Ideally, you should replace the battery once you see the low battery warning to avoid any interruptions in your HVAC system's operation.. Replacing the batteries on your Emerson thermostat refreshes its settings and enhances the displays. Simply follow these steps. Turn the power off. Flip to the back and unscrew the cover. The battery port will be revealed at the top portion of the thermostat. Pull out the old batteries. Make sure the port is dry.
