Flow control [water flow]

NOTICE!
Alarm during logical checking
Cause: Alarm during logical checking.
Fault: The flow control reports that a water flow exists,
although the circulating pump is off.
Measure: The controller triggers an alarm. The flow
control must be checked.
NOTICE!
No flow
Cause: No flow in the water circulation system.
Fault: There is for example no water in the system or a
ball valve is closed.
The controller switches the circulating pump off and
triggers an alarm.
Timer adjustments with two circulating pumps
If two circulating pumps are connected, then they must
always be started simultaneously via the time. A
delayed switching on of the pumps, resulting in
switching on at different times, is not permitted
because this leads to an error message at the control
so that consequently the second circulating pump does
not start.
Example: Both circulating pumps are stopped by the
timer. The pool has status [Stop] and consequently the
paddle switch signals are not evaluated by the con‐
troller. If the timer now starts Circulating pump 1, then
within 30 seconds paddle switch [1] must deliver feed‐
back relating to the water flow. The paddle switch [2]
delivers the signal [no water flow] (which is indeed cor‐
rect), but the control reports the error [No flow]. Hence
the circulating pump [2] cannot be automatically
started by the timer.
Remedy: Adjust the timer so that both circulating
pumps are started simultaneously. This prevents one
of the two circulating pumps from not starting.
[Water flow] monitors the circulating pump flow.
The flow control
[Flow Control] is used with a paddle switch or a thermo switch.

The two core cable of the flow checking device (paddle switch or
thermo switch) must be connected in the A-module to the
minal. If the contact remains set on
pump control, then the circulating pump is stopped after a delay
period and the control produces an error message. This error mes‐
sage can only be deleted in manual operating mode.
