What is the ER1 Out Error?
The “ER1 Out” error on a 3iE Thermostat means that the thermostat is not set up with the correct sensor probe functionality. This is a simple fix.
How To Fix the Issue
On your 3iE Thermostat, go to Menu > Settings > Advance Settings > Probes > External > Select “No Function.”
