Data Sheet
Thermostatic Radiator Sensor, Type RAW with
RTD Connection
Application
Ordering and Technical
Data
The sensors are equipped with RTD connection.
RAW 5216 is identical to 5215 except for the
temperature range 16 - 28 °C.
The RAW 5215 sensor incorporates a frost
protection setting for maximum user flexibility.
RAW/RTD 5215/5216
The RAW series is a programme of radiator
thermostats which covers all central and district
heating systems.
RAW is a self-actuating proportional controller
with a small P-band.
RAW radiator thermostats are designed for use in
2-pipe domestic heating systems.

RAW 5215 Built-in temperature sensor RAL 9016 8-28 °C 013G5215
RAW 5216 Built-in temperature sensor, limited temperature area RAL 9016 16-28 °C 013G5216
The RAW sensors also provide the option to limit
the temperature range. On 013G5215 both
maximum and minimum setting temperature can
be limited. On 013G5216 only the maximum
temperature can be limited.
The RAW design is particularly robust, with both
End-Stop strength limits and sensor bending
force limits being substantially above the
requirements of the European Standard EN215.

Temperature Setting
Mounting
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 influ-enced by
installation conditions.
1. 2.
= 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.
3. 4.
An open-end spanner is used for mounting the
sensor onto the valve body (1 & 2).
The sensor should always be placed where the
room air can circulate freely around it.
RAW5215 only
Setting the upper and lower limit
The thermostat features two tabs with which the
temperature setting area can be decreased. If 4
should be max. setting, turn the thermostat to
max. position (3) and press and hold right tab
while turning the thermostat to 4 (3), now release
tab. With the left tab the lower temperature must
be turned to min. position (4).

Dimensions
The RAW thermostatic sensor operates with a
liquid filled bellows system, which provides
proportional control, as opposed to On/Off.
The sensor is actuated by ambient temperature
changes. The calibrated pressure in the bellows
corresponds to the temperature of the charge.
This pressure is balanced by the force of a
regulating spring.

On a rise in ambient temperature, the pressure
increases in the bellows, moving the valve cone
towards the “closed” position, until equilibrium
exists between the bellows and spring. On a drop
inambient temperature, the pressure falls,
allowing the bellows to contract and the valve
cone to move towards the “open” position until a
state of equilibrium is re-established.
