Error, Program
Due to a new program version, problems with EEProm or problems
with one of the internal data buses, EEProm was initialised.
After this fault, it might be necessary to recalibrate temperature
measuring again.
Error, Lock
The message appears when the key pad is locked with a PIN. If the
message appears although the PIN function is not active, the key
pad cannot be initialised. If the problem is caused by one of the in-
ternal data buses, the mainboard or HMI unit must be replaced.
