Hello I hooked upu thermostat to my FS enviro empress stove I set it up and tested it on the on/off setting. I set my stat to out stove on at 65 degrees. It goes on perfectly but it don't stay on what could be the problem. Could there be a setting on the thermostat to make it chit down? I thought a thermostat has to have a temp set to go on an a set temp to go off . Could the thermostat be set to go off too soon? Any information would be great thank you
