4. Function
With the Radiator Thermostat Model M you can conveniently
regulate the room temperature. Thanks to pre-programmed
or individually tailored heating and non-heating phases the
desired temperature can be comfortably adjusted. The device
moves a valve to control the ow of heat to the radiator. The
radiator thermostat ts to all common radiator valves and is
easy to install without having to drain any water or intervene
in the heating system. The additional boost function enables
quick, short-term radiator heating by opening the valve for 5
minutes. This immediately brings a comfortable warmth to the
room.

display, the radiator thermostat can be installed on the valve.
• The week program and other settings can be adjusted before
installation. Press the Mode/Menu button for this, while "INS"
is shown in the display. You will nd further information in
chapter "11. Setting week program".
• After the programming has been completed, "INS" is shown
again in the display and installation can take place.
9. Installation on the radiator
The radiator thermostat is easy to install where thermostatic
valves have previously been tted, and can be done without
draining heating water or intervening in the heating system.
No special tools are required, and the heating does not have
to be switched off.
It is recommended to install the device while radiators /
pipes are not hot.
The union nut attached to the radiator thermostat can be used
universally and without accessories for valves of the most
popular manufacturers with a thread size of M30 x 1.5 mm.
9.1 Removing the old dial
• Rotate your existing thermostat dial to the maximum value
(anti-clockwise). The thermostat dial then no longer presses
against the valve spindle, making it easier to remove.
• Now remove the thermostat dial.
• If required, x one of the supplied adapters. Afterwards, the
adaption run can be initiated (see chapter „10. Adaption run“).
9.2 Adapters for Danfoss valves
By means of the adapters included in the package, the device
can be installed on radiator valves of types Danfoss RA, RAV
and RAVL.
The assignment of the suitable adapter ring to the relevant
valve can be found in the following illustrations.
The Danfoss valve bodies have elongated notches (I) around
their circumference (see arrow), which also ensure that the
adapter is properly seated when it snaps on.
If required, place the provided support ring (L) into the
ange before installing the radiator thermostat.
During installation, please ensure that the pins inside the
adapter (J) are lined up with the notches (I) on the valve.
Ensure that the adapter is properly clipped on.
Take care during installation that you do not trap your
ngers between the two halves of the adapter!
The RA and RAV adapters have been manufactured with pre-
tension in order to provide 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.
