Introduction, Parts List, and Specifications Introduction The CO2 sensor is especially designed to work in conjunction with LG Energy Recovery Ventilators (ERVs). Real-time CO2 levels are detected and displayed on the sensor’s LCD. The CO2 sensor then sends the data to the LG ERV via the hard-wired connection cable coupled with the supplied 33-foot extension cable.
Installation and Wiring 1. Open the Case. To open CO2 sensor case, insert a flat-head screwdriver in the slot (see right), and gently twist. Figure 2: Removing the Cover. 2. Remove the CO2 sensor Printed Circuit Board (PCB). The installer needs to remove the PCB attached to the bottom part of the case before wall-mounting the CO2 sensor. To detach, push the support tabs out that are holding the PCB, lift the PCB up, and remove.
Wiring Procedure, Operation, and Troubleshooting Wiring Procedure 1. 2. 3. 4. Power down the ERV. Attach one male end of the extension cable to the female connection on the hard-wired cable. Attach the other male end of the extension cable to the CN-CO2 terminal on the ERV Main PCB. Reattach the CO2 sensor PCB to the bottom of the case (that has already been wall-mounted).
