I would do two things. The F-key can be tricky as it may require a 'double' press. Try turning a light on when a door is open. Second, get an extension/adapter (not power surge type) and make sure your appliance module and PSC05 are plugged into it. This way you know you don't have a signal suck problem. I believe the PSC05 light should blink when a command is given to it.
