Specifications
The RAS-C series is a programme of thermostatic
radiator sensors, which covers all central and
district heating systems.
Furthermore, the RAS-C range includes models
with features for positive shut-off and for
temperature limitation to provide the customer
with maximum flexibility.
RAS-C sensors are self-actuating proportional
controllers with a small P-band., designed for use
in 2-pipe domestic heating systems.
RAS-C 5042 is equipped with 2 m of ultra-thin
capillary tube, coiled up within the remote sensor
housing. After sensor mounting capillary tube is

mechanism, which ensures quick, firm and long
lasting mounting onto the valve body, without
the use of any tools.
The RAS-C construction is particularly robust,
with both end-stop strength limits and sensor
bending force limits being substantially above

Mounting
Theft Protection
The Danfoss snap-on coupling is easy to mount
and requires no use of tools, once the valve cover
has been removed.
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.
After mounting the sensor, press in the theft
protection clip.
The sensor is now locked to the valve.
To remove the theft protection without damaging
the sensor, use Danfoss special tool:
Code no. 013G1231
Setting the Temperature
Dimensions
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.
= Frost protection setting
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.
