parameters could cause
the heater and therefore the
system to malfunction. For
this reason, only a qualified
technician who has in-depth

this menu of parameters available to
the
qualified technician for diagnostic
and adjustment of the appliance to the
system.

the display in Figure 16-1, will start to
show the icon

5. press and release the RESET
button to confirm the amended
