: Calculation of the flow rate from the pump speed. To do this, the displayed flow rate values are entered
at two measuring points (pump speed min. and max.).

: Determining the flow rate using a pulse water meter. The flow rate of the pulse water meter in
litres/impulse is entered.

10.3.9 Circulation
Switches a circulation pump on and off on a temperature and/or time
controlled basis. The pump must be connected to output
R1
.
Temperature control
: If the temperature in the circulation return falls
below the T
on
value, then the circulation pump is switched on until the
T
off
temperature is reached.
Time control
: The circulation pump is switched on when the current
time lies within one of 3 configurable time windows.
Temperature and time control
: The circulation pump is switched on
when the switch-on conditions for the temperature
and
time control are
satisfied.
Note
Install the circulation sensor at least 1.5 m (60 inch) away from the
storage tank to avoid false measurements due to heat conduction of the
pipes.
