Data sheet Thermostatic sensors RAS-C

Application

The RAS-C series is a programme of thermostatic

radiator sensors, which covers all central and

district heating systems.

RAS-C sensors are self-actuating proportional

controllers with a small P-band., designed for use

in 2-pipe domestic heating systems.

RAS-C sensors are equipped with a snap-lock

mechanism, which ensures quick, ﬁrm and long

lasting mounting onto the valve body, without

the use of any tools.

All RAS-C sensors incorporates a Frost Protection

Setting.

Furthermore, the RAS-C range includes models

with features for positive shut-oﬀ and for tem-

perature limitation to provide the customer with

maximum ﬂexibility.

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

pulled out to the required length.

The RAS-C construction is particularly robust, with

both end-stop strength limits and sensor bending

force limits being substantially above the require-

ments of the European Standard EN 215.

Temperatures stated for Xp = 2K, i.e. the valve is closed at 2 °C higher room temperature.

The remote sensor is delivered with 2 m of capillary tube coiled up within the sensor. When mounting the sensor, only

the capillary tube required is uncoiled.

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 manu-

ally by turning the tightening ring.

To remove the theft protection without damaging the sensor, use Danfoss special tool: Code no. 013G1231 Setting the temperature  = Frost protection setting 0 The required room temperature is set by turning the setting dial. The temperature scales show the correlation between scale values and the room temperature.
