SMART + WIFI RADIATOR THERMOSTAT
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 tools 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 adapters 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 extension 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 manufacturer 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.

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 appearance. For visual identification, the valve types are shown
schematically below and the corresponding adapters are illustrated.

Installation of M28x1.5 adapter:
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

from the valve.
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 notches (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 installing the radiator thermostat.
