[QUOTE="seajayess, post: 28021, member: 603"] Do the 3xpair go th the CU the L/N to the CU room stat to the CU You will need to feed possibly three contactors from the CU then connect the three mats to the contactors and use the stat to energise the contactor. If all the cables at the stat go back to the CU you have enough cables to do it. If not the L/N possibly go back to the CU and may be the roomstat goes back to somewhere near the CU if so put the L/N on a 20 Amp breaker through a contactor use the roomstat cable to feed and return switch line back like a loop plate to a contactor I know the load is just over 20 Amps but it would be worth a try as the supply will proberbly be more than 230 and this would lower your Amps are you sure the mats are 200 watts per meter as devi mats are only 100 watts per meter CJS [/QUOTE]
