Application
RA 2990 RA 2992 RA 2920 RA 5060
The RA series is a comprehensive programme of
radiator thermostats which covers all central and
district heating systems.
RA is a self-actuating proportional controller with
a small P-band.
The RA sensor range includes:
RA 2990: built-in sensor with frost

protection, temperature range 5-26°C,
facilities for limiting and locking the
temperature set-point. A score on energy
efficiency. RA 2990 and 2992 sensors are
equipped with a snap-lock mechanism
which ensures quick, firm and long lasting
mounting of the sensor.
RA 2992: remote sensor with frost

protection, temperature range 5-26°C,
facilities for limiting and locking the
temperature set-point.
RA 2920: Tamperproof model with built-in

temperature set-point.
RA 2992 and 2922 are equipped with 2 m of ultrathin capillary tube, which is coiled up within the
remote sensor housing. After sensor mounting
capillary tube is pulled out to the required length.
range 8-28°C, facilities for limiting and

RA 5062: length of capillary tube 2 m
▪
RA 5065: length of capillary tube 5 m
▪
RA 5068: length of capillary tube 8 m

The snap-lock sensors are easy to mount and
requires no use of tools.
The sensor is fitted to the valve by applying a
gentle pressure. When the sensor is in place, the
snap-on mechanism is activated and the sensor
has been correctly mounted.
If mounting and dismounting are carried out
again, the mechanism must be tightened
manually by turning the tightening ring.
All thermostatic sensors can be combined with all
RA 2000 valve bodies.
The technical data for RA valve bodies in
combination with RA sensors meet Euronorm EN
215.

Data Sheet Thermostatic Sensors Type RA 2000
Setting the Temperature
The required room temperature is set by turning
the setting dial. The temperature scales show the
correlation between scale values and the room
temperature. The temperature values stated are
for guidance only as the obtained room
temperature will often be influenced by
installation conditions.
The temperature scales are stated according to
European standards at Xp = 2°C. This means that
the radiator thermostats close at a sensor
temperature which is 2°C higher than stated on
the temperature scales.
RA 2990 /92 RA 2920/22
Locking and limitation of the temperature setpoint of RA sensors are carried out using the
limiter pins placed at the back of the sensor.
Locking and max/min limitation of the remote
temperature adjuster type RA 5060 are carried
out by the limiter tabs. The limiter tabs will be
covered by the setting dial.
The procedure is described in the instruction.
