7. Installation
The room thermostat must only be installed by a qual-
ified specialist. Installation must only be performed according to the applicable local provisions.
The room thermostat must not be installed near any
windows, doors, heat sources or ventilation openings.
Also avoid installation in locations where the device is
exposed to direct sunlight. This may falsify the measured room temperature. Keep a distance of approx. 1.5
m for this.
Never cover the room thermostat with any other ob-
jects.
The device is only suitable for vertical wall mounting.
We recommend a mounting height starting at approx.
1.5 m. Only install the device on a stable basis, e.g. masonry.
Observe the max. connection value of the room ther-
mostat; see technical data. The installed relay is potential-free.
The controller must only be installed when powered down.
For this, power down the electrical mains supply that is connected to the relay of the room thermostat (circuit protection
and FI-switch off) and secure it against unauthorised reactivation!
13
Check the mains supply line for voltage-freeness. Ensure
that no present electrical or water lines are damaged during
installation.
The same applies, if only low voltage is to be supplied
through the relay, since this may cause short circuit at installation!
Remove the battery holder at the bottom of the device. Turn
the housing screw at the bottom of the controller out only
until the upper shell of the room thermostat can be removed.
Do not turn the housing screw out entirely. There is the danger of losing the housing screw and the square nut. Now
pull the upper shell of the controller off of the base plate.
The base plate is attached on a recessed socket with the
two enclosed screws. The base plate has four indentations
for attachment for this purpose. Break out the two required
attachment openings with a suitable tool. Route the mains
line through the mains line opening of the base plate. Attach
the base plate on the recessed socket with the two enclosed
screws (figure 1). Check for tight fit of the base plate.
Strip 5 mm of the cable insulation. Connect the supply line
of the end device to the screw terminal NO (1) or NC (3) and
COM (2).
14
The installed relay is potential-free. The connection ex-
ample shows the connection to mains voltage 230V/
AC. Observe the maximum contact resilience; see chapter “Technical Data” and the operating instructions of
the device that is to be controlled via the room thermostat, on how to set up the circuits.
1 = Normally open contact (NO)
2 = COM (Common)
3 = Normally closed contact (NC)
L 230 V/AC, 50-60 Hz
E.g. recircula-
tion pump
Example
15
Push the upper shell onto the base plate (figure 2). Make
sure that the supply lines are not crushed or damaged by
this. The upper shell is now attached to the base plate again
with the housing screw (figure 3).
The room thermostat must only be operated with the
correctly attached and screwed-on upper shell. If the
upper shell is missing or wrongly installed, there is a
danger to life from electric shock!
16
8. Inserting or replacing the batteries
• Pull the battery holder from the bottom of the device.
• Insert the two batteries of type AAA (Micro) in the correct
polarity. Observe the marking in the battery compartment
holder.
• Return the battery holder to the room thermostat.
• Use only alkaline batteries.
Use only batteries of the specified type. Use alkaline
batteries for the longest operating duration.
The product is only approved for operation with 2x 1.5 V
AAA-batteries (Micro). No other energy supply must be
used.
Replace the batteries when the battery display flashes.

13. Maintenance and cleaning
Regularly check the technical safety of the device, e.g. for a
damaged casing.
If you have reason to believe that the device can no longer be
operated safely, disconnect it immediately and make sure it
is not operated unintentionally.
It must be assumed that safe operation is no longer possible
if:
• the device shows visible damage
• the device is longer working
• the device has been stored under unfavourable conditions
for an extended period of time or
• the device has been subjected to heavy stress during transport.
Always observe the following safety information before
cleaning or servicing the device:
Live components may be exposed if cover is opened.
The device must be disconnected from all power sourc-
es before any servicing or repair work is carried out.
Capacitors inside the device may still carry voltage even
though they have been disconnected from all power
sources.
31
Only qualified experts familiar with the hazards involved
and the relevant regulations must perform repairs.
The product requires no servicing apart from replacing the
rechargeable battery. Servicing or repair must only be carried out by a specialist or specialist workshop. Therefore,
never open it (except for the procedures described in these
operating instructions for insertion/replacing the batteries).
A dry, soft and clean cloth is sufficient for cleaning.
Do not put too much pressure on the display; this can cause
scratch marks, failures of the display or even destroy the
display.
Dust can easily be removed with a long-hair, soft and clean
