Flow alarm
Pool Relax offers two different variants for monitoring the flow alarm.
Automatic quitting of the flow alarm (default variant)
In this variant, Pool Relax evaluates a flow alarm not as a fault but as a normal operating state. In most swimming pool systems,
circulation does not take place around the clock but is only switched on intermittently. In this case it is normal for Pool Relax not to
receive a flow signal during times when there is no circulation.
Accordingly, Pool Relax signals the missing flow signal as a normal operating state and not as an alarm condition. The special
mechanism for signalling alarms is not activated (flashing display, acoustic alarm, etc.).
Dosing is blocked as long as there is no flow signal. After the flow signal returns and after the power-on delay elapses, Pool Relax
automatically returns to its normal control mode.
Manual quitting of the flow alarm
This variant is only intended for swimming pools in which circulation runs twenty-four hours a day without interruption. Pool Relax
evaluates a missing flow signal as a serious fault condition that is signalled by various alarm mechanisms.
Important: Even after the flow signal is restored, dosing remains blocked in this variant. Blocking is only cancelled after the flow alarm
is manually quit and the flow signal is restored.
Monitoring of the measuring water
The flow of measuring water is permanently monitored with a sensor, which is installed in the measuring chamber. The flow of water
moves the float up to the level of the sensor. The monitoring of the flow of measuring water cannot be deactivated. Dosing is blocked, if
there is no flow signal to prevent dosing into non-circulating water.
12.3
Power-on delay
After the Pool Relax device is switched on or after a flow alarm, the adjustable power-on delay time runs down. Pool Relax waits for
this time to elapse to give all measurement values time to stabilise. Dosing does not take place during the power-on delay. Normal
control mode only begins after the power-on delay has elapsed.
The power-on delay is displayed on the alarms page as follows:
Power-on delay

min
Power-on delay
Quit
The first line shows the time remaining of the power-on delay.
The second line lets you end the power-on delay prematurely by activating the quit button.
12.4
Alarm signalling
Pool Relax signals the alarm condition to the user by various mechanisms.
Noticeable flashing of the entire display
The flashing stops as soon as you touch the screen.
Automatic jump to the "Alarms" menu
The "Alarms" menu can be called up any time directly from the selection menu via the menu button.
Acoustic alarm signal
(provided that this function is activated for the respective alarm in the "Alarm Settings" menu)
The acoustic alarm signal stops as soon as you touch the screen.
Switching of the alarm relay
(potential-free switch output (max. 230 VAC / 8 A) for connecting external systems for the signalling or recording of alarm
conditions (connecting terminal 45/46))
