11.16 Basic system diagram 16:
1 collector array, 1 storage cylinder, circulation, anti-Legionnaire’s disease
System 16 has one collector surface, one
storage cylinder, one timer-controlled or
impulse-controlled circulation pump and one
Anti-Legionnaire’s disease function. The
control unit regulates the solar function
(temperature difference regulation), the anti-
Legionnaire’s disease function (thermostat,
timeframe fixed, preset period) and the
impulse-controlled circulation (impulse) or
thermal circulation (thermostat, 2
timeframes). Heat metering is also possible,
e.g. using an impeller flow meter.
For the anti-Legionnaire’s disease function
E2 is used as reference sensor.
