  Preston MillerAug 17, 2025
  If your Johnson Controls Thermostat displays the ERROR_REMOTE_SENSOR_SHORT message, it indicates a potential issue with the remote temperature sensor. Start by checking the wiring of the remote temperature sensor, specifically looking for any shorts between the thermostat terminals RS and SC. If a short is found, rewire the remote sensor correctly and then power cycle the thermostat. Also, verify if the remote sensor is either malfunctioning or damaged.
