Application

Operation

Setting the
temperature

Thermostatic sensor type RTS-R EverisTM 4240 and
4280 can be fitted without adapter on valve radiators
(compact radiators) from the manufacturers: Baufa,
Brötje, Brugman (Piano, VK), Buderus, CICH

The thermostatic sensor with a liquid-filled bellows
system provides proportional regulation. The sensor
is actuated by ambient temperature. 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 liquid pressure

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.

rises in the bellows, moving the valve cone towards
the closed position until equilibrium exists between
the bellows and the spring.
On a drop in ambient temperature the liquid 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.

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.

Different temperatures are recommended depending
on the purpose of the room. The illustration shows
the most frequently used.

Remove the protective cap of the valve.

Before mounting, slack the connection nut of the
sensor and turn the setting dial on position 5.

Then press the sensor on the valve and secure the
connection ring by hand (5 Nm) to firmly connect
the sensor with the valve.

Setting the upper limit

e.g. 3 as the highest possible temperature selection:

1. Turn the handle to max. position.

2. Keep the limiter tab to the right of the scale pointer
pressed down with a small screwdriver.

3. Turn the handle to 3 on scale and release the tab.

Setting the lower limit

e.g. 2 as the lowest possible temperature selection:

1. Turn the head to. min. position.

2. Keep the limiter tab to the left of the scale pointer
pressed down with a small screwdriver.

3. Turn the head to 2 and release the tab.
