If the Johnson Controls Thermostat displays 'The controller provides an error when trying to upgrade firmware', it means the firmware on the USB drive is below the minimum required version. Please use firmware version 3.0.2.xxxx or higher. A reboot is required to clear the Firmware Mismatch fault that occurs.
Why does my Johnson Controls Thermostat say 'Open Window'?
If your Johnson Controls Thermostat displays 'Open Window', it means the switch connected to the BI configured for Open Window is sensing that the window is opened, and control has shut down. Close the window to resume control. Check sensor functionality with an ohmmeter, and verify the wiring to the TEC. Order replacement units and return the affected devices to Johnson Controls under the RMA program.
