    An E101 non-locking fault on your Envirovent Fan indicates a defective pressure sensor extract fan or blocked/kinked blue pressure hoses. In this state, the system switches to constant RPM control, and the preheater turns on when outdoor temperatures drop below 0°C. To address this: * Disconnect the unit from power. * Examine the blue pressure hoses (and pressure tubes) for fouling, kinking, or damage.

    The E103 non-locking fault in your Envirovent Fan indicates a bypass fault. This might be due to the current being too low (possibly from a stepper motor not correctly connected or effective) or too high (potentially from a short-circuit in the wiring or stepper motor). To resolve this: * Disconnect the unit from power. * Check the stepper motor connection, and replace the wiring or stepper motor if necessary.

    If your Envirovent Fan displays an E104 locking fault, it indicates the extract fan is defective. As a result, both fans and the preheater (and postheater, if applicable) will switch off, and the system will attempt a restart every 5 minutes. To resolve this: * Disconnect the unit from power. * Replace the extract fan. * Restore power to the appliance; the fault should automatically reset. * Check the cabling.

    The Envirovent Fan displaying an E100 non-locking fault suggests a defective pressure sensor supply fan or blocked/kinked red pressure hoses. When this occurs, the system switches to constant RPM control, and the preheater activates at outdoor temperatures below 0°C. To troubleshoot: * Disconnect the unit from power. * Inspect the red pressure hoses (and pressure tubes) for any fouling, kinking, or damage.
