Intended use
With Comet Z-wave, you have acquired a programmable radiator thermo­stat, which can be used to regulate temperature in closed rooms and thus
can contribute to a reduction in heat energy. Please use the regulator for
this purpose only.

Description
Comet Z-wave is a Z-Wave radio standard compatible
energy-saving radiator thermostat.

Use
The installation of the Comet Z-waves can easily be installed on all known
valve bottom sections; without dirt or water spots because the heating
circuit is not interrupted.

1. Fully unscrew the old thermostat, loosen the fi tting
and remove from the valve.

2. 2. Remove the battery cover, by pressing it upwards on the marked spot
(1) and take it off its hinges (2).

(1)

(2)

Install the batteries as shown. Do not use rechargeable batteries!
Ensure correct polarity! PREP appears on the display. The motor will
start completely in order to facilitate installation. As soon as the regulator
is installation-ready, INST appears on the display. The fl ashing radio
symbol signals that the device is ready to be enrolled. Start the enrolment
procedure (Inclusion) on your Gateway/Controller in order to include the
device in the network.

3. Screw the union nut (ring on product) on the valve. If the union nut does
not fi t on you valve, you probably need an adapter.

4. Press the button in the battery compartment. The energy-saving thermo
stat shows ADAP in the display and carries out an initialisation run.
After initialisation, the energy-saving thermostat shows the main screen.
INFO When an error occurs, an error code is shown.
Look in the „Help“ table.

Help and error messages

Problem 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 calcifi ed after
the summer pause/
heating pause?

Adjust the temperature of
the boiler water.

Remove the Comet
Z-wave, move the valve
back 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
calcifi ed or the seat
no longer performs its
function.

Pressure
piece falls
out (This
can also
cause an
E1-error)

Due to an e ndless
thread the pressure
piece , which is si tu­ated a t the bot tom,
can fal l out if the
devi ce has not been
af fi xed on the
valve.

Put in the pressure
piece. Press the Button
for 3 sec.
The en dless thr ead is
rot ating now a nd fi xes
the pr essure pi ece
again . Just ins tall it to
the ra diator and a dapt
it once again.

E1-E3 Press the button for 3 seconds. The fault indication

is deleted. The device moves to the mounting posi­tion (display shows PREP or INST).

E1 No adaptation

possible.
Comet Z-wave is not
installed to the heater.

Is the installation OK?

Install Comet Z-Wave
to the heater.

E2 Valve stroke is too

short.

Open and close the
valve several times
manually or replace the
batteries.

E3 Motor movement is

not possible.

Does the valve stem
move freely?
