We have a very large rec room that required 3 mats to cover. Thermosoft told us to hook two of them directly to the thermostat and the third use a power module that is hooked to the thermostat. The 2 mats work great but the one through the power module keeps tripping and shutting off. We have checked the floor continuity and it is fine. Thermosoft has sent us a couple different power modules none work. My husband tried bypassing the main thermostat to see if the floor mat worked it worked fine. We have had the floor in 3 years now and that one section has never worked right. At first thermosoft told us that they had sent us the wrong power module to begin with but none of the others have worked as well. Has anyone else had this problem with large areas?
