The fan on the E+ will only work if the room is above the room set point by 2 degrees Celsius and the door interlock is closed. Please refer to the E+ electric unit heater installation manual (https://www.reznor.co.uk/wp-content/uploads/2024/08/Reznor-e-Installation-Manual-EN-2024-06-D301600-Iss-0-print-quality-1.pdf) for more information.
Why is the E+ fan not operating when set to "Fan Only" mode during the scheduled time?
