4.7 Safety
4.7.1 AQA Safe valve
The AQA Safe valve closes the waste water
valve in the event of a power failure and thus
protects against water damage caused by rinsing
water, especially when the rinsing water is being
drained by a pump that stops functioning when
the power fails.
4.7.2 AQA Watch alarm function
The programmable AQA Watch alarm function
monitors the water supply to the building and
issues a warning message if low flow rates
(< 60 l/h) over a longer period of time (> 10 min-
utes) indicate a problem in the pipe network (e.g.
leakage, dripping drain tap or leaky toilet cistern).
4.7.3 AQA Stop – moisture on oor
sensor only responds to drinking water (minimum
conductivity of 500 µS/cm).
AQA Stop – water quantity limitation
To minimise water damage, the control valve
water volume.
If larger quantities of water are to be drawn
swimming pool, etc.), this function may need to
be deactivated or acknowledged after activation.
AQA Guard Wireless Sensor (optional)
Installation of up to 10 AQA Guard Wireless
Water Sensors (order no. 11772) in the building
to receive an alarm message in case of leakage.
