3 Identify Radiator Valve
The radiator thermostat is easy to install and can be mounted without draining
the heating water and without interfering with the heating system. No special to-
ols are required and the heating system does not need to be switched off. The
built-in connecting nut M30x1.5mm can be used universally for most common
valve manufacturers without the need for additional adapters. For Danfoss RA/
RAV/RAVL, Giacomini, Caleffi and M28x1.5 valves, the valve connection adap-
ters are included in the accessories package.
valve body
Remove the old mechanical thermostat head from the valve to access the valve
body. Check which valve is installed to select the correct installation variant. If your
valve body has a thread, continue with section 4. If your valve body has clips
without threads, continue with section 5. of this document.
4.1 Valve Body with M28x1.5 Thread
The M28 adapter is suitable for almost all valve bodies with M28 x 1.5 mm connection thread. To compensate for different valve heights, this set includes 4 different exten-
sion pins. If the manufacturer of the valve can be recognized by a print or symbol on the valve, then select the correct pin according to the following table. If the manufactu-
rer cannot be identified, the closing dimension of the valve can also be determined as an alternative. To do this, press the valve pin all the way down (the valve is then fully
closed) and measure the height of the valve pin relative to the surface of the adapter (A). The appropriate extension pin can then be taken from the second table.
Pin No. Pin Size Valve Close Size (A)
1 24.0 mm 1.0 - 3.0 mm
2 18.5 mm 6.5 – 8.5 mm
3 17.0 mm 8.5 -10 mm
4 15.0 mm 10.0 – 12.0 mm
5 Valve Body with Clip
(no Thread)
Check which adapter is required for the installed valve body. The valve can be
identified either by the corresponding marking on the valve or by its visual appe-
arance. For visual identification, the valve types are shown schematically below
and the corresponding adapters are illustrated.

Installation of M28x1.5 adapter:
threads
Insert the extension pin into the adapter attachment from
the inside. This is only possible in one position, as one side
of the extension pin is flattened to prevent it from twisting.
Turn the old mechanical thermostat head to the maximum
value. This prevents the thermostatic head from pressing on
the valve spindle and makes it easier to remove. Loosen the
union nut completely. Turn it counterclockwise. The head
can now be removed from the valve.
Pin No.
Screw the adapter clockwise onto the valve thread. Do not
use tools such as wrenches or pliers, as this could damage
the adapter. Finally, screw the new thermostat onto the
adapter.

During installation, make sure that the pins inside the adapter (2) match the not-
ches (1) on the valve body. Ensure that the appropriate adapter for the valve is
clipped on correctly. The valves of different manufacturers may have tolerance
variations, so that the radiator thermostat sits more loosely on the valve. In this
case, the supplied support ring (3) should be inserted into the flange before in-
stalling the radiator thermostat.
