The unit is the older model that doesn't have a remote. You have to press the button on the wall unit. Lately it started to turn itself on and then after a few minutes it turned itself off. But today it turned itself on and keep going. We tried to turn it off at the wall unit but it wouldn't work. We then turned off the main for a few minutes and turned it back on and it still automatically started running. Please help as we have had to turn on of the main switches off but that has also affected half the hours sockets. Thanks and much appreciated.
