Safety Instructions
• varmo TZ eco is designed for use in
buildings.
• Operate varmo TZ eco only as de-
scribed in the user manual.
• varmo TZ eco should only be put to use
in a dry and dust-free place, away from
direct sunlight.

Warning
Never recharge batteries, do not short
circuit them, do not take them apart - Risk
of explosion! Remove dead batteries from
the device immediately.
Do not use old and new batteries together.
Clean battery and device contacts before
inserting if necessary.
Keep batteries away from children. Avoid
contact with skin, eyes and mucous mem-
branes. In case of contact with battery
acid, rinse the affected areas immediately
with plenty of water, and seek medical
attention immediately.
Inserting / replacing batteries
Remove the battery cover by simply pulling
it off. Now insert the batteries. Pay attenti-
on to the correct polarity! At a later battery
change, the conguration of your varmo TZ
eco is maintained.

Help and error messages
Error Cause/Solution
Batteries do not have enough power.
Replace batteries.
Heating
element
does not
warm up.
Is the boiler water temperature O.K.?
Valve does not open, is it calcied after
the summer pause/heating pause?
Adjust the temperature of the boiler
water. Remove the varmo TZ eco,
move the valveback and forth per hand
or with a tool.
Heating
element
does
not cool
down.
Valve does not close completely. It
may be that the closing point of your
valve seat has shifted.
Adapt again (see “Adapting”) Move
the valve stem several times by hand,
it may be that adaptation is impossible
because your valve is calci ed or the
seat no longer performs its function.
Pressure
piece falls
out (This
can also
cause an
E1-error).
Due to an endless thread the pres-
surepiece, which is situated at the
bottom, can fall out if the device has
not been afxed on the valve.
Put in the pressure piece. The device
can be adapted by removing and
inserting the batteries. The endless
thread is rotating now and xes the
pressure piece again. Just install it to
the radiator and adapt it once again.
