The value ZIR07 FLOW RATE CIRCULATION can be entered in l/min or be
determined by the calibration ZIR06 CIRC. CALIBRATION, see
6.5 "Calibration of the circulation volume" on page 39 .
If the flow rate moves in the range of maximum flow rate (switch-off
threshold) ZIR09 MAX FLOW TAP SUPPORT minus tolerance ZIR05 TOL-
ERANCE CALI. CIRC, a 3-minute timer starts. Once this time has
elapsed, the WWC circulation pump is stopped in order to determine
the current flow rate.
In order to avoid unnecessary cycles of the WWC circulation pump, a
minimum runtime ZIR11 RUNTIME CIRC.PULSECON and a minimum off
time ZIR12 OFFTIME CIRC.PULSECON are active.
The value ZIR07 FLOW RATE CIRCULATION can be determined by means
of an automatic calibration process ZIR06 CIRC. CALIBRATION.
The following can be selected:
n
0: Off. No calibration.
n
1: Manual calibration, reset value to "0" after calibration has taken
value.
n
2: Automatic calibration, each Monday at 2:00 am.
If calibration is active, its status can be followed under ZIR09 STATUS
CIRC. CALIBRATION:
n
0: Inactive – No calibration made to date, or last calibration no
longer valid.
n
1...8: Measurement 1...8. - If measurements 1..4 ok, transfer to 9,
otherwise conduct measurements 5...8 and then evaluate.
n
9: Calibration successful
n
10: Start
n
11: Error – Flow despite pump being switched off.
n
12: Error – Flow rate fluctuation too great when the pump is
switched on.
A maximum of 2 measurement blocks consisting of 4 measurements
are carried out in relation to calibration of ZIR07 FLOW RATE CIRCULA-
TION. If the measured values do not indicated any deviation greater
than the defined tolerance ZIR05 TOLERANCE CALI. CIRC, calibration
was successful and the value is displayed under ZIR07 FLOW RATE
CIRCULATION.
