNG-CO2 sensor 

must

 be configured for its environment during 

deployment. The sensor will not operate properly until all steps of this initial 

configuration procedure are completed:

a.  Remove the batteries from the sensor. Wait 20 seconds for power to 

dissipate.

b. 

Compensate for Altitude: Altitude has a significant impact on CO2 

readings - for example, a CO2 reading taken at 10,000ft will have a 

measurement change of 44% from the same reading taken at sea 

level. Each WiNG-CO2 must be configured to compensate for the 

altitude of its location.  

 

Use a small flathead screwdriver to point the arrow of the rotary switch 

to the setting that corresponds with the closest altitude setting:
