The lower thermostat on a water heater is the component that heats the water and is usually located near the bottom of the water heater. It is responsible for regulating the temperature of the water and typically has a range of temperatures that can be set.
It should be set to the desired temperature according to the manufacturer’s instructions, which can range from 105-140 Fahrenheit. The lower thermostat has a high limit switch that will shut off the water heater if the water gets too hot.
It is important to keep an eye on the temperature of the water heater and adjust the thermostat accordingly in order to avoid any potential safety issues.
What is the bottom dial on a thermostat?
The bottom dial on a thermostat is the fan control. The fan control sets the speed of the fan, allowing you to move the air in your space more quickly or more slowly to achieve your desired temperature.
Depending on the make and model of your thermostat, the fan control options may include ‘On/Auto’ or ‘Low/Medium/High’.
The ‘On/Auto’ setting keeps the fan running continuously to ensure that air is constantly circulating in your space, while the ‘Low/Medium/High’ setting allows you to set the speed of the fan. If you are cooling your space, having the fan on a higher setting will help to cool the space faster, while a lower setting will reduce moisture buildup in the air.
On the other hand, if you are heating your space, having the fan on a lower setting will help to maintain a comfortable temperature, while a higher setting will move the heat around more quickly.
No matter what fan control setting you choose, it is important to remember that the fan will not affect the temperature setting of the thermostat. It will only affect the flow of air throughout the space.
How do I know if my hot water heater thermostat is working?
