Battery Status
Especially in businesses with a lot of traffic and strict sanitary regulations like restaurants, checking the battery on a regular level is really important. GROHE offers an easy way to manually check the battery status so that batteries can be re-ordered in advance.
Checking the battery status
- Cover around 80% of the sensor with your thumb.
- The diode lights up briefly and then flashes.
- Only when the light of the diode flickers, take the thumb away.
- Now a slow flashing follows, the number of flashes indicate the battery level.
4x flashing corresponds to over 60% capacity, 3x flashing over 40%, 2x flashing over 20% and 1x flashing below 20% of the battery capacity.
Low battery
- If the battery is very low, the indicator light in the sensor will flash.
- In this case, simply unplug the cable, replace the battery and reconnect the cable.
In buildings such as airports where the usage is very high GROHE recommends that a power supply should be installed instead of a battery pack.
Ending the battery check
- After the battery capacity check, the continuous run for thermal disinfection automatically begins.
- Caution: Risk of scalding! Check if the temperature lever of the tap has accidentally been set to "hot"!
- To end the thermal disinfection prematurely, simply place your finger back on the lower part of the sensor.
- The diode then gives off a long flash, after which the thumb can be removed from the sensor again and the continuous run is finished.
