AUTO 185-215°F Limit switch is used to control air temperature in which this device can work normally. It turns on and off automatically. The resulting temperature is controlled by adjusting output control voltage of the controller. When input low temperature reaches 190°F, relay module is energized and the heater starts to work. The switching temperature should be at least 5°F higher than the set point for it to work properly. This device will continue heating until temperature of its sensing line rising up to limit value or 10 minutes, whichever comes first, then turn off automatically,
