Product review (1 stars): DO NOT BUY THIS JUNK
This was total garbage from the beginning.  No instructions, contractor had trouble installing, didn't have all the parts, just a total mess.  After about 4 months this thing would just start beeping for NO reason.  Then after about 8 months the beeping noise stayed on and would not stop, something went really bad.  The only way we could get the noise to stop was to turn off the power.  Now it is all black, controller does not work so it is USELESS.  Move past this page and look somewhere else if you want quality, this is definitely not it!
