There are two ways to reset your Terra Smart WiFI Thermostat. If you’d like to learn how to reset your Terra thermostat, read the list below or watch the video included.
When the thermostat reads “ER2,” the floor sensor has a short circuit or has a loose connection. Your electrician must secure connections and test the probe using a multimeter set to the lowest possible ohms scale. The resistance reading should be between 7 and 17 ohms. If a short is found and a backup sensor probe was not installed, you can bypass the error message by setting the thermostat to read the air temperature instead.
