The Dimplex PLXE Series heater has a window monitoring function that detects when a window is open to prevent unnecessary energy consumption. If the heater detects a sudden temperature drop, it reduces heat output. "Error Code 50 - Open Window Detected" likely indicates that the heater has detected a significant temperature drop, possibly due to an open window. To resolve this, close the window and clear the error message. If necessary, disable the window monitoring function as described in the manual.
