functIon
The MAX! Radiator Thermostat basic is responsible for regu-
lating 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.

7
Function
By using the MAX! Cube, several MAX! Radiator solu-
tions and MAX! Room solutions can be connected to
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.

10
Start-up
• 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 11). The radiator thermostat starts an
adapting run afterwards (see sec. “6.3 Adaption run” on
page 15).
A battery symbol ( ) on the display indicates that
the batteries need to be replaced. After removing the
empty batteries, wait approx. 1 minute before insert-
ing the new ones.
The service life of new alkaline batteries is approxi-
mately two years.
Operation with rechargeable batteries is not possible.
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.
Never recharge standard batteries. Do not throw
the batteries into a fire. Do not expose batteries

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
• Heimeier
• MNG
• Junkers
• Landis+Gyr (Duodyr)
• Honeywell-Braukmann
• Oventrop
• Schlösser
• Comap
• Valf Sanayii
• Mertik Maxitrol
• Watts
• Wingenroth (Wiroflex)
• R.B.M
• Tiemme
• Jaga
• Siemens
• Idmar
By means of the adapter in the delivery, the device can also
be installed on radiator valves of type Danfoss RA.

Start-up
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:
• 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).
In case of visible damage of the existing radiator, valve
or heating pipes, please consult a specialist.

Start-up
6.2.2 Danfoss RA adapter
The provided adapter is required for installation on Danfoss
RA valves. The Danfoss valve bodies have elongated notches
(G) around their circumference (see arrow), which also en-
sure that the adaptor is properly seated when it snaps on.
Please ensure that you do not trap your fingers be-
tween the two halves of the adapter!
During installation, please ensure that the pins inside the
adapter (H) are lined up with the notches (G) on the valve.
The RA adapter has been manufactured with pre-tension in
order to provide a better seat. Use a screwdriver during in-
stallation if necessary, and bend it open slightly in the vicinity
of the screw. Ensure that the adapter is properly clipped on.
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
(I) should be placed into the flange before mounting the ra-
diator thermostat.

aDaptIon run
Once the batteries have been inserted, the motor reverses;
meanwhile, "InS" and the activity 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 11).
• Tighten the union nut.
• Press the control wheel shortly 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 control
wheel; 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 to a MAX! Cube or Wall Thermostat+, the device
automatically switches to manual operation (Manu).
