What is a progressive mixer characteristics curve ?

A mixer with a special 3D rotary vane design always produces the same pressure drop over the entire control range at different volume flows. This achieves a high control quality. This can be recognized by a quiet servomotor that can control a constant flow temperature even at low volume flows....

What does GEG compliant thermal insulation mean ?

Pipes and fittings must be insulated at 50% of their nominal diameter at junctions, crossings and central manifolds in accordance with the Building Energy Act (GEG). For heating circuit groups, this means a fully enclosing minimum wall thickness and separation of the flow and return lines. The Tuxhorn tubra®-PGM/PGR pump...

What are the advantages of setting up fresh water stations as a cascade ?

A cascade is the parallel connection of several individual stations.Due to the cascade design, the outputs of several stations can be added together. In this way, greater tapping capacities can be achieved. The hot water flow rate of a cascade can be controlled more precisely. The next station is only...

How does the control of the eTherm C work ?

The eTherm C relies on external energy management for its operation. The Fronius Ohmpilot or the AC Thor 9S are representatives of the modulating energy managers. This makes it possible to control the eTherm C continuously from 0-9000 W.In this process, the smart meters of the energy managers measure the...

What are the functions of the eTherm P and what is it used for ?

The main task of the eTherm P is to use own produced PV surplus electricity (current measuring sensor included in the scope of delivery) for heating of a buffer or potable water storage tank. The station has various control options, such as 0-10 V or SG-ready, and also various selector...

Overview of the external controllers of the eTherm C3/C9

The eTherm C requires an energy manager for intelligent PV surplus utilization. The following combinations are possible: Fronius Ohmpilot (0-9000 W modulating) MYPV ACThor 9S (0-9000 W modulating) Solaredge Smart Energy Hot Water Controller (0-9000W modulating) powerReducer-Set eTherm C3 (0-3000 W modulating) SMA Sunny Home Manager 2.0 (3-stage switching) Solar-Log...
