My new apartment has a built-in heater/ac unit. I'd like to build a primitive thermostat for it (keep it off during the day, but on in time for me to get home from work, etc), like I did with the window units in my old apartment with X10.
But I have no idea what this is or how to deal with it: plug:It looks like a standard US 3 prong plug, except one of the prongs is rotated 90 degrees. I measured the voltage at the socket at 214V AC. Can anybody offer some pointers about what this socket is, and which / if I can get an X10 module to control it?
