These thermostats are single-pole thermal switches designed to control temperatures in gaseous environment e.g. hot air heaters or other enclosed spaces with high levels of dust and humidity. They are also suitable for cooling and air-conditiong, combined with electric valves to control steam or hot water heating , as well as sensors in a heated space. The essential part of the thermostat is a reliable mechanical system, which does not use any power. In comparison with electronic system, this thermostat has low operation and maintance costs.

Thermostats TH 480 together with other equipment are designed to control water temperatures in e.g. hot water tanks combined with water heating. It is a reliable and cheap mechanical system that controls temperature and lowers energy consumption, thus it saves operating expenses. It is an effective means of protection against overheating and overloading.

The thermostat TH 472 is designed to control temperatures in a liquid environment. The electric contact system enables quick-break switching AC or DC circuits on/off. When used in cooling systems of combustion engines, it saves fuel as there is no power drain for permanent cooling and it increases engine effectiveness.

These thermostats are single-pole thermal switches based on the principle of different dilation of two different metals. They are designed as electric circuit switches but are not to be used as a main switch. The essential part of these thermostats is a reliable mechanical system, which does not use any power. In comparison with electronic systems, these thermostats have low operation and maintenance costs.
