No hot water.
The safety switch has tripped. Remove the cause of the fault.
Protect the heating system against overheating
by opening a draw-off valve downstream of the
appliance for one minute. This cools down the
heating system. Activate the safety switch by
pressing the pushbutton on the safety switch
(see also chapter "Installation/ Commission-
ing").
Fault in the electronic safety equipment. Replace the appliance.

The set temperature is not achieved.
The set value transducer or the connecting cable
is faulty. The connecting cable is not plugged in.
Plug in the connecting cable; replace the set
value transducer if required.
Anti-scalding protection is activated. Deactivate the anti-scalding protection.

The set temperature is not achieved. The appliance is at its output limit. Reduce the flow rate. Install a flow limiter or
check the flow limiter.
Green LED flashing,

nently on
No warm water, when flow rate higher
than when switched on.
The heating system is faulty. Check the resistance of the heating system and
replace the appliance if required.
The PCB is faulty. Replace the appliance.

Required temperature > 55°C is not
achieved.
The cold water inlet temperature exceeds 55°C. Reduce the cold water inlet temperature to the
appliance.
