6 Do Not Disturb Mode

Your WEM contains an alarm sounder that you can activate from the EasyLog Cloud, to give an audible warning if the IAQ level is Poor or Inadequate. There is also an option to set a time period each day when the status ring and sounder are turned off.

7 Low Power Mode

The EL-WEM contains a back-up battery that can power the unit if mains power is lost. When running from the battery the EL-WEM goes into low power mode, and will upload data to the Cloud once an hour, although notifications for poor indoor air quality will be sent immediately. It is not possible to enter configuration mode or calibration mode until mains power is restored.

When your WEM is in Low Power Mode you may get `Connection Lost’ notifications from the Cloud (if you have set them up) as in Low Power Mode it doesn’t connect to the Cloud as frequently as normal.

The battery is intended as an emergency backup only and should not be used to power your EL-WEM for long periods.

The battery cannot be accessed or changed by the user and is recharged automatically when mains power is restored.

8 Calibration Mode (EL-WEM+ only

The carbon dioxide (CO2) sensor in the EL-WEM+ is extremely accurate and to maintain this accuracy it should be calibrated every 6 months.

First, provide as much fresh air as possible to the EL-WEM+, for example place it next to an open window. Then press and hold the power button for 10 seconds; the sounder will beep and the status ring will turn white.

The calibration process is automatic and will take a little while; when it’s complete the sounder will beep again and the EL-WEM+ will return to its normal monitoring mode. If for any reason calibration fails to complete the sounder will beep 4 times at the end of the process. You should then ensure the supply of fresh air is adequate and restart calibration mode.

9 WiFi Network Features

After you’ve connected the EL-WEM to your WiFi network, if the power button starts flashing again it means the monitor has been unable to connect to the network to upload data. The EL-WEM will automatically try to reconnect, but you should also check if your WiFi network is available. If you want to perform an immediate upload to the Cloud and your network is available, do a short press of the power button. This will create an audit mark in the event record. To reconfigure the WiFi settings (e.g. to change your EL-WEM to use a different WiFi network), press the Setup button on the base of the unit for 3 seconds. This restarts the setup process explained in section 4 above.
