Help
Problem
Cause
Solution
Batteries nearly
dead.
Replace the batteries.
Radiator
will not
heat up.
Water tempera-
ture in boiler
okay? Valve will
not open after
heat was off for
the summer
– limescale
build-up?
Correct temperature of wa-
ter in boiler. Disassemble
the Radiator Controller.
Move valve tappet back
and forth multiple times by
hand or with a tool.
Radiator
will not
cool down
Valve is not clo-
sing completely.
The point where
your valve seal
closes may have
shifted.
Carry out adaptation again
(see “Adaptation”). Move
valve tappet multiple times
by hand – adaptation may
not be possible because
your valve may have
limescale build-up or the
seal may no longer be
functioning.
Compres-
sion piece
fell out.
(This can
also cause
an E1
error.)
Because the
device has an
endless screw,
the compression
piece on the
bottom can
fall out if the
controller is not
mounted on the
valve.
Insert the compression
piece. Start the adaptation
process using the
MENU
item or by removing and
reinserting the batteries.
The endless screw rotates
and tightens the compres-
sion piece again. Mount
device on radiator and
perform adaptation again.
-
Pressing any button deletes the error shown
on the display and starts the adaptation
process again.
Adaptation not
possible. The
Wireless Radiator
Controller/Timer
not mounted on
radiator.
Device correctly mounted
on radiator? Mount the
Wireless Radiator Control-
ler/Timer.
Valve stroke too
short or battery
power too weak.
Open and close valve tap-
pet multiple times by hand
or insert new batteries.
