The temperature controllers are used for controlling or limiting temperatures in residential and non-residential buildings, as well as in industrial areas. They're used for heating registers, panel and hot air heating and direct floor heating, as a limiting thermostat for air-conditioning systems and cooling systems, switchgear cabinet cooling, etc. as well as for temperature control in humid and dusty rooms. They can also be used for inaccessible room temperature setting for rooms in public buildings, such as schools, dayrooms and comparable applications.
