Thermostat Distribution Beam

back to products


The thermostat distributer AD-THV 10 serves the temperature-dependent regulation of a circulation pump and, at the same time, supplies an electric heating rod to a maximum of 2000 Watt (for higher performance, an external power-relay can be mounted). With this simple regulating device, a small amount of water can be heated electrically and, on reaching a temperature limit, a circulation pump can be switched on to a maximum of 100 Watt. The small amount of water heated in this way is now pumped into a large buffer supply tank (i.e. water storage tank in the heating). Due to this simple loading pump principle, the buffer supply tank is completely heated through. The known layering in the storage tank (warm at the top cold at the bottom) is therefore significantly reduced. With permanent operation, the buffer supply tank can be brought to an even maximum temperature. The AD-THV 10 requires a PT1000 resistance sensor for the temperature measuring, which is contained in the package. The switch point of the pump relay can be adjusted via an internal potentiometer. The switching hysteresis is permanently set.


Complete through stratification of water reservoirs on the charge pump principle. Works best in conjunction with the flow heater set AD-DLE.
