So in 2003 I installed a mat in our basement bathroom. This included the TH111-P-GFI controller. Recently the controller started acting up. After a few e-mails and tests it was determined that it definitely was the controller. I was totally surprised that after basically 20 years I was offered a new controller at 1/2 price! It arrived very quickly and was easy to hook up. We are back to having a nice warm floor!!
