Description
Thermostat TH 470 for additional cooling is operated by changes of arching of bimetallic spherical cap (bimetallic membrane in following text). Arching of bimetallic membrane is changed by environment temperature and this change is transferred to thermostat switch mechanism.
Thermostat TH 470 is made as one unit. Sensor and the electrical switch system are assembled, adjusted and enclosed in the thermostat body. Thermostat is installed into specified hole in the cooling system of engine. To install it, use thread M 22x1.5 on the thermostat body and hexagon head OK 27. Thermostat is designed for single-wire circuit. Thermostat head with flat pins is connected permanently with thermostat body.
Thermostat is supplied with sealing ring diameter 22x27. If corrosion protection of connecting terminals by cover filled with plastic lubricant is required, specify it in order as Terminals cover.
