Indoor Air Quality Monitoring
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.
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 cannot be accessed or changed by the user and is recharged
automatically when mains power is restored.
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.
WiFi Network Features
After you’ve connected the EL-WEM to your WiFi network, if the power button starts flashing again it means the monitorable to connect to the network to upload data. The EL-WEM will automatically try to reconnect, WiFi network is available. If you want to perform an immediate upload to the Cloud and your netw the power button. This will create an audit mark in the event record. To reconfigure the WiFi settings (use a different WiFi network), press the Setup button on the base of the unit for 3 seconds.
