Description
The A.O. Smith 9004238215 Upper Probe is a part of several HVAC systems that gauge and control water temperature at the upper part of a water heater tank. This probe measures the temperature and sends the information to the control system without any error. The control system then uses this data to control the heating element in the water temperature maintaining the right temperature and correct power consumption. The Advantage of heaters with this feature is that the temperature of the hot water that is supplied to showers, dishwashers, or any other necessity is well-regulated without scalding.
