Emergency operation

If the valve must be adjusted by hand because of an
error that cannot be corrected (e.g. the batteries are
low and no replacements can be found at the time),
it is done as follows:
• Remove both batteries.
• Remove the adjustment knob by pressing on
the position indicated with (B).
• Set the adjustment knob on the pin indicated
with (A).
• Turn the adjustment knob: clockwise = warmer,
counterclockwise = colder.

10 Maintenance and cleaning

The product is maintenance-free besides possibly
requiring a battery change. Maintenance or repairs
are only to be done by trained professionals. Clean
the product using a soft, clean, dry and lint-free
cloth.
To remote heavier contamination, make the cloth
damp with lukewarm water. Cleaning agents that
contain solvents are not to be used because it can
harm the plastic housing and the labels.
