Belt has shredded and dragged the wires off the thermostat.The thermostat has 4 tags set at right angles to each other, only one grey wire to the heater is left attached.Have got one grey wire,one white wire marked TH and one white wire marked T11 hanging loose.Where do I go from here there’s up to 16 different permutations of 4 wires.I once got the wires wrong on one of these stats and when I switched the machine on the module blew so you’ve got to get them right first time.Help please.
