FriwaMaster
1 Hydraulic system
1.1 Description
In systems with a high power demand (e.g. hotels) several DHW
heat exchange modules (Friwa modules) are operated in a
cascaded mode. The individual modules are switched on and
off by means of valves according to demand. The FriwaMaster
measures the overall flow rate and switches on or off the
individual modules according to the flow rate. Special algo-
rithms assure that the modules are equally used.
