11.7 Basic system diagram 7:
1 collector array, 1 storage cylinder, auxiliary heating, return line monitor
System 7 has one collector surface, one
storage cylinder, one auxiliary heating
function and one return line monitor. The
control unit controls the solar function
(temperature difference regulation), the
auxiliary heating (thermostat, timeframe)
and the return line monitor (temperature
difference regulation). Heat metering is also
possible, e.g. using an impeller flow meter.
