The error can only be reset in
the test mode as follows:
First, press the

displayed. Then press the
y
button 1 time. Finally push the
z
button to exit the test mode.
Notes:

action number executed" will
contain the latest action
number executed.
• [F-08] "Underfloor heating
screed dry-out program
enabled (1)/disabled (0)" is
always cleared to 0 (disable).
This means that in case a
second time a "Underfloor
heating screed dry-out
program" must be started,
[F-08] needs to be set again.
