DO NOT PLACE THE EA-400 INSIDE A COOLER OR FREEZER
An external probe must be used for cooler / freezer application
The EA-400 comes in both 12V and 24V versions, please sure you have the proper voltage for your application.
To unlock the unit press down both the "Alarm Silence & Enter" buttons for a second, and release at the exact same time.
