Description
The Lochinvar & A.O. Smith 100108421 Lower Thermostat with Cover WH9 is a temperature controller that is installed on heating equipment to detect and control the amount of heat. It reacts to variations in temperature and triggers the control system to ensure that it is operating correctly when used in boilers and hydronic HVAC systems. The thermostat is placed in the lower part of the appliance where temperature feedback is needed and is surrounded by a protective cover to protect it against direct exposure.
