my thermostat and other bits i have ordered offline from surrey have arrived today! was wondering if anyone could help me though? i have plugged the stat into the mains to see if it has worked and the powerlight has come one, i then plugged the heatmatt in and the green light hasnt lit up but if i turn it all off at the mains and then back on again the green light flicks up and goes off again so i was wondering if the stat is faulty? any advice!
