TROUBLESHOOTING
Problem: Water runs continuously
Possible Cause
Interfering object is in
monitoring range
Defective electronics module
Improper electronics module
External water pressure too high
Solenoid valve inoperable
Problem: Water flows although shut-off screw is removed
Possible Cause
Electronics module is inoperable
Water drops on infrared window
Problem: Faucet turns on by itself
Possible Cause
Infrared window is dirty or scratched Clean window with smooth cloth
Faucet is influenced by
room environment
(mirror, stainless steel or
glass sink, etc.)
Input line pressure fluctuates
Problem: Faucet is leaking water
Possible Cause
Connections between housing
and braided
Connection between braided hose Check rubber washers
and inlet supply are loose
Connection between valve body
and solenoid valve is loose
Faucet drips, solenoid valve
does not close
Problem: Temperature can not be adjusted properly
Possible Cause
No, or too little hot or cold water.
Supply valves are not fully opened
Inlet water line filter is dirty
or blocked
Braided hose is kinked
Backflow preventer in faucet
inlet is blocked
Temperature of hot or cold water
supply is too low
Hot water temperature not sufficient Reverse hot water limiter
Braided hoses are connected
improperly (cold to hot & hot to cold

Faucet Adjustments
Operating modes and sensor ranges can be adjusted with a manual
operation through the infrared sensor. A traditional lavatory faucet is
shown as an example. Faucet adjustment operations apply to all models.
Alternatively, operating modes and sensor ranges can be adjusted with
a handheld PDA and Geberit Commander

In order to set the operating modes, the faucet needs to be placed into
"Manual Setting" mode. At this time, operating modes can be changed
within the next 30 minutes.The following is a functional diagram to show
the different settings available for manual faucet adjustment.

regardless of hand presence detected.
The faucet will shut off 60 seconds after the
detection of the last hand presence.
The faucet will shut off 180 seconds after
the detection of the last hand presence.
