Warnings/Error Messages

Warnings/Error Messages
In addition to normal information, e.g. water tem-
perature, the K4 control also displays warnings and
error messages. Warnings and error messages can
be distinguished as follows:
Warnings (e.g. A01) signal unusual operating
statuses. Although the operating status concerned
can somewhat restrict shower performance, you can
still take showers in most cases.
Error messages (e.g. F01) also signal abnormal
operating statuses. Here shower operation remains
fully interrupted – as against warnings – until the
malfunction has been cleared. This prevents any
hazards to the user.
List of possible warnings/error messages on the K4 display:
Warnings
A01 Thermostat motor current too low
A03 Thermostat motor current too high
Resistance of thermostat potentiometer too low

A07 Resistance of thermostat potentiometer too high
