5
Function
Using the device for any purpose other than that de-
scribed in this operating manual does not fall within
the scope of intended use and shall invalidate any
warranty or liability. This also applies to any conver-
sion or modification work. The device is intended for
private use only.
3 functIon
The MAX! Radiator Thermostat is responsible for regulat-
ing the radiators within the MAX! system. During ventila-
tion, the MAX! Radiator Thermostat automatically reduces
the temperature in a room in order to save on energy costs.
Communication between the MAX! components is bidirec-
tional. This ensures that the information sent reaches the
recipient.
The configuration of the MAX! Radiator Thermostat depends
on the system variant used. You have the possibility to choose
between the following two variants:
MAX! House Solution
This is the solution for the entire house. With a MAX!
Cube, all settings of connected devices in your house
can comfortably be made via the MAX! software.
By using the MAX! Cube, several MAX! Radiator solu-
tions and MAX! Room solutions can be connected to

6
Function
a new MAX! House solution in a new installation. In
this installation, the MAX! Eco Switch can optionally
be integrated.
MAX! Room solution
In the room solution, the settings of all connected
devices in your room can comfortably be made via
the MAX! Wall Thermostat+. Up to 8 MAX! Radiator
Thermostats and 8 MAX! Window Sensors can be con-
nected and controlled via the MAX! Wall Thermostat+.
The MAX! Wall Thermostat+ has an internal sensor
that measures the temperature in the room and cycli-
cally transmits it to the radiator thermostats.
With a MAX! Cube, the solution can be extended to a
House solution.

tor Thermostat is in automatic mode (Auto) and the comfort
temperature ( ) of 21.0°C is set. The antenna symbol ( )

6.1 InsertIng (replacIng) batterIes
To insert the batteries into the MAX! Radiator Thermostat,
please proceed as follows:
•Remove the battery compartment cover by pushing it
forwards.
• Insert 2 LR06/mignon/AA batteries in the battery compart-
ment, making sure they are the right way round.
• Reattach the battery compartment cover and latch it into
place.
After inserting batteries, the radiator thermostat has to be
mounted on the radiator (see sec. „6.2 Installation on the
radiator“ on page 9). The radiator thermostat starts an

9
Start-up
adapting run afterwards (see sec. „6.3 Adapting run“ on
page 17).
A battery symbol ( ) indicates that the batteries need to
be replaced. After removing the batteries, you should wait
approx. 1 minute before inserting the new ones.
The service life of new alkaline batteries is approxi-
mately two years.
This device does not support operation with recharge-
able batteries.
Never recharge standard batteries. Doing so will pre-
sent a risk of explosion. Do not throw the batteries
into a fire! Do not short-circuit batteries.
Used batteries should not be disposed of with
regular domestic waste! Instead, take them to
your local battery disposal point.
6.2 InstallatIon on the raDIator
The MAX! Radiator Thermostat is easy to install and can be
done without draining heating water or intervening in the
heating system. No special tools are required, nor does the
heating have to be switched off.
The union nut attached to the radiator thermostat can be
used universally and without accessories for all valves with
a thread size of M30 x 1.5 from the most popular manufac-
turers such as

• Mertik Maxitrol
•Watts
•Wingenroth (Wiroflex)
•R.B.M
•Tiemme
• Jaga
•Siemens
•Idmar
By means of the adapters in the delivery, the device can be
installed on radiator valves of type Danfoss RA, Danfoss RAV
and Danfoss RAVL.
6.2.1 Removing the old dial
Rotate the thermostat dial to the maximum value (1) (an-
ti-clockwise). The thermostat dial then no longer presses
against the valve spindle, making it easier to remove.
There are different ways of fixing the position of the ther-
mostat dial:

11
Start-up
• Union nut: Unscrew the union nut in an anticlockwise di-
rection (2). The thermostat head can then be removed (3).
•Snap-on fastenings: Thermostat dials that have been at-
tached using this method can be easily released by giving
the lock/union nut a slight turn in the anticlockwise di-
rection (2). The thermostat head can then be removed (3).
•Compression fitting: The thermostat dial is held in place
by a mounting ring which is held together with a screw.
Loosen this screw and remove the thermostat head from
the valve (3).
• Threaded connection with set screw: Loosen the set screw
and remove the thermostat head (3).

6.2.2 Adapter for Danfoss
One of the provided adapters is needed to attach to Danfoss
valves. The assignment of the suitable adapter ring to the
relevant valve can be found in the following illustrations.
Please ensure that you do not trap your fingers be-
tween the two halves of the adapter!
The Danfoss valve bodies have elongated notches (I) around
their circumference (see arrow), which also ensure that the
adaptor is properly seated when it snaps on.
During installation, please ensure that the pins inside the
adapter (J) are lined up with the notches (I) on the valve.
Ensure that a suitable adapter for the valve is properly
clipped on.
The RA and RAV adapters have been manufactured with pre-
tension in order to provided a better seat. Use a screwdriver
during installation if necessary, and bend it open slightly in
the vicinity of the screw. After clipping onto the valve body,
please attach the adapter using the provided screw and nut.

6.2.3 Support ring
The valves from different manufacturers may have tolerance
fluctuations that make the radiator thermostat more loosely
seated on the valve. In this case, the provided support ring
(L) should be placed into the flange before mounting the ra-
diator thermostat.

Start-up
6.3 aDaptIng run
Once the batteries have been inserted and date and time have
been set, the motor reverses; meanwhile, "InS" and the ac-
tivity symbol ( ) are displayed. As soon as "InS" is displayed
without the activity symbol ( ), the radiator thermostat can
be mounted. This is followed by an adapting run ("AdA") to
adapt the thermostat to the valve.
• Attach the radiator thermostat to the valve (see sec. „6.2
Installation on the radiator“ on page 9).
• Tighten the union nut.
• Press the Boost button when "InS" is displayed.
Now the radiator thermostat performs an adapting run. "AdA"
and the activity symbol ( ) are displayed; during this time,
operation is not possible.
If the adapter run has been initiated prior to mounting or if
an error message (F1, F2, F3) is displayed, press the Boost
button; the motor reverses to the "InS" position.
Teach-in mode can be activated even whilst "InS" is
still displayed.
If the MAX! Radiator Thermostat has not been taught-
in on the MAX! Cube, the device automatically switch-
es to manual operation (Manu).

Teaching-in
7 teachIng-In
In order to be able to use the MAX! Radiator Thermostat in
your installation, you must teach it in first. The teach-in pro-
cedure depends on the system variant used. Choose your
system variant (House or Room solution) and follow the in-
structions below.
MAX! House solution
In the MAX! House solution all settings and pro-
grammings (e.g. week programs) can be made via
the MAX! software.
• Put the MAX! Cube into teach-in mode. Start the local MAX!
software and click on "New device" (1).
• Toactivateteach-in modeon theradiatorthermostat,press
and hold down the Boost button for at least 3 seconds. The
display shows the remaining teach-in time in seconds. The
teach-in time is 30 seconds.

back to normal display.
As soon as the MAX! Radiator Thermostat has been
taught-in to a MAX! Cube, all settings will be trans-
mitted via radio .
The MAX! Radiator Thermostat can only be taught-in
to one MAX! Cube.
If the MAX! Radiator Thermostat has already been
configured via a MAX! Wall Thermostat, a factory re-
set has to be performed before teaching-in the device
to a MAX! Cube (see sec. „13 Restore factory settings“
on page 25).
MAX! Room solution
In the MAX! Room solution all settings and program-
mings (e.g. week programs) can be made directly via
the MAX! Wall Thermostat.
•Press and hold down the
OK button of the MAX! Wall Ther-
mostat for at least 3 seconds to activate teach-in mode (1) .
• Activate the teach-in mode of your MAX! Radiator Ther-
mostat. Press and hold down the Boost button for at least
