We are not pleased with this product . the unit was installed by a certifeid electrician and it has barely been used ( maybe  two ours in total) . It was installed in brand new home ,It only works on the low speed and the light is not working and no light in the wall control unit .We also tried the make it work with the remote control uint (good luck NADA ) . Payed $ 660. 79  for it  and it is not working properly .Hope to here from you ASAP.
Thanks in advance
